Oblique air jet for occupant comfort

The oblique air jet of the EHA² skims the ceiling ensuring progressive heating of fresh air for the improved comfort of the occupants.

Optional opening and closing device

This device is available on versions 5-35 (humidity sensitive) and 35 (without humidity control); it enables the occupant to choose between three modes: minimum, automatic (humidity sensitive) or maximum airflow. The device can be added after the product is installed.

Efficient protection against external noise

When installed on its acoustic base and with acoustic external canopy (A-EHA), the EHA² air inlet offers great acoustic attenuation, up to 42 dB at maximum opening, which makes it one of the best products available on the market with an air cross section this size (3600 mm²).
