Cabinet
It is made of steel sheet, coated with black lacquer, mounting brackets and screws are electroplated.
Running wheel
is made of aluminium alloy. The rotation of the blades is set by the manufacturer. The impeller is statically and dynamically balanced.
Motor
It is asynchronous, depending on the type with shorted resistance armature, stator with cooling fins. Motors with resistive armature are equipped with thermal protection (thermocontacts or PTC), the winding is tropicalised with class F insulation and operating temperature -40 to +40 ˚C. Grease-filled ball bearings for life. IP55 protection.
Speed control
is performed by a frequency converter.
Rotation direction
can be changed for single-phase and three-phase motors. With a standard impeller, the flow rate drops by approx. 30% when the direction of rotation is reversed. It is possible to order an impeller for the opposite direction of rotation. Air flow is standard from the impeller to the motor.
Clamps
is made of black plastic as standard. The terminal block is located on the casing.
Mounting
fan in each position of the motor axis. The housing must not transmit mechanical stresses from the pipework. 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
The COMPACT series fans are high-performance fans with a convenient short housing for installation in the ductwork.
