Aerauliqa QD ventilation fans have a contoured design, a housing and front panel made of anti-break and UV resistant ABS plastic. It is characterized by a lower noise level (34 dB) compared to its counterparts with similar performance and traditional design. Its front panel can be easily removed without tools, so the fan can be cleaned quickly and easily.

Thanks to the integrated butterfly valve, unwanted backflow can be prevented and the inflow of cold air into the ventilated room can be reduced. The springless design of the butterfly valve results in lower flow and pressure loss for even more efficient operation. If it is not needed under the given installation conditions, it can be easily removed from the fan without tools for an even lower noise level.

The high-quality roller bearing built into the device, designed for 30,000 operating hours, ensures a long service life and enables installation on both the side wall and the ceiling.

Timer function: when the fan switch is turned off, the ventilation does not turn off immediately, but only a few minutes later. The delayed switch-off (post-ventilation time) can be set between 1-25 minutes according to user needs. This function can be especially useful in the case of ventilation of restrooms or bathrooms combined with a restroom.

Tested according to the latest standards: at Aerauliqa, the units are tested in a laboratory certified by TÜV Rheinland, that is, accurate, up-to-date measurements are made regarding electrical safety, reliable performance and noise level data are indicated. The design and production are carried out in accordance with EN60335-2-80 (low voltage directive) and EMC (electromagnetic compatibility) directives.
