CAF – Smoke damper
The CAF is an accessory for the BXC exhaust grille designed to protect dwellings from the smoke that might be propagated through the ventilation ducts in the event of a fire. When a fire breaks out, smoke may escape through the ducts to the lower stories (the upper stories are protected by fire dampers). The back-pressure then closes the CAF smoke dampers located in the dwellings on the lower stories, thereby preventing the propagation of the smoke. The CAF is specially designed for the BXC exhaust grille: its pressure loss is negligible and its operation is perfectly quiet.
