Thermex rattle-free damper Ø150 mm

Thermex Non-Clapping Damper is the ideal choice for those who want to prevent cold air from entering the ventilation system. This advanced backdraft damper is equipped with an innovative thermo-damper, which closes with three flaps held in place by magnets when the extraction is inactive. This creates two fully insulated air chambers that effectively prevent heat loss and ensure better energy efficiency than traditional solutions.Thanks to the magnets, annoying clapping from the wind is prevented, ensuring quiet operation. The damper fully opens even at low airflow, so steam and moisture are always reliably discharged. With a thermal insulating coating on the flaps, energy loss is further minimized.The Thermex Non-Clapping Damper can be installed both horizontally and vertically and fits all Ø150 mm wall ducts. It is easy to install by simply sliding it into the duct.Specifications:- Diameter: Ø147 x 77 mm- Material: Plastic and metal- Required opening pressure: >65 PaOptimize your ventilation with a non-clapping damper that combines efficiency, noise reduction, and energy efficiency.
