IRB
Duct fan suitable for clean or slightly polluted air with dust, for installation in round or rectangular air ducts.
The fan type IRE combines the advantages of an axial fan (simple and compact installation) with those of a centrifugal fan (higher capacity).
The fan can be installed outdoors or in a humid environment. The fan is then made suitable for outdoor installation.
The box is made of galvanised steel sheet & equipped with two equal connections for suction side and discharge side.
The centrifugal impeller, with backward or forward curved blades according to type, is directly coupled to the motor.
The IRB is available with AC or EC motor (0-10V).
