A 6-inch duct is good for about 150 cfm, slightly more with a fan. Ducts are open holes for fire and smoke to pass through, so metal lining is there for safety and a hard surface to make it possible to clean. Giving that up has been done to get return air done. www.heatpro.us energy businessmen's knowledge Yes, you really have to find out the MAKE and MODEL to get good answers.
