Used to regulate the draft by partially or completely closing the flue, as well as facilitating the exhaust of smoke from the heating appliance. It can also be used as a valve to prevent the escape of warm air from the room.
An insulated rotary damper, also called a throttle valve, a flue damper, is an element of the flue system that is used to regulate the draft by partially or completely closing the flue by turning it mechanically with a handle, as well as facilitating the escape of smoke from the heating appliance. It can also be used as a valve to prevent the escape of warm air from the room when the flue is not actively used. Safe and convenient to use, as well as marked with the CE mark and complies with the current European Union standard requirements.
Double-walled construction with basalt stone wool insulation between the inner and outer parts protects the pipe from cooling and condensation. The inner wall is made of stainless, acid and heat-resistant steel. Its thickness is not less than 0.5 mm, which makes the structure durable and safe.
