The series foresees models with 2,4 and 6 poles, three-phase and single-phase motors. The external rotor motor, perfectly speed controllable, is cooled by the airfl ow itself and does not exceed the dimensions of the fan casing. The impeller is single inlet forward curved.
The casing is flanged at both ends for simple duct fi tting. The electrical wirings are hosted in a suitable box placed outside the casing for an easy connection and accessibility. This series is suitable to convey clean air with a temperature range from -20°C to +40/70°C.
