Double speed centrifugal roof extractor


The main characteristic of this series is a special three-phase motor which allows the double speed feature by delta/star switching. The motor is outside the air flow, this allows the fan to exhaust clean or slightly dusty air also with grease and impuritiers with max. temperature up to 80°C (FC), 60°C(FCV. Therefore they are ideal for installation in kitchens, commercial and industrial buildings and wherever it is required the possibility of changing the performances and the noise level according to the needs. Available with horizontal outlet (FC) or vertical discharge (FCV).
