When air is exhausted, or removed, from a building it is commonly replaced by use of air make-up units so that the air within the building is balanced. Double width backward inclined centrifugal fans (Models DQBCS, DQBCA, DBCA, DBCS) and also axial fans (Models JM, JMG) are used in make-up air units.
