EHT Air Inlet

The efficient wall mounted alternative.



Installation Manual


The efficient wall mounted alternative

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.

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).
