Non-electric acoustic, humidity-sensitive vent provides background ventilation
Suitable for use in applications where there are high levels of external noise such as near main roads, airports or railway lines. Ideal for social housing, student accommodation and hotels as it requires no user interaction.
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.
