• The BR (back return plenum) is an effective way to introduce make-up air into the kitchen from the rear of the hood. The air is directed downward behind the hood through a sturdy, fully boxed plenum. Perforated panels inside the plenum distribute the low velocity air behind and below the cooking equipment. The make-up air is introduced in a way that does not affect the capture and containment of effluents, cooking surface temperatures or disturbing the gas equipments pilot lights. The back return plenum serves as stainless steel backsplash panels and provides the required clearance to combustibles for many installations. Back Return Plenums 4’ through 10’ lengths are constructed in one section, over 10’ in length are constructed in two sections. Back Return Plenums are ideal for mildly tempered or heated air, as the heated air will rise from the low discharge position and create a more comfortable kitchen environment. Larkin Industries Back Return Plenums are constructed of heavy gauge materials and built to provide years of service. All supply collars are 24” x 6” (1) per section.
