HCFB/4-355 H IP65 axial fan

Cabinet

It is made of steel sheet, coated with black lacquer, the screws are electroplated.

Running wheel

is made of glass fibre reinforced thermoplastic. The impeller is statically and dynamically balanced.

Motor

is asynchronous, black lacquer finish, stator with cooling fins, thermal protection of windings, insulation class F, operating temperature -40 to +70 °C. Lifetime grease-filled ball bearings. IP65 protection.

Speed control

is carried out by electronic or transformer regulators by changing the voltage, for three-phase types by frequency converters.

Rotation direction

can be changed for both single-phase and three-phase motors. With a standard impeller, the flow rate drops by approx. 30% when the direction of rotation is reversed. With the wall-mounted version, the air flow from the motor to the impeller is standard.

Clamps

It is made of black plastic, single phase design has a start-up capacitor. The terminal block is located on the motor (wall mounted version).

Mounting

Fan in each motor axis position. The enclosure must not transmit mechanical stresses from the building structures.

Noise

emitted by the fan is given in the tables, the measurements being made at a distance equal to three times the impeller diameter (but not less than 1,5 m) in the free acoustic field.
