Supply panel replaces the standard louvered panel which supplies A.C. cold air at a 45 degree angle, mixing cold air with hot air. Our panel supplies a concentrated stream of cold air from your central HVAC system, to the floor, driving the hot air to the ceiling(hot air rises). The 6" duct is reduced to 4",at the panel, to increase the speed of the cold air,to the floor. The damper is closed during the winter months to stop heated air. Extending the life or eliminating the need for an extra A.C. unit. HVAC ceiling panels should be installed on the perimeter, away from the Hot Air Axe, driving the warmer air up, to be exhausted by the Hot Air Axe.
