Hooded Roof Propeller Fans - Greenheck-USA

Reversible Fans Ventilation requirements are often subject to daily or seasonal changes in temperature. Greenheck’s reversible fans (models RPDR, RPBR, RPDRF, and RPBRF) are designed for non-ducted systems or those with short duct runs and offers the ability to either exhaust or supply air on demand to maintain comfortable working conditions.
