The high-temperature-resistant LRK-MH cold smoke barrier is used to prevent the transfer of smoke and cold smoke.

It consists of a high-temperature-resistant plastic housing and a damper blade with a silicone membrane. The U-lip seals ensure a secure hold in the air duct.

The cold smoke barrier is air and smoke-tight against the direction of flow and prevents the transfer of cold smoke when used correctly. The preset magnet keeps the cold smoke barrier closed up to a differential pressure of approx. 10 Pa in the direction of flow. It is installed in the connection pipe of the exhaust or supply air opening according to the air direction.
