Ventair Higroster Akustik

Profiled, two-stage damper ensures acoustic attenuation up to 43 dB while maintaining the rated flow of 28,4 m3/h.

Two stage acoustic attenuator of the Akustik air intake combined with Higroster controller effectively muffles sounds up to 43 dB while maintaining the nominal air flow of 28,4 m3/h.

Akustik Higroster is a two stage trickle vent controlled with both pressure difference and air humidity. Before the controlled air flow reaches your interiors, it first passes through a pressure controlled air intake and then through a humidity-controlled throttle. Throttle lever enables also manual control.

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!
