Ventair TRDn Akustik

Precise automated control using pressure difference and with acoustic attenuation up to 48 dB.

Two stage acoustic attenuator of the Akustik air intake combined with TRDn controller effectively muffles sounds up to 48 dB when closed. With automated pressure difference control, Ventair TRDn Akustik ensures an optimum, healthy climate inside your house, while minimizing energy consumption as far as possible.


Listen to the silence

Acoustic air intake designed to be virtually noiseless. It muffles almost all external noise, letting only the air in, much more air. To achieve this result we had to use every inch inside the Akustik air intake. We designed an attenuator with a precise profile, which perfectly fits the aluminium housing.

Less is more

A unique combination of high flow and perfect acoustic attenuation makes it possible to use less trickle vents, while maintaining optimum operation of the ventilation. Less trickle vents means better acoustic attenuation and higher savings. That’s simple!
