The EAH humidity sensitive hygroscopied vent has been designed for use in SKT OPOTERM top mounted roller shutter systems and is compatible with all size roller-boxes, with or without fly screens.
Using the hygroscopied vent EAH allows to supply fresh air to the rooms. Even with the windows shut tight, it still allows to supply fresh air on a continuous basis, in amounts consistent with applicable regulations. The air inlet is controlled automatically and does not require power supply. When relative humidity varies, the device automatically controls the opening: the higher the humidity, the more the air inlet opens and a larger influx of air flows into the room.
The EAH Humidity hygroscopied vent satisfies the ventilation requirements set out in the Regulation of the Minister of Infrastructure of 12 April 2002 on the technical conditions to be met by buildings and their location. This regulation mentions, among others, the requirement of forcing (when appropriate) the circulation of air in buildings and is published in the Journal of Laws of the Republic of Poland.
