EC version: Energy-saving, quiet and with a brushless motor controllable in a wide range.

With the help of Aerauliqa QBM ventilation fans, extremely quiet ventilation can be achieved by not placing the unit in the wall or ceiling of the ventilated room. In general, it is recommended to install it above a false ceiling, in an attic, or in other places where the noise level resulting from the operation of the fan is less disturbing to the user. The fan housing is made of sound-insulated, galvanized steel sheet, the fan unit placed in it has a long-life, maintenance-free rolling bearing and built-in thermal protection. The top cover of the device can be easily removed, which facilitates cleaning and maintenance of the fan.

Designed for ventilation through longer pipe sections, with a high-efficiency, forward-bladed radial impeller.
The performance of the fan (along with its air delivery and noise level) can be adjusted in a wide range according to the user's needs with the Aerauliqa CTRL-M type external control unit (optional accessory).

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.
