Description
Light duty FCC (forward curved centrifugal) fans are commonly used for the transportation of clean air only in ducted systems. The fans can be placed in air handling units or a plenum attached to several metres of ducting.
The FCC fan is almost always preferred in clean air applications mainly because of cost. While the BCC (backward curved centrifugal) fan is a more efficient performer, the FCC is considerable less expensive but has its limitations.
Sizes range from 250mm to 1000mm. The larger units are normally mounted on a base while the smaller range has a ‘cubic’ frame to support the motor or in some cases the motor can simple be ‘piggy back’ mounted on the fan.
These fans are always belt driven which allows for a very large scale of various permutations for both volume and pressure. Changing pulley diameters can deliver any required volume and pressure within the speed limitations of the fan.
