International. Greenheck unveiled the redesign of the USF model single-width centrifugal utility sets in sizes 4 to 24 to incorporate more functions and options.
The USF now offers expanded direct drive selections with Vari-Green® engines up to 10 hp. Factory-mounted loose controls with VFDs are now available with direct or belt drive engine configurations up to 30 hp. Mounting options have been expanded to include curb cap, curb cap with inlet box, and equipment brackets up to 24 inches with spring isolators.
The USF can be selected with forward, backward or higher efficiency curved aerodynamic centrifugal wheels and many discharge arrangements that allow for different directions of airflow without system losses due to duct turns.
Greenheck's versatile USF model can be used in a wide selection of indoor or outdoor supply or exhaust applications, from light and medium-duty general ventilation business requirements to those requiring high airflows, such as manufacturing processes, emergency, continuous high temperature, or greased loaded exhaust.
The USF model is licensed to carry the AMCA seal for fan energy index (FEI) and air and sound performance.
