GRAVITY BACK DRAFT DAMPER

ser gra

Manufactured from chemical resistant rigid PVC. It allows air only to flow in one direction through the duct system. When the fan is switched off the gravity non return flaps prevent air from re-entering the fan system and contribute to reducing heat loss. Connections are female socket one end and male spigot the other end.
