Supply panel replaces the standard louvered panel which supplies A.C. cold air at a 45 degree angle, mixing cold with hot air. Our panel supplies a concentrated stream of cool air from your central HVAC system, to the floor, driving the hot air to the ceiling. 8" duct is reduced to 6" to increase speed of cool air. Damper closes off the supply of hot air in the cold months. Extends the life on your extra A.C. unit. Moves the cool air to the floor, creating a up flow of hot air to be exhausted by the Hot Air Axe. These panels should be located at the perimeter of the server room,away from the Hot Air Axe.
