Product description

Air circulation

  • Moving air improves the growth of plants. It is extremely important for their health and a balanced culture area.
  • It reduces air humidity in the culture area.
  • This prevents fungal attacks and rotting as well as damage to the flowers and the flowers falling off.
  • Air circulation widely reduces damage caused by botrytis or grey scale and enhances the stem quality of cut flowers.
  • A uniform temperature distribution simultaneously reduces costs for personnel, heating and pesticides.


  • Duct sleeve made of galvanised sheet-steel, with synthetic resin varnish.
  • Mounting lugs for suspension from the roof construction.
  • With protective grilles on both sides, protection against accidental contact in accordance with DIN EN ISO 13857.
  • 8-blade plastic impeller.

Air flow direction

  • Airstream and rotational direction are marked by arrows on the duct sleeve.


  • Asynchronous motor.
  • Reversible.
  • Thermal overload protection as standard feature.

Electrical connection

  • Ready for connecting with a 2 m flexible connecting duct with plug.

Special versions

  • The following special versions are available at extra cost on request:
    • Special voltages and frequencies.
    • Single-phase motors with thermal contacts or PTC thermistor, with potential-free terminal connections.
    • Fans with enhanced anti-corrosion protection.
  • Information on operation at temperatures occasionally below -20°C available upon request.
  • If operating with frequency converters, the factory must be consulted.
  • Feasibility must be checked in each case.
