Lennox 64L81 Air Flapper Pack Of 10

The Lennox 64L81 Air Flapper pack of 10 is a replacement part in Lennox HVAC systems. Air flappers, or air diaphragms, are usually a flexible membrane that changes with the pressure of the air. This movement blows conditioned air through vents all over your home so that the temperatures can be well-regulated. Replacing worn-out or damaged air flappers can enhance the flow of air in your home, may lead to a reduction of energy bills and enhance the efficiency of your Lennox HVAC system.
