Protection for your ventilation system
The ventilation mushroom is the perfect accessory for the AlphaAir Freshbox 25 ventilation System and its variants. Pipes of systems that ventilate rooms below ground level often lead from basement windows into light shafts. There, a mounted ventilation mushroom prevents the stale air from being drawn back in through the upper fresh air pipe. In addition, the ventilation system is thus also protected from penetrating rain and dirt.
This ventilation mushroom fits all 50 mm pipes.
