Centrifugal fan casing with an insulation of 50mm, equipped with an EC motor, comforme directive ErP2018.
The fan casings are equipped with a plug fan and an EC motor 230V 1~ with an integrated thermal protection with auto restart. The backward curved impeller is made out of PA66 plastic reinforced with glass fibre. The fan has a protection class IP44 and an insulation class B, the fan casing has a connection box IP55. The motor’s velocity can be regulated by means of a 10kOhm potentiometer or an external signal 0-10V, which can be connected directly onto the terminal block.
The casing is made out of galvanized steel, acoustically insulted on the inside with 50mm mineral wool insulation. The insulation is provided with a protection film, so that the insulation material cannot end up into the air flow.
