Application

 

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.

CONSTRUCTION

  • 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

MOTOR

  • 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
