Variflow Baffles
Optimizing the amount of exhaust air enters the core extractor slot is the key to the Spring AIR Systems system..

Spring Air accomplishes this complicated process with a unique core extractor profile that contains a series of specially
designed VARIFLOW baffles located along length of the core extractor. See Figure 25 above. The VARIFLOW baffles are
adjusted prior to shipment to allow the optimum amount of the air mixture to enter the core extractor slot. For instance
the VARIFLOW baffles located above a charbroiler are opened to the maximum 450 CFM/ft position and the VARIFLOW
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.
The VARIFLOW baffles are adjustable to provide between a 90 CFM/ft to 450 CFM/ft flow rate into the core extractor slot.
The VARIFLOW baffles are adjustable without any special tools by lifting off the core extractor removable insert one DD
type hoods (or removing the access door on water wash hoods) and hand adjusting the position of the baffle. Just set
the position of the VARIFLOW baffle to match the appliance located below. See Figure 25 for isometric view of
VARIFLOW baffles.
