Metal-Fab Inc. has introducted its new G Value factory-built grease-duct system. The company reports that the system was designed to reduce the cost of grease duct installations, while providing an enhanced level of protection where life and safety issues are important. It is approved by Underwriters Laboratories, and the manufacturer claims that this new kitchen ventilation duct has been exposed to more testing criteria and received more listings than any other type of grease duct system, factory-built or site-built welded and wrapped. The product comes with a limited lifetime warranty. The design features of G Value duct includes an integral chase, steel-encased insulation, round shape, consistent factory-built construction, stainless steel flue, and no-weld V-band joint assembly. The models are available in diameters of 6 inches to 48 inches.
