Design 47 Vane Axial Adjustable Pitch Fans are used in applications where demands vary with system or seasonal change. Blade pitch is manually set to increase or decrease performance. Blades are easily adjustable externally at the hub. Available in compact direct drive models.
Fan cases are fabricated from heavy gauge sheet steel with roll formed flanges on inlet and outlet. Cases include 9 stationary guide vanes. Impeller blades and hubs are of pressure die cast A356-T51 aluminium alloy. Blades are aerofoil design shaped for maximum efficiency and twisted from hub to tip to obtain equal air distribution along the blade.
