Diermayer Flue gas damper MOK 250 motor-controlled

Motor-driven flue gas damper with actuator to control the flue gas opening in oil and gas fireplaces as well as in solid fuel stoves, especially in systems with pilot flame or minimum opening for negative-pressure flue gas systems. The housing and damper parts are made of high-quality stainless steel and the integrated sealing membrane is made of EPDM.

Thanks to the motorised actuator, the damper opens already before the burner is started up, thus preventing flue gas build-up. In solid fuel appliances, the damper ensures efficient combustion in conjunction with the stove control. When the heating system is not in use, the damper closes automatically and prevents the loss of heat and heated room air.

In cascade systems, the motorised flue gas damper prevents flue gases from escaping or flowing back by closing all unused fireplaces. The patented mechanism ensures a high level of operational safety and a long service life, regardless of the installation position. In addition, the functionality can be checked at any time by manual operation.
