Typical Installation - Commercial Kitchen (Grease)

The USGF is specifically designed for heavy restaurant grease and food service applications. These fans are UL and cUL Listed for grease removal and have been tested under high temperature (400° F) and abnormal flare-up (600° F) conditions.

Due to high temperatures and grease-laden airstreams in commercial kitchen ventilation, system designers must be aware of governing codes and guidelines. The National Fire Protection Association (NFPA) is the primary source upon where many codes for commercial kitchens ventilation are based. Selected information from NFPA is shown below. Local code authorities should be consulted before proceeding with any kitchen ventilation project.

Exhaust fans used in kitchen ventilation applications must have external wiring. (Wiring must not be installed in airstream.)
