Supply Air Plenum

Introduction to Supply Air Plenum

AXENIC SYSTEMS (established in 1995) provides supply air plenum for forced-air heating, ventilation and air conditioning system depends on a system of ducts to provide a controlled path for distributing heated or cooled air throughout the home. Typically, HVAC duct systems are made of sheet metal, but other rigid heat proof materials such as fiberglass or insulated plastic may be used. Regardless of construction material, the heart of an HVAC duct system is the plenum.

The Supply Air Plenum is an air distribution box. It’s mounted directly to the supply outlet of the HVAC equipment–that is, the outlet that discharges chilled or heated air into your home. The air ducts that dispense the air into the individual rooms of your living space all connect to this plenum. The HVAC equipment has a blower that forces cooled or heated air into the supply plenum and from the plenum into the rooms through the supply duct system. Air-cleaning filters may be located in the supply plenum.


  • Supply Air Plenum distributes air consistently and silently, making them perfect for areas with high-traffic or sensitive environments.
  • Beneficial for cooling purposes since they can help pull heat away from the area being cooled.
  • Supply Air Plenum helps decrease humidity levels and creates a more comfortable environment for the cleanroom.
  • Prevent dirt and other fragments from getting into the HVAC system and into the cleanroom.
