Motor
is asynchronous with short armature, external rotor and starting capacitor, black lacquer finish. The motors are equipped with thermal protection as standard, the windings are tropicalised with class F insulation and an operating temperature of -40 to 40 °C. Grease-filled ball bearings for life. IP54 protection.
Speed control
is carried out by electronic and transformer regulators by changing the voltage or frequency converters.
Rotation direction
cannot be changed.
Square box
is made of black plastic as standard. In the single-phase version it also contains a start-up capacitor. The terminal block is located on the cabinet.
Mounting
Fan in each motor axis position. The cabinet must not transmit mechanical stresses from the piping. A flexible connection to the piping must be used.
Noise
indicated in the performance characteristics correspond to the free-field sound pressure values at a distance of three times the impeller diameter (minimum 1,5 m).
Instructions
