blue_squareOur range of backward curved centrifugal fan units are efficient, robust, and quiet and driven by compact external rotor motors.

The units themselves are made from a centrally located motor fitted to either a plastic or metal centrifugal blade; there are a small number of long blades which are designed to push the air outwards which is the opposite purpose of a forward curved fan (FCI range). These units are often found in situations where a high pressure can be formed and the enclosure allows the air to be released in any direction.

The general sizes range from 133mm diameter up to 400mm. The motors are either 2 or 4 pole and normally are 230V however 110V and DC versions are also available (quantity dependant).
