Features

• Automatically adjusts according to outdoor temperature. The bimetallic thermostat regulates the vent flap opening between +10°C and -5°C. At colder temperatures, a minimal opening of just a few millimeters ensures sufficient and draft-free ventilation.
• The minimum opening can be adjusted according to installation conditions and can also be manually closed if needed.
• The unique efficiency of the filter made from 3M Filtrete™ material is based on its fibers being electrically charged. The electrically charged filter attracts and tightly traps even microscopic particles like a magnet. According to VTT research, the filter removes 100% of pollen and significantly reduces exposure to health-hazardous fine particles.
• 10-year vent warranty
• The vent’s sound attenuation class is Dn,e,w 37 dB according to SFS-EN ISO 717-1.
