Running wheel
The impeller is made of sheet steel, the shape is specially optimized for maximum flow and pressure with minimum noise. The impeller is pressed directly onto the motor.
Motor
The motor is an asynchronous motor with auxiliary phase in external rotor design. The motor has grease-filled ball bearings for life. Protection IP44. Design with double insulation and thermal protection.
Flow direction
Flow direction is from stator to impeller.
Clamps
The terminal block is located on the motor, in the case of a TREB wall-mounted fan, the cable from the terminal block is routed through a rubber grommet in the wall of the fan housing.
Speed control
Speed control is carried out by electronic or transformer regulators by changing the voltage.
Noise
The noise emitted by the fan is measured at a distance of 1.5 m in the axis of the fan on the suction side.
Mounting
Fans are mounted in each position of the motor axis.
Instructions
The fans are suitable for short ducts with very low pressure drop or for direct through-wall ventilation. Fans can be used for ventilation in residential construction, public rooms, offices, shops.
