short description

Centrifugal roof fan, DN 200, low energy consumption, alternating current

Product description

Features

  • Centrifugal impeller with backwards curved blades.
  • Inlet and outlet side connection couplings for direct installation in ventilation ducts.
  • Mounting foot available as accessory.

Air flow direction

  • Airstream and rotational direction are marked by arrows on the terminal box.

Motor

  • External rotor-capacitor motor.
  • Operating capacitor in the terminal box is ready to be connected.
  • Speed controllable.
  • Thermal overload protection as a standard feature.
  • Robust motor with ball bearings, maintenance-free.
  • IP X4 degree of protection when installed in ventilation ducts with at least 1 m ducts on the inlet and outlet sides.

Mounting instructions

  • Can be fitted in any position.
  • Use ELR flexible cuffs to prevent transfer of vibrations onto the duct system.

Electrical connection

  • Externally fitted terminal box with cable entry grommet.

Safety instructions

  • The fan may be operated only if the protection against accidental contact with the impeller is guaranteed to be in accordance with DIN EN ISO 13857 for fans with free inlet or outlet. To do this, fit a SGR protective grille.
