Return Air Plenums
As a furnace operates and blows out air, it must at the same time return to it that same amount of air. A return air plenum is the ducting that is attached to a furnace for that return air to flow through, and is used as a central manifold for other return air ducting.
Your order will also include Alpine's exclusive free instructional video on DVD! Watch as a pro quickly assembles the return air plenum, and shows you how to do the same. You'll have all your questions answered as you see how fast and extrememly easy it is to put together. Plenum assembles in about 5 minutes.
NOTE: Return air plenums are only available for purchase with equipment orders- such as furnaces, heat pumps or air conditioners - since their packaging requires they be delivered on a pallet.
