Designed to be installed on the wall or on a rolling shutter casing, the EHT humidity sensitive air inlet is an ideal alternative to window-mounted air inlets. It thus solves the problem of lack of space on windows. With accessories, it provides a high level of acoustic protection, up to 52 dB attenuation. A closing device and an airflow controller can be used to protect from cold weather and strong winds.
Humidity sensitive system: modulates the airflow according to the local relative humidity.
Core drilling: easy installation on the wall, ideal for refurbishment projects.
Acoustic attenuation: up to 52 dB with accessories.
Easy to maintain: no adjustment, simple yearly dusting, and readily accessible filters.

Easy wall mounting and efficient protection against outdoor noise
Easy to install, in particularly in refurbishment, the circular hole can be made using a core drill 100 mm in diameter – 125 mm for the complete acoustic kit. The complete acoustic kit (EHT + 125 mm duct + acoustic foam + acoustic canopy) can attain an acoustic attenuation of 52 dB, which places it among the best products available on the market.
Insect filter
Nothing could be easier than cleaning the insect filter: once the EHT is unclipped, the removable F-EHT filter is readily accessible from the interior of the dwelling.
ACW: automatic airflow controller
The ACW makes it possible to limit the maximum airflow to 40 m3/h in a duct 100 or 125 mm in diameter, even when the pressure exceeds 20 Pa (when there is wind for example).

ACW Airflow controller: limits the airflow to 40 m3/h
The stylish design of the EHA² air inlet enables perfect integration on most windows or rolling shutter casings. With the inclusion of high efficiency acoustic foam the product reaches an acoustic attenuation of up to 44 dB when mounted with the special base and canopy. An optional device allows on demand manually closing or opening of the air inlet, complementing the humidity sensitive function available on the EHA².
