How To Buy
Product Features & Benefits
Heat Icon

Heating only make-up air

Since hot air will rise from its low discharge position and the majority of the air is drawn out as replacement air it will not affect capture and containment

Design Icon

Smart design

Supply air is introduced through the bottom of the plenum below the cooking equipment without affecting cooking temperatures, pilot lights or capture

Airflow Icon

Effective air distribution

Effectively introduces make-up air into the kitchen from the rear of the hood using a double layer of perforated panels, allowing for well-distributed, low-velocity airflow at discharge behind and below the cooking battery

Cleanliness Icon

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

Ease Icon

Easy installation

Simple, flexible installation

Energy Efficient Icon

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

Materials Icon

Material options

430 or 300 series stainless steel to match hood

Simplicity Icon

Insulation available
