The durable, corrosion-resistant engineered thermoplastic fan housing makes RB fans ideal for duct boosting and bathroom, living area and garage ventilation. These remotely mounted fans, unlike ceiling or wall-mounted fans, can silently draw from multiple intake points, such as over a bathroom tub, sink and toilet.
