Roof Mounted Belt Drive Downblast Exhausters/Ventilators are designed to exhaust air out of commercial and industrial buildings. All models are for roof mounting only. Motor and wheel are easily detachable without removing Exhausters/Ventilators from curb. Permanently lubricated ball bearings (5BDD10 – 5BDD13) and regreasable pillow block bearings (5BDD15 – 5BDD24). Welded curb cap corners eliminate water entry into ducts or building. Ball bearing motors and variable pitch drives are packed separately when ordered with Exhausters/Ventilators.
