Stainless steel wall cowl with angled cap and back draught shutter
The D5G wall cowl from DEC INTERNATIONAL is a square external louvre with a fixed angled cap for the extraction of air in your ventilation duct. The back draught shutter in the grille will open in the event of overpressure. Furthermore, this valve helps to avoid a reverse air stream, as well as being resistant to water and wind.
The wall cowl is suitable for mounting on a round ventilation duct and is made of durable stainless steel 304/2B.
