HCBT/4-710 H IP65 axial fan

Cabinet

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

Running wheel

is made of Al alloy. The impeller is statically and dynamically balanced. The rotation of the blades is set by the manufacturer.

Motor

is asynchronous, depending on type with short armature, stator with cooling fins, lacquer finish. The motors are with class F insulation and operating temperature -40 to +70 °C (type HCBT/4-710 H -40 to +55 °C). IP65 protection.

Speed control

is carried out by transformer regulators by changing the voltage or by frequency converters.

Rotation direction

can be changed. With a standard impeller, the flow rate drops by approx. 30% when the direction of rotation is reversed. The air flow is standard from the motor to the impeller.

Clamps

is made of black plastic as standard. The terminal block is located on the engine.

Noise

emitted by the fan is tabulated, measurements are taken at a distance equal to three times the impeller diameter (but at least 1.5 m) in the free acoustic field.

Mounting

of the fans at each position of the motor axis.
