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.
