High Efficiency Centrifugal Fans – HE/HD Series

HochleistungsgebläseHochleistungsgebläse

Fischbach high efficiency fans distinguish themselves by compact design with internal motor combined with high volume flows up to 40.200 m³/h and can therefore replace many standard fans with belt drive. Typical ventilation applications include the fields of industry, suction and clean room technology.

High Efficiency Centrifugal Fan HE 350-450

Robust housing made of galvanized steel. Efficiency optimized impeller made of Aluminium and with backward curved blades.

  • Driven by a FISCHBACH disc rotor motor
  • speed 0…100% adjustable by voltage or by frequency-converter
  • Motor protection class IP 65, insulation class F (155°C), protected by a thermal contact.

The aggregate is vibration damped by rubber-metal-connections on the Motor axle for very silent running.

High Efficiency Centrifugal Fan HDE/HD 350-450

Robust housing made of galvanized steel. Consisting of 2 HE fans connected together. The fans fit through standard doors, because they can get connected locally and may be controlled separately. Efficiency optimized impeller made of Aluminium and with backward curved blades.

  • Driven by a FISCHBACH disc rotor motor
  • speed 0…100% adjustable by volage or by frequency-converter
  • motor protection class IP 65, insulation class F (155°C), protected by a thermal contact.

The aggregate is vibration damped by rubber-metal-connections on the motor axle for very silent running.
