The BRAL18 Series is a belt-driven, down-discharge rooftop supply fan designed to bring fresh outside air into commercial buildings. These units are commonly used in restaurants, warehouses, manufacturing facilities, and other commercial spaces where replacement air is needed to balance exhaust systems and improve overall ventilation.

Built with a heavy-duty galvanized steel housing, the BRAL Series is designed for long-term outdoor performance. Each unit features a removable cover for easier service access, a single-inlet supply blower, permanently lubricated bearings, and cleanable aluminum mesh filters to help protect the blower and improve air quality. The belt-drive design also makes future maintenance and part replacement more straightforward.
