Common activities that we take for granted contribute to waste-water in the environment include lavatory, cooking and bathroom water. Yet, as Australia advances as a country, concern is being raised about in regards to industrial water waste and pollution. Due to this concern, aeration equipment in waste-water treatment has spurned advances on new technology.

Research shows the demand for such equipment is on the increase and will reach its apex by 2020. By the turn of this decade, the global value of wastewater aeration equipment will amount to $8.39 billion. There are a number of factors that contribute to popularity of these systems, but chief among them is the increased awareness about environment. Many jurisdictions have developed guidelines that make sure people preserve the environment.

How Aeration of Waste Water Works

Aeration equipment can turn wastewater into a very clean and hygienic product. Waste water treatment equipment relies on microorganisms to handle very dirty water. The microorganisms are used in wastewater aeration equipment to digest the organic waste aerobically. This process is important because it reduces the amount of disease-causing organisms in the waste. Through aeration, the amount of sludge in the waste-water is reduced and pollution is controlled.

 Waste water aeration equipment can be categorized as waterfall, mechanical and diffusion aerators. The bubble or diffusion aerator operates on the principle of air diffusion. In this process, air is introduced from blowers into the aeration tanks. Some of the equipment that falls under this category are pressure aerators and air stripping equipment. In addition, there is the waterfall aerator, whose principle is water falling from a height leading to contact between water and air. In this process, the idea is to introduce water into air. Examples of such waste water aerators include cone aerators, cascade aerators, draft aerators, slat and coke aerators, and spray aerators. On the contrary, mechanical aerators rely on impellers or may incorporate air injection components.

With growth to a more energy-efficient world, wastewater aeration equipment has had its own share of transformations. The design developments in aerators are focused on more energy-efficient equipment. Major innovations are happening in the diffused systems arena, especially the fine-pore membrane systems. Custom Fans of Australia can help you in choosing your waste water aeration equipment or any other fan systems or arrangements that you may need.

High Pressure Centrifugal Design

Regular to moderate pressure Centrifugals consist of an open impeller with specifically designed ribs or blades. The ribs can be seen at the inlet of the impeller which is located at the eye of the wheel. The housings are fairly thick and the impellers are fat in size. These centrifugals create good pressures during operation and are sometimes constructed out of sheet metal and not so strong housings. They are relatively open and the moving parts can be easily seen. Some very efficient and sturdy designs consist of backward inclined blades to keep particles from building up on the inside and directly on the impeller’s contact area. Particle build up can cause unwanted turbulences and hence contribute to lowered efficiency and function.

High pressure Centrifugals are very thin and the impeller is closed off except at the eye and the circumference. These centrifugals are very efficient and are built for extremely high static pressures. They are constructed from stainless steel and strong alloys. Good designs of High Pressure Centrifugals are split in the middle and allow the housing to be de-assembled to access the impeller for cleaning without messing with connections to the inlet or outlet such as ducting or dampers. High Pressure Centrifugals are good for up to 20,000 pascals. Due to the high heat generated by operation, the shaft can be cooled to ensure longevity and continuation of operation. These centrifugals tend to be very noisy, so a silencer can be fitted to assist with acoustic treatment and lower operating decibels. The exposure to corrosive gases, liquids or solids can be handled with special coatings that will protect the materials and metals from corroding or breaking down.

A High Pressure Centrifugal as a Ventilator?

High Pressure Centrifugals are rarely used as ventilators or man coolers. This is due to the fact that high pressures that are created after being processed by the impeller wheel create unfavorable breathing environments exactly at the outlet.

By carefully managing and expanding the volume, High Pressure Centrifugals can be used as ventilation devices however. A careful selection of strong and tough materials should be considered when attaching ducting or connections at the inlet and outlet so that they don’t succumb to the high pressures or vacuums. Industrial ventilation systems for factories and human occupied spaces have to receive careful pressures and conditions. A High Pressure Centrifugal can be used in the case where the fan is located at a far distance from the required space for ventilation, or if there are many spaces to ventilate with a single fan. The fan would have to overcome many resistances such as corners in the ducting, dampers and pressures from each room. By expanding the duct and increasing the supply area, the pressure can be significantly lowered by the time the air arrives at its destination. For applications such as this, it is important that Custom built Centrifugals be chosen to create precise and careful conditions.

High Pressure Centrifugal fans, like the type that Custom Fans design,  are great for applications such as pressure testing, dust removal and solid aeration. Dust collectors or bins can be connected at the outlet of a centrifugal to pull air from the inside of a room. The inlet of the fan would be attached to a duct which does the extraction through a round duct. Consult the relevant professionals that have years of experience designing these systems. The correct balancing and proper pre-engineering design ensures that High Pressure Centrifugal Fans operate at their best.

Not surprisingly, industrial fans are manufactured with more robust and generally higher quality materials than their lower cost residential cousins. The service environment that industrial fans are called to operate in necessitate this difference in quality. Not every industrial environment is corrosive or abrasive, just like not every residential application is spotlessly clean. However, the industrial fan will generally be called upon to work harder and longer than a lightweight residential fan.

Price is an Important Factor

Residential fan buyers are generally unwilling to pay for the extra quality that goes into an industrial grade fan. Plastic parts are good enough, and if the product breaks down, full replacement is affordable. The motor of the industrial grade fan is another difference. In both cases, the motor may burn out if it is allowed to be overused or get dirty (dirty blades contribute to overloading and motor burnout). It is easier and cheaper to replace the entire unit with a residential fan, yet should the motor of an industrial grade fan burn out, it is often repairable by replacing components such as bearings, bushings, windings or brushes.

Industrial fan blades, like the types that Custom Fans supplies, are a common replacement part. Blades are vulnerable damage in an industrial environment, so a replacement makes good economic sense when the rest of the unit is in good shape. Many industrial fans are custom made for their application, therefore manufacturers embrace modular construction. This means that if a fan is in otherwise good shape, but the purpose for which it was purchased has changed, the motor and mounting hardware can often be salvaged and used with new blades, saving money for the business owner in the long run.

Industrial Fan Blade Considerations

Industrial fan blades are usually made of steel, although there are cast or fabricated aluminium and stainless steel blades available. Plastic blades are generally only available for residential and commercial grade fans, although fibreglass blades may be called upon for use in a corrosive industrial environment.

It is usually possible to unbolt the individual blades from the common hub of an industrial fan for replacement. It is generally not considered to be best practice to replace blades individually. Especially in the case of high speed fans, replacing the entire blade set helps to ensure that the balance of the fan is maintained. Although weight differences between old and new blades may be imperceptible, minor differences may contribute to shaft wobble. This can shorten the life of the fan motor.

The impellers for centrifugal fans, or “blower wheels”, are generally replaceable as well. Their high operational speed and the fact that they are often designed to fit specific housings often mean that the original manufacturer is usually the only option for blower wheel replacement. Forward curved multi-vane type blower wheels are an exception. Also known as “Squirrel cage” fans, common enough in HVAC use that it may be possible to find a replacement from sources other than OEM. IF you are looking for industrial fans blades or fans in general, Custom Fans of Australia would be happy to help you.

Grain stored in a bunker or silo does not have natural airflow movement to that of outdoor (air). For example, in the winter season, interior storage systems get filled with moisture due to the lack of air movement and circulation, it is then that mould develops which inevitably causes grain to deteriorate.

When Should I Use a High Temperature Fan?

When you need to remove:

• Unwanted heat
• Condensation
• Humidity

This is especially important when you have a large amount of grain stored.  Because weather and temperature are unpredictable these high temperature fans will help to protect your grain harvest and maintain the highest quality.

Lack of air circulation allows breeding ground for insects and mould due to poor moisture content level. Humidity in stored grain creates undesirable moisture content making stored grain unviable. When unwanted substances are removed it allows natural air circulation to circulate freely and stabilise the internal temperature of the stored grain, this in turn eliminate possible insects breeding and infestation.

Control Condensation

Placing an exhaust fan above the roof helps to minimise humidity and condensation in the storage/silo. Even when there is aeration equipment being used, if the grain moisture is too high, it can still cause spoilage. Once grain is in storage, even with proper moisture content; it must be monitored to keep it in the accepted range. Moisture can come from anything; leaky hatches, downspouts or bucket elevators. The exhaust fan also gives way to fresh air circulation by pulling fresh and cool air into the storage area.

In a continuous process, the exhaust fan keeps the grain drier, diluted air at the bottom of the grain moves upward through the surface grain making it less likely to experience condensation.

Types of Exhaust Fan

Most fans can be categorised into three categories:

• Axial flow fans/ propeller fans
• Centrifugal fans
• Cross-flow fans

A)   Axial flow fans/ propeller fans

Axial fans usually have 4 or more long blades attached to small hubs. It normally can generate up to 5 centimetres in water pressure. It helps to exhaust air from attics, overhead spaces and general air circulation. However, these types of fan are not recommended for cooling or drying aeration.

–          2A) Sub axial fans – Tube and Vane axial

Unlike normal axial fans, sub axial fans — Tube and Vane — have opposite properties. They have larger hubs and shorter blades that help to cool the airflow and capture undesirable heat.

B)   Centrifugal fans

Centrifugal fans have backward curve or backward inclined blades. The effectiveness and efficiency of these blades can generate more than 7 centimetres in water pressure. Another advantage of these fans is that they can produce more air volume for a given air volume pressure. However, improper selection on these fan types can damage the motor when operated outside certain pressure ranges. Contact Custom Fans for professional advice.

C)   Cross-flow fans

Unlike axial fans, the cross-flow fan uses an impellor with forward curved blades. Its fans are long in relation to the diameter.

The advantages of these fans are the allowable length – it can be adjusted to meet the flow rate requirement, its operating noise is less when compared to axial fans while also having the ability to provide a high pressure coefficient.

Choice of Fan

The type of fans that will help optimise or maintain a quality grain supply depends upon the type of storage, aeration (cooling and drying) system and climate. Proper selection of a high temperature exhaust fan will help to preserve the quality of the grain while in storage, avoid loss and make you more money at market.

As airflow requirements increase, there are two basic engineering options that Custom Fans can assist you with. The first is to increase the efficiency of normal sized fans; the other is to simply design larger fans. There is some performance gain by using air foil shapes for fan blades. Placing an axial flow fan in a duct or tube will markedly increase performance and efficiency by negating blade tip vortex efficiency loses. Blade tip vortex occurs when air falls off the tip of the blade. This phenomenon occurs in many aerodynamic applications, and is the reason that small winglets are mounted on the wings of jet liners.

Diminishing Returns

A fan is an essentially simple machine, so simple that it is a difficult concept to improve upon. There comes a point where the only way to increase output is to increase the size of the machine. Increasing motor power will increase airflow and velocity, but power increases alone soon reach a point of diminishing returns. Increased motor power is a way to increase blade speed, but there is a limit to the effectiveness of increased blade speed, a fan blade moving at Mach 1 will make a lot of noise, but may not be moving a significant amount of air.

Once the aerodynamic efficiency has reached its maximum, the only remaining way to increase airflow capacity is to increase the size or number of fans. Very large industrial fans are often custom made for each application. This is partly due to the low demand for fans of such a large physical size, but there is also transportation to be considered. It may be simpler to carry the component parts to the industrial site and assemble the fan locally than it would be to transport an over-sized, fully assembled fan.

In normal sized industrial fans, the blade assembly is usually directly coupled to the motor shaft. This may not be a practical solution for very large industrial fans. Because of the torque and physical size of the fan motor, mount the motor to the frame of the fan and driving the blades with a belt or chain may be a better option. Motors of this size often have a significantly increased service life if “soft start” circuitry is incorporated into their controls.

Very Large Industrial Fans

The HVAC systems of the huge Internet server farms often require very large industrial fans. These server warehouses are often built in areas of abundant low cost energy, such as hydro-power, because a very significant portion of their operating budget goes toward air conditioning and cooling costs. The main circulating fan for these large HVAC systems may look just like the squirrel cage fan in your central AC system at home, but the casing shroud will be the size of small house.

Another large industrial fan application is HVLS technology. High Volume, Low Velocity fans were developed for the dairy industry. A fan which is six to twenty four feet in diameter is more efficient, but aerodynamically and in energy consumption, than a number of smaller fans that it replaces. The airflow will be smoother and steadier, which contributes to greater evaporative cooling and comfort in the space.

These industrial fans and blowers are designed to move large volumes of air to cool and ventilate offices and workshops.  These fans are used widely in industries for increasing flow rates of fluids, but mainly air. Fans are designed according to the type of process, fluid, and desired flow rate which are mounted on a shaft which is driven by a high power motor. The shaft is a rod which connects the motor with the fan (rotor element).

Industrial fans have several uses that are applied in different operations and processes such as combustion, aeration, cooling, drying, exhaust, ventilation, air-cleaning, particulate transport. Air blown from industrial fans can also be applied in electrical power production, cement production, pollution control, mining, metal manufacturing and processing, petrochemical, and food processing. The two main industrial fan categories are centrifugal fans and axial fans. Do you know what type of fan you need?

Centrifugal Fan Principle

Industrial centrifugal fans are one of the most widely used fan type which operate on the centrifugation theory and thusly named. The centrifugal force of the fan blades pushes the fluid (liquid, gases) by applying a force. The stationary part of the pump is known as a stator and the moving part is known as a rotor. The rotor is fixed on a stator. A moving impeller is joined on a rotor which rotates. The fan blades are cut at different angles to provide the optimum centrifugal force to the fluid. The fluid then comes in contact with the impeller blades, due to centrifugation action, the fluid moves towards the outer periphery with a greater force and thus moves with a greater velocity. This whole assembly is fitted into a metallic casing.

Axial Flow Principle

Industrial axial fans allow the fluid to move in the parallel direction to that of the axis of the rotation of the impeller. This is in contrast to centrifugal fans which direct flow at right angles to the propeller. Axial fans are best suited where high flow and lower resistance applications are required. Blade width, number of blades, width of propeller, propeller speed and the angle of cuts on the blades, plays an important role in the characteristic performance of axial fans.

The axial fans come in different dimensions according to their need in the process they are being used. For example the most common type of fan for an air-cooled heat exchanger (ACHE) is less than 14 feet in diameter, comprising of 4 blades. The design for wet cooling towers is 28 feet in diameter, comprising of eight blades. Axial flow fans are used for localised cooling purposes.

 Some ventilation systems where there is no room for larger sized fans, axial fans are installed instead. These types of fans are often found in small electrical and mechanical gadgets for cooling purposes due to the limited space for fan installation. Axial fan swirl patterns are differ when fans are allowed to run at different speeds.

Industrial Fan Specifics

Industrial fan design can be determined via several paths. For small industrial fans, the diameters of fans are usually kept in the range of 1.2 meters. For the larger fans, more complex design is required. Perfect engineering and application of fluid dynamics principles are required for the best performance.

Materials of construction of fans are selected by keeping different parameter and factors in mind. The fluid flow rates and type of fluid being circulated play a significant role in fan design. The type of fluid, corrosiveness and abrasiveness factors will determine the construction materials of fan. High speed fans imply more force on the rotating body structure; determining excessive stresses should be eliminated when considering fan design–using finite element analysis and computational fluid dynamics is common. CAD and other computer simulation tools aid help in designing the perfect industrial fan, but if you are interested in an industrial fan hire, don’t hesitate to contact Custom Fans for assistance.

Centrifugal fans Australia based users have come mostly from different industrial players in the country. Centrifugal fans have become the most logical and economical options for industries such as food, agriculture, pharmaceutics, construction, etc. when faced with ventilation, temperature control and dust management concerns. And it could not have just happened by chance. There are a couple of reasons why these types of fans have been one of the most prevalent units in the heating, ventilation and air conditioning (HVAC) field.

Centrifugal Fans Australia: Cost-efficiency is the Name of the Game

One of the main reasons for the Australian industries’ patronization of centrifugal fans is the cost-efficiency that they bring on the table. Centrifugal fans are usually cheaper than axial fans and are easier to construct. Regardless of size or power, a single centrifugal fan unit could achieve what is expected of it as long as it is used within the bounds of its capacity or even slightly above.  The centrifugal fan’s ability to move large volume of high pressure air while not compromising energy efficiency and maintaining manageable costs–is a huge upside.

Common Australian Industries that Employ Centrifugal Fans

Australia is mostly known as a country largely dependent on its agricultural industries. So it comes as no surprise that agriculture is one of the leading industries in terms of centrifugal fans usage. In several agricultural sectors, ventilation and temperature control is very crucial. One good example is in the production of grain.

Centrifugal fans play a major role in the process called grain aeration. The Grains Research and Development Corporation defines grain aeration as a “popular grain storage tool offering harvest flexibility, increased marketing opportunities and better control of grain quality, both at harvest and during storage.”  This process inhibits and mitigates the development of moulds and insects in the produce by keeping the moisture level of grains within the standard level. All that is achieved by maintaining the right mix of humidity, temperature and dust composition inside the silos where the grains are contained. And proper aeration system setup centred on a centrifugal fan is the ideal and trusted way to get through this undertaking.

Another industry where centrifugal fans are of big help is the mining industry. With lots of underground work, dust and air pollution to deal with, mining needs a ventilation system that offers flexible volume and pressure control. And centrifugal fan-based ventilation system coupled with dust control units offer just that.

Custom-Built Centrifugal Fans Australia

The above-mentioned industries usually have their own set of specifications and preference for their centrifugal fan systems. Factors such as infrastructure architecture or geographical location come into play when dealing with large and complex area of operation. Because of this, these industrial entities often go for custom-built or made to order centrifugal fans. This gives them the flexibility to decide on the blueprint of their own ventilation systems and discuss with ventilation professionals the best possible approach to take. This particularly applies for industrial entities with minimal background in ventilation systems.

The Bottom Line

While centrifugal fans are widely employed around the world across different industries, they are deemed to be most vital in the agriculture, mining and manufacturing ones. These industries are some of Australia’s largest and most profitable. The production of these industries could be significantly hampered if centrifugal fan ventilation systems are taken out of the picture.

With money, production quality and reputability on the line, it is no wonder why these industries comprise a huge chunk of centrifugal Custom Fans Australia based users.

The impeller is a type of rotor, specially constructed with ribs and blades to force air toward the circumference of the wheel when it spins. The housing has a built-in inlet and outlet, and contains the rotating impeller. Housings keep a regulated pressure range due to their constant volume. The shaft is the axis about which the impeller rotates. It connects to the drive to transfer torque or rotation. The drive provides the rotating force to the impeller. The shaft can be driven by an electric or diesel motor, a belt connected to a rotating device or a coupling.  Many high pressure applications use internal combustion engines to generate the torque required. Efficient Diesel engines with high compression ratios are usually perfect as they are very efficient and provide a strong torque or rotating force compared to the power input. Basically, a centrifugal blower works by sucking air at the eye of the impeller wheel inlet and expelling at the circumference’s outlet at 90 degrees to the direction of the intake air.

Blowers, Not Fans

They are labelled as blowers and not fans because they serve the purpose of overcoming resistances such as solid particles and restrictions in the air flow. Fans generally only provide ventilation and air or gas movement. High Pressure Centrifugal Blowers are rarely used for human ventilation unless the air is being transported over a considerable distance to lower the pressure by delivery to the space.

These applications can be seen in large HVAC systems where there is a lot of ducting and many spaces to serve. The CFM (cubic feet per minute) requirements at each destination of the ducts must be calculated to determine the pressure at which the air will exit the system after overcoming the resistances. The area of the outlet will vary depending on the distance the air had to travel from the blower. Once the air travels and expands, the pressure will be lowered. High Pressure Centrifugal Blowers create unfavourable environments for living creatures due to high pressures at the exact outlet of the blower. For this reason, custom blowers should be designed for each specific application.

Blower Impeller Types

The impellers on High Pressure Centrifugal Blowers have specifically designed blades for varying conditions. These types are Backward-Arched, Radial and Forward-Arched Radial tip.

Backward-Arched blades are aerodynamically designed to prevent dust or particle build-up on the blade during operation. They curve away from the direction of rotation as they extend from the eye of the impeller. They are strong and are perfect for high pressure applications.

Radial blades extend straight out from the eye of the impeller and are the simplest form. They are used for high pressure applications with nominal efficiency.

Forward-Arched Radial tip blades are arched towards the direction of the flow, and approach the circumference of the impeller at a 90 degree angle. This design provides high pressure applications without causing particles and debris to be trapped in the middle of the impeller.

High Pressure Blower Applications

These types of fans are well suited for corrosive, unclean air and exhaust fumes. This is why it is so important that the blades stay clean and operate at their full capability. High Pressure housings can be designed to split to facilitate easy access to the impeller for cleaning.  These High pressure housings are made from stainless steel or alloys and can handle up to 20,000 Pascals of pressure.

High Pressure Centrifugal Blowers are considered as heavy machinery and need to be tailor made for each application. The margin for error is small and the relevant professionals should be consulted. Custom Fans of Australia will be able to provide engineering information with numbers and values to determine how the high pressure centrifugal blower system will perform in your operation.
