Heating, ventilation, and air conditioning (HVAC) systems have plenums that connect to the HVAC system.
This is a vital function because it is designed to intake, distribute, and remove air. Typically, HVAC systems use two plenum boxes: a supply plenum and a return plenum.

How it Works

Using the HVAC’s ductwork, a supply plenum takes in the new cool or warm air from the heater or air conditioner and then distributes it throughout the building.

Return plenums take the used air and, via the ductwork, return it to the central HVAC system. The used air is recycled later as a fresh batch.

Among our products are plain plenums, lined plenums, and plenums with filter tracks.
