EHT²

WALL HUMIDITY SENSITIVE AIR INLET

Consistency of aeraulic and acoustic performance

The EHT² is the new generation of humidity sensitive wall air inlet. Installed on the wall (100 mm or 125 mm), the humidity sensitive air inlet EHT² is an ideal alternative to window air inlets, offering an answer in case of lack of space on the windows. With accessories, it provides a high level of acoustic insulation, up to 52 dB, which places it among the best performing products on the market. The EHT² also has a multimodal dial where the closed mode allows protection from cold and strong wind. Are available as well the wide open and the humidity sensitive modes.

Aereco wanted to accompany its innovations on the EHT² with a new design in tune with the times. Indeed, the EHT² fits perfectly into the interior home by appearing space-saving and thin.

Flexibility for comfort

The EHT² has three possible openings for incoming air: two side openings and an opening above the device. By offering the choice of assembly according to the configuration of the room, the EHT² gives more possibility of wall installation. The EHT² can therefore be installed close to the walls without the risk of damaging them or bothering the residents because of the incoming air.

Clever insect filters

Clean the insect filter? It’s easy: the EHT² rotates and provides access to two types of removable filter. The F-EHT is easily accessible directly from the duct and the EHT² grid is even simpler from the base of the air inlet!

The rain canopy

The rain canopy has a protective parable that blocks raindrops, even in the most extreme conditions. Thanks to this canopy, almost zero infiltration! If water ever seeps into the duct, a inclined gutter drains the water and evacuates it without it being able to reach and soil the front wall.
