The fan is designed for transport systems of non-aggressive and non-explosive gases without pollution. Typical uses are:

  • pneumatic transport,
  • blowing in drying systems (e.g. graphic machines and processing of plastics),
  • air blowing systems in combustion / thermal treatment systems (e.g. melting furnaces).


  • radial high pressure fan with direct drive
  • riveted rotor made of aluminum sheet, with type B blades, dynamically balanced according to ISO 1940-1
  • die-cast aluminum housing
  • galvanized inlet cover
  • base welded from steel sheet
  • fan painted gray RAL7042 (in selected sizes engine painted in RAL 5010)
  • maximum temperature of the transported medium 80 ° C
  • motor ambient temperature from -20 ° C to + 40 ° C
  • figure LG270


  • asynchronous, three-phase, 230 / 400V, 100Hz or 400V, 100Hz (depending on the motor power)
  • insulation class F
  • degree of protection IP55
  • equipped with thermal protection PTC or PTC and TP depending on the model
  • FC version equipped with an independent cooling module

Special versions

  • any LG / RD figure
  • painting in a color other than the standard
  • rotor made of galvanized steel sheet
  • impeller made of stainless steel 1.4301
  • rotor made of acid-resistant steel 1.4404
  • motor with a different degree of IP protection
  • engine equipped with sensors or additional cooling
  • motor ambient temperature below -20 ° C and above + 40 ° C

Engine transducer

The converter supplying the motor must have the following U (f) classification:

where: U - rated voltage of the motor operation; f - frequency 100Hz

If the recommendations are not followed, the motor current increases disproportionately and the drive motor does not reach the rated speed. Under no circumstances should the frequency (rotational speed) be set higher than the 100Hz frequency stated on the nameplate, because the motor may be overloaded or the fan damaged due to too high speed.

The so-called boost, as this causes the drive motor to heat up too much. In order to protect the drive motor, a temperature sensor must be connected to the appropriate inputs of the converter.
