For sale is a new Air Duct Sizing Calculator. This is a slide chart type tool used to size round or rectangular ductwork using the Velocity Method or the Friction Loss Method. This tool is easy to use with instruction printed on the front. The back is loaded with useful information such as approximate friction equivalents, and much more. This item is made of thick durable cardboard stock with metal corner rivets and measures 6.5 inches long by 3.5 inches wide. I also have a Trane Ductulator style chart in my ebay store and R-22 and R-410a superheat/subcooling charts. Check them out while supplies last! Follow the link below to my ebay store!! |
