Our free-wheeling centrifugal fans use the same principle as the centrifugal fans, but, as they do not have a housing, they can cover additional applications. They have a low exhaust velocity which results in an even, low-loss flow. They require less space and are easier to access for cleaning purposes. – Explosion-protected fans are executed and certified in accordance with directive 94/9/EC ATEX and, in the future, 2014/34/EU Volume flow500.000 m³/h Pressure 6,000 Pa Temperature 130 °C Output500 kW Miscellaneous Special material stainless steel
