Supply fans main purpose is to bring in a proportional amount of supply air to help in balancing the hood system out. Although it is not necessary to provide a dedicated supply fan with every hood system it helps to lessen the load on the building HVAC systems. Supply fans are configured to bring in a percentage of the air exhausted by the hood to keep the system requirements on the building HVAC to minimum. Each hood system requires a different percentage based on hood model, cooking load, and system design. Select Air Systems is able to help in determining if a supply fan and what type best suits the application.
