BLS 125 – Helios Fire damper stone
Fire protection ventilation tiles for the supply and extract ventilation of closed rooms and chambers to be protected against the spread of fire and smoke, such as e.g. installation shafts and cable ducts. They allow a constant, static air exchange which prevents heat accumulation in the closed chambers. The tiles can also be used as inflow openings in crucial corridor walls (emergency escape routes), unless the openings are in the lower wall area.
