    Warm air systems distribute the heated air through ductwork systems of supply and return air through metal or fiberglass ducts. Many systems use the same ducts to distribute air cooled by an evaporator coil for air conditioning. The air supply is normally filtered through air filters [dubious – discuss] to remove dust and pollen particles. [15]

    Metal baffles at the roof drain inlets reduce the injection of air which increases the efficiency of the system. [68] One benefit to this drainage technique is reduced capital costs in construction compared to traditional roof drainage. [66] Another benefit is the elimination of pipe pitch or gradient required for conventional roof drainage piping.
