Obround Grease Duct

“SlimVent™ is the industry’s only double wall UL 1978 and UL 2221 Classified grease duct product that is designed as a safer alternative to field fabricated non UL listed grease ducts. SlimVent™ is designed for low overhead clearances where no round grease duct will fit, requiring 28% less space. This product is zero-clearance to combustibles and two-hour fire-rated, eliminating the need for a fire-rated chase and secondary insulation. Installation is quick and simple with no field welding required. Schebler provides complete system design including access doors for system cleaning.
