EHA air inlet
Humidity sensitive, two-stream EMM air inlet
with the possibility of setting the diaphragm in the minimum flow position.
The EMM air inlet works automatically. It has a sensor (polyamide tape) that analyzes changes in relative humidity in the room. The higher the relative humidity, the more open the air inlet, the greater airflow into the room. The air inlet can be blocked in the minimum flow position. It is designed for installation in PVC, wooden and aluminium windows.
