The fan is radial with backward curved blades. It is made of aluminium sheet and is statically and dynamically balanced.
Square box
with a revision switch, it is located on the base (CRHx) or housing (CRVx) of the fan. For single-phase fans, the terminal block also contains a start-up capacitor. The protection rating is IP55.
Motor
It is asynchronous with shorted resistance armature, with external rotor. The motors are equipped with a thermal fuse as standard. CRH(V)B fan motors are 1-phase for 230 V, CRH(V)T are 3-phase for 230/400 V. The windings are tropicalised with class F insulation. Protection rating IP54.
Speed control
is carried out by changing the voltage by electronic or transformer regulators, three-phase types also by frequency converters.
Rotation direction
is only possible in one direction, as indicated by the arrow on the fan housing. The opposite direction of rotation can cause motor overload, and the fan will also experience increased noise.
Mounting
