VENTAIER air diffusers

Product descriptionTechnical dataDocumentation

VENTAIR

The Ventair range of tried-and-tested products has been expanded with a new acoustic solution – the Ventair Akustik air intake – an exceptional combination of high airflow and excellent sound attenuation.

Ventair Akustik dampens annoying noises whilst supplying the right amount of air to the interior. All this happens automatically and imperceptibly, and all you hear is the result – the silence you’ve been dreaming of. Thanks to its high efficiency, this new solution allows for the use of fewer air outlets whilst maintaining proper ventilation. And the fewer air outlets, the better the noise reduction and the greater the savings.

Ventair Higroster Acoustic

The new Akustik acoustic air intake is made from high-quality materials, predominantly aluminium. Thanks to its two-stage acoustic silencer, the Ventair Higroster Akustik reduces noise by up to 44 dB whilst maintaining an air flow rate of 28.4 m³/h. When combined with the Higroster humidity-controlled regulator, the Ventair Akustik forms a dual-system air diffuser – a device controlled automatically by both air humidity and pressure differential. The Ventair Higroster Akustik air diffuser can also be controlled manually.

Ventair TRDn Acoustic

The Ventair TRDn Akustik acoustic air vent has been designed for those who value peace and quiet. The best sound insulation ever achieved in a window ventilator is the result of combining the reliable Ventair TRDn controller with the two-stage sound attenuator of the Ventair Akustik intake. Automatic pressure differential control delivers the right amount of air to your home and also significantly reduces heat energy consumption.

Higroster Ventair

Higroster is a humidity-controlled air diffuser. A small hygrometer measures the relative humidity in the room and automatically adjusts the air flow to suit the humidity level. Ventair Higroster air diffusers are made from exceptional materials, such as aluminium, high-quality ABS/ASA and glass fibre composites. This makes them more durable and ensures they retain their properties over time. Ventair Higroster is the only humidity-controlled diffuser on the market with an aluminium body. Its well-thought-out design allows the hygrometer to be removed during installation and cleaning to prevent damage to the unit.

TRDn

Thanks to its precise control of the pressure differential, the Ventair TRDn automatically supplies the correct amount of air to the interior, whilst significantly reducing the amount of heating energy required to heat the rooms.

The use of an aerodynamically shaped aluminium blade helps to stabilise the airflow. The higher the pressure, the higher the blade rises, thereby limiting the increase in the airflow. All this happens automatically. In addition, you can increase or decrease the air flow yourself at any time using the manual controls.

Simpress

Ventair Simpress is the only Brevis diffuser whose body is not made of aluminium, but of high-quality ABS/ASA. The use of high-quality plastic means that the Simpress offers excellent resistance to freezing.

Thanks to its automatic pressure control, the Ventair Simpress automatically supplies the correct amount of air to rooms whilst reducing heating energy consumption. Its tried-and-tested design, similar to that of the Ventair TRDn diffuser, offers all the benefits of the economy version.
