Inline exhaust fans

Inline exhaust fan schematics are used for ventilation purposes. Ventilation is required in industrial zones as well as in homes. It is sometimes used for circulation of air and sometimes for the removal of existing air within a specified space. Exhaust systems are applied for the removal of air from chambers or rooms so that it can be replaced with the fresh air. This action could be performed for a number of reasons like to avoid the bad odor, to maintain the humidity level, to get rid of bacteria (or different micro organisms) or to keep the temperature level at steady conditions.

Exhaust Fan Categories

Exhaust fans are categorized on the basis of the installation of their drafting fans and their inducing or forcing drafting mechanisms. Inline exhaust fans are induced draft fans. This type of exhaust system includes the fixation of fan in between the duct. That is why they are known to be inline exhaust fans. This means that exhaust fan is situated within the duct. In other exhaust systems like ceiling fans and wall mounted exhaust fans the fan is located outside the duct.

Engineering principle of induction of air is applied in these fans. Induced draft fan means that these fans suck air from a chamber or room and push it outside the room or camber via ducts. Inline exhaust fans are used where there isn’t enough space for the fan to be installed. They also have application where one fan can work for the rest of others.

Inline Exhaust Fans Uses

Inline exhaust fans are versatile. One inline exhaust fan can perform an action that might take a number of lower powered fans. To remove vapors which have been accumulated inside the house or closed area, inline exhaust fans are used.

In the figure shown above, a fan is situated in between the duct path. It is not located outside the duct but after sucking the air from the room, and it sends it away towards an outlet. A single inline exhaust fan, similar to the designs that Custom Fans of Australia has, can also be used for the removal of air or vapors from multiple rooms. This can be achieved by setting up the inlets of multiple ducts in different rooms, making their junction at some point. Afterwards a high capacity inline exhaust fan should be installed in single duct (which is a joint venture of multiple small ducts). In this way a high capacity fan would suck the air from all of the rooms thus making a process more convenient and effective in terms of cost. An inline exhaust fan ca ben employed for ventilation purposes via single fan within two wash rooms.

So where you cannot install two fans, a single inline exhaust fan can serve the purpose. Usage of these fans is quite advantageous. They are easier to install and produce less noise as compared to other exhaust fan systems due to reduced vibrations. Their installation is within the ducts as shown in the schematics which provide them with enough support to be noise proof. The figure above provides multiple exhaust lines that a single fan can provide, a useful purpose instead of multiple fans. A single fan is enough for multiple exhaust points and is also cost effective. These fans are rated as continuous fans and have a long life span and some of them have life time warranties as well. Inline exhaust fans are installed with high a power motor which equips them in removing significant amount of air from a number of rooms including a kitchen as compared to other exhaust fans.
