Grease Fan

Commercial cooking equipment that produces smoke- or grease-laden vapors must have sufficient mechanical and structural integrity, resiliency and stability. 

This includes hoods, ducts, fans/air movement, fire suppression systems, and special grease collection equipment. These components must operate properly, and be easily accessible for cleaning and inspections.

Only ENERVEX’s GSV Grease Fan is designed to support high exhaust temperatures at a high discharge velocity – reducing fire risk to operators, occupants and property while providing no-worries code compliance under NFPA 96 codes and standards. This easy-to-install grease fan provides adequate airflow in grease duct systems..
