Description
The Glidevale Protect range of Fresh wall ventilators has been specifically designed to introduce fresh air into our homes in order to control condensation, and being non-electrical they use no energy to operate. The vents direct the air flow from around the centre of the room to effectively disperse it. The Fresh 99H and acoustic model 99HdB are humidity-sensitive, making them fully automatic, requiring no user interaction. Non-electrical, non-mechanical humidity-sensitive through wall vents provide controllable, responsive background ventilation. Supplied as automatic internal vent, ducting and external grille.
Features and Benefits:
- Automatic opening / closing dependent upon relative humidity (RH).
- Energy saving through reduced heat loss.
- Operating range 35% to 75% RH.
- Trickle facility even when ‘closed’ to ensure fresh air ingress.
- 99HdB model offers sound reduction up to 40dB Dn,e,w.
- Ventilation equivalent area of 3930 mm².
