  • degree of protection IP55
  • insulation class F
  • adapted to frequency regulation
  • motor ambient temperature from -20°C to +40°C

CONSTRUCTION

  • medium-pressure radial fan with direct drive
  • steel sheet impeller with backward tilted blades, dynamically balanced according to ISO 1940-1
  • housing is welded from steel sheet
  • fan painted blue RAL 5010 (corrosivity category C3)
  • maximum temperature of the transported medium 80°C
  • figure LG270

SPECIAL EXECUTIONS

  • optional configuration LG/RD
  • color other than standard
