Cabinet
It is made of impact-resistant plastic, the colour is white. The fan is equipped with a reversible electric shutter.
Running wheel
is axial made of high quality impact resistant plastic. It has aerodynamically and performance optimised blades. The impeller is secured on the shaft by an anti-slip lock.
Motor
is asynchronous, with an external rotor and an auxiliary phase. The motor has grease-filled plain bearings for life. IPX4 protection. Double insulated design with thermal protection.
Flow direction
is from the impeller to the stator in the HV 150 type, the flow direction cannot be changed.
Clamping box
is accessible by removing the front grille of the fan. Connection by cable under plaster or after plastering. The terminal block includes a relief clip to prevent the cable from being pulled out.
Speed control
Continuous speed control is possible with the HV 150 AE type using REB 1 N or REB 1 NE. For Type A control, see Operating Modes.
Noise
The table shows the sound pressure values at the point (B - Fig. measurement of acoustic parameters), at a distance of 3 m, for a mounted fan. The table gives the correction values to obtain the LWA sound power at the mid frequencies of the octave bands for the intake (A) and discharge.
Mounting
is carried out in a single or double glazed window with a thickness of 3 to 25 mm. Using 3 screws, the fan can be mounted as a wall fan for supply or extract air through the wall. Installation is possible in walls with a thickness of 25 to 300 mm.
Instructions
The fans are suitable for short ducts with very low pressure drop or for ventilation directly through a wall or window. Fans can be used for ventilation in residential construction, public rooms, offices, shops and restaurants.
