It’s designed to be simple to use, accurate, and extremely convenient Measure duct leakage in commercial systems up to 295 cfm at 8 inches water column (in wc) with the first truly lightweight (21 lb) handheld commercial ductester It also includes the newly released, industry changing dm32x gauge With 1700 watts of power available, any comparable commercial duct tester will weigh 120 lb or more. Eurovent 2/2, leakage rate in sheet metal air distribution systems Smacna air duct leakage test manual.
It can generate up to 150l/s of airflow and test up to 2500pa static pressure. For duct leakage testing, the standard pressure used is 25 pascals, which is close to the operating pressure of a typical duct system This means that when we measure, say, 120 cubic feet per minute of duct leakage at 25 pascals (written 120 cfm25), that number is a pretty good estimate of how much air leaks out of the duct system while it’s.
