Centrifugal fan-KEF

Application

Fans for ventilation applications. This fan type is used in the following areas, among others:

  • Ventilation technology
  • Air-conditioning technology
  • Ventilation and deaeration systems
  • Compressed air technology
  • etc.

Construction

Direct-driven centrifugal fan. Housing in steel construction. Impeller with forward curved blades made of steel. All surfaces painted or coated in RAL 5010 / corrosion protection class C3.

Drive

We offer a wide range of different electric motors, all of which comply with the current standards in terms of efficiency.

  • IEC standard motor
  • Asynchronous, single-phase, 230V, 50Hz (up to 1.5 kW)
  • Asynchronous, three-phase, 230/400V, 50Hz (up to 3.0 kW)
  • Asynchronous, three-phase, 400/690V, 50Hz (from 4.0 kW)
  • Efficiency class IE3
  • Protection class IP55
  • Insulation class F
  • Designed for frequency converter operation
  • Motor ambient temperatures from -20°C to +40°C

z (ErP, CE) are met or exceeded. They are built according to IEC 60072 as well as IEC 60034 and IEC 60034 and have a CE mark. The standard version includes: Three-phase motor (asynchronous) 220-240/380-420V (50 Hz frequency) or single-phase motor 220-240V (50Hz frequency) with a capacitor, insulation class F, protection class IP55. On request, we can supply electric motors with a different frequency (e.g. 60Hz) or voltage, a higher protection class or adapted voltage control. Other accessories include frequency converters for infinitely variable speed control, bimetal sensors and posistor sensors.
