RKB
Duct fan suitable for installation in rectangular air ducts.
The fan type RKB combines the advantages of an axial fan (simple and compact mounting) with those of a centrifugal fan (higher capacity).
The box is made of galvanised steel sheet and has two equal connections for the suction side and the pressure side.
The centrifugal impeller in galvanised steel sheet, with backward-curved blades, is directly coupled to an external pole motor (protected by integrated thermo-contact in the motor windings).
The RKB is available with AC or EC motor (0-10V).
