Van-Packer grease duct products offer unsurpassed versatility. We offer our Model GRZ grease duct in either square or rectangular configurations. The maximum allowable width to height ratio is 6 to 1, for instance 6" x 36". Our Model GZ round grease duct is offered in diameters from 6" to 36" I.D. with the ability to mix round or rectangular grease duct parts in a system. This allows the grease duct to be installed with minimal head room requirement while still taking advantage of the low pressure drop and high flow rates allowable with round grease duct.
