Fans designed for transporting non-aggressive and non-explosive gases. Typical applications:

  • pneumatic transport,
  • blowing in drying systems (e.g. graphic machines, processing of plastics),
  • air blowing systems in combustion / thermal treatment systems (e.g. melting furnaces),
  • for air transport in ventilation systems and technological lines,
  • dust content in the transported medium up to 1g/m3.


  • low-pressure, single-sided, direct-driven radial fan
  • impeller welded from black steel sheet, backward curved blades welded from carbon steel sheet, painted with primer paint, balanced according to ISO1940-1
  • housings welded from carbon steel sheet
  • fans are normally painted in blue RAL5010, corrosivity class C3
  • transport of a medium in the temperature range -20°C to +80°C
  • standard figure LG270


  • asynchronous 3-phase 230 / 400V, 50Hz (power up to 3,0kW)
  • aasynchronous 3-phase 400 / 690V, 50Hz (power from 4,0kW)
  • IE3 efficiency class
  • degree of protection IP55
  • insulation class F
  • adapted to frequency regulation
  • motor ambient temperature from -20°C to +40°C


  • anti-vibration inlet and outlet connections
  • support frame
  • inlet and outlet covers
  • connectors, reducers, adapters
  • vibro-isolators


  • any LG or RD figure
  • painting in a color other than the standard one according to the RAL palette

  • galvanized housing and impeller
  • housing and impeller made of stainless steel 1.4301
  • housing and impeller made of stainless steel 1.4404
  • for transporting a medium with a temperature below -20°C and above +80°C
  • for work in potentially explosive atmospheres in zone 1 or 21 or 2 or 22
  • with clutch drive
  • with belt drive
  • with thermal and acoustic insulation
  • with a motor for a voltage or frequency other than the standard
  • with a motor with a different IP protection class
  • with a motor with a different insulation class
  • with a motor equipped with sensors or additional cooling
