Make-Up Air System

A make-up air unit is a critical but often overlooked component of any high-volume kitchen ventilation system. When exhaust fans extract large volumes of air from the kitchen, negative pressure builds up — causing kitchen doors to be hard to open, drawing exhaust gases back in from other outlets, and making the exhaust system work harder and less efficiently. Apollo supplies and integrates make-up air units that introduce fresh tempered air into the kitchen space at the same volume as the exhaust — maintaining neutral or slight positive pressure. This ensures the exhaust system operates at rated efficiency, reduces energy consumption and keeps the kitchen comfortable for staff throughout the service period.
