Back Supply Plenum

Back supply plenums are typically used in non-tempered or marginally tempered kitchen supply air applications. These plenums are ideal for heating air during the colder months since hot air will rise from its low discharge position and the majority of the air is drawn out as replacement air without affecting capture and containment.

Product Features & Advantages:

  • Effective Air Distribution - An effective way to introduce make-up air into the kitchen is from the rear of the hood using a double layer of perforated panels to allow for well-distributed low-velocity airflow at discharge behind and below the cooking battery.
  • Clearance to Limited Combustibles - Back supply plenums do double duty and function as a backsplash panel and provide the proper clearance to limited combustibles needed in many installations to meet NFPA 96 standards
  • Easy – Simple,  flexible installation
  • Energy Efficient - When using non-tempered air, utilizing low air velocities will keep the air near the hood where it serves as replacement air and is quickly exhausted.
  • Sizing - These plenums are 6 inches deep and stretch the entire length of the hood and discharges at 31.25 inches above the finished floor
