DESIGN AND OPERATING PRINCIPLE

The fan casing is made of galvanized steel soundproof on the inside with 50 mm thick mineral wool.

The pivot design of the fold out motor-impeller unit ensures easy access to the fan internals for quick and efficient cleaning.

The inlet and outlet spigot diameters match standard duct sizes.

The spigots have rubber seals.

The fan is mounted on RN-KSK load-bearing frames with integral vibration dampers and mounting brackets KM-

KSK (purchased separately).

The fan benefits from a steel high-performance centrifugal impeller.

The impeller is mounted on the electric motor shaft and is jointly balanced statically and dynamically.

The high-performance single-phase or three-phase electric motor with a squirrel-cage rotor is completely maintenance-free.

The power is adjusted by means of transformer control units.

The fan is connected to power mains via the terminal box mounted on the electric motor.

Provide an additional electric cable length to ensure unobstructed opening of the fold out motor-impeller unit.
