Fischbach High Efficiency Centrifugal Fans Sideview

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.
