HUMIDITY SENSITIVE AIR INLET FOR ROLLING SHUTTER CASINGS
Flat design for perfect integration
With its flat design and its special airtightness sleeve, the EAH² air inlet is perfectly fitted to equip rolling shutter casings. Indeed, it is designed to offer optimized airflow and acoustic performance in combination with a roller shutter casing. The air is admitted in the room through the top of the product, the hole and shutter are not visible for the occupant. Its mechanical sensor modulates the airflow according to the local humidity, automatically and without electricity. This ability allows the air inlet to contribute to energy savings by reducing heat losses due to ventilation while ensuring excellent indoor air quality. An optional closing and opening device is available to manually fix the airflow to the minimum or maximum, if requested. A patented specific sleeve is proposed as accessory to increase the airflows of the standard versions. Whether you are in the individual house field or in the multi-flat field the EAH² is ideal for your hygro B ventilation systems.
Humidity sensitive system: modulates the airflow according to the local relative humidity rate.
Optional closing and opening device.
Vertical air jet for the comfort of the occupant.
Air admission hole and shutter not visible from the occupant.
Easy to maintain: no adjustment, simple yearly-dusting.
Easy to install, no visible screws.

Aesthetic integration
The flat and compact design of the EAH² and its non-visible top shutter favorites its aesthetic integration, especially when mounted on rolling shutter casings. Its single frame front cover makes the painting easy to adapt to colored casings or windows.
Humidity Sensitive Air inlet
Improved airtightness through efficient accessories
A common issue with rolling shutter casings, notably when in PVC, is that the slot drilled on its façade for ventilation generates lateral leakages through the cells. To avoid this issue we have developed a specific sleeve, the T-EAH², that ensures the continuity between the inner part of the shutter casing and the air inlet, optimizing the acoustic and aeraulics performance. A back seal (S-EAH²) is also proposed to adapt to specific shape of rolling shutter casing (light curve, unflat façade, etc.). This accessory is stuck at the back of the air inlet (self-adhesive seal).
Rolling shutter casings, but not only
Although first dedicated to rolling shutter casings, the EAH² can also equip windows with large top frames or transom windows.

Canopies As first dedicated for rolling shutter casings, the EAH2 does not require external canopy, the space between the shutter and the box of the rolling shutter casing being used as the outdoor slot for the incoming air. In the case of using a specific canopy, it must be validated that the aeraulics surface and its geometry are compatible with the slots and airflows of the air inlet.
Humidity sensitive air inlet for rolling shutter casings
Installed on the wall or on a rolling shutter casing, the EHT humidity sensitive air inlet is the ideal choice for air admission through the wall, and thus provides an alternative where lack of available space (on window frames) prevents the installation of window mounted air inlets.
Humidity sensitive air inlet for rolling shutter casings
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.
