The REV LOW accomplishes this complicated process with a unique core extractor profile that
contains a series of specially designed VARI-FLOW baffles located along length of the core
extractor. See Figure 3 above. The VARI-FLOW baffles are adjusted prior to shipment to allow
the optimum amount of the air mixture to enter the core extractor slot and thereby minimize roll
back into the hood canopy. For instance the VARI-FLOW baffles located above a Charbroiler are
opened to the maximum 450 CFM/ft position and the VARI-FLOW baffles located above ovens or
steamers are closed to the minimum 90 CFM/ft position. This variable adjustment along the
length of each hood provides an exhaust system that truly minimizes the amount of exhaust air to
properly ventilate any kitchen line up.
