short description
Centrifugal duct fan, DN 250, alternating currentProduct description
Special features
- Efficient centrifugal duct fan made of powder-coated sheet steel.
- Suitable for industrial and residential installations.
- Centrifugal impeller with backwards curved blades.
- Quiet and powerful.
- Reduced space requirement due to compact dimensions.
- For direct installation between ducts, for ventilation or air extraction, depending on the installation position.
- Round connection sockets on inlet and outlet side adapted to standard ducts.
- Mounting foot available as accessory.
Air flow direction
- Airstream and rotational directions are indicated by arrows marked on the fan housing
Motor
- Single-phase AC motor.
- External rotor capacitor motor.
- Operating capacitor in the terminal box is ready to be connected.
- Speed-controllable.
- Thermal overload protection (temperature sensor in motor winding) as a standard feature.
- The overload protection automatically switches the fan off in the event of overheating.
- Robust motor with ball bearings, maintenance-free.
- IP X4 degree of protection when installed in ventilation ducts with at least 1 m of duct on the inlet and outlet sides.
Installation information
- Can be fitted in any position.
- Use optional ELR flexible cuffs to prevent transfer of vibrations to the duct system.
Electrical connection
- Externally fitted terminal box with cable guide bushes.
Safety information
- 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 an optional SGR protective grille.
