The unsealed damper is intended for the RT-08G, RT-08P, ZRP1 type controllers. It is used to supply air to the combustion chamber in fireplaces with a water jacket. The minimum gap around the damper wing ensures a minimum air supply, allowing the pressure differential to balance, and thus protects this type of cartridge against damage in the event of adverse weather conditions or power outages.

The sealed damper is designed for the RT-08OM, RT-08OS, RT-08SAC type controllers. It is used to supply air to the combustion chamber in Zdunski furnaces and air fireplaces. Due to the use and design of this type of furnaces, complete shut off of the air supply to the combustion chamber is required.
