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,
oering 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
Flexibility for comfort (1)
The EHT2 has three possible openings for incoming air: two side openings and an opening
above the device. By oering 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 (2)
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 (3)
The rain canopy has a protective parable that blocks raindrops, even in the most extreme
conditions. Thanks to this canopy, almost zero infiltration. Aereco wanted to accompany its
innovations on the EHT2 with a new design, clean and in tune with the times. Indeed, the EHT2
fits perfectly into the interior home by appearing space-saving and thin.
