Luftmembran-D70, CMF FF, De Dietrich 86668046

The air diaphragm D70 CMF FF is a replacement part for gas burners and air handling units. It functions as a flexible membrane that controls air flow or pressure within the system. With a diameter of 70 mm, this diaphragm is designed to fit specific burner models. Over time, diaphragms can wear out or become damaged, leading to improper air-fuel mixture and reduced efficiency. Replacing it with this component helps restore correct operation and maintain reliable combustion in your heating equipment.
