Greenheck Introduces Sidewall Reversible Fans
Greenheck's new Sidewall Propeller Reversible Fans offer reversible operation, giving users the flexibility of either exhausting or supplying clean air. Typical applications include factories and warehouses.
Model SBCR (belt drive) and SCR3 (direct drive) incorporate a cast aluminum propeller and a double spun venturi, which are designed to allow equal performance in either direction. These sidewall fans are also available with all of Greenheck's standard sidewall accessories, including wall housings, wall collars, dampers, damper guards, and weatherhoods.
