Standard unit has digital gauges and panel mounted variable speed controller. 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. A duct leakage tester consists of a calibrated fan for measuring an air flow rate and a pressure sensing device to measure the pressure created by the fan flow.
Featuring the latest us340x ductester, a dm32x touchscreen testing gauge, and our bestselling minipack to speed up equipment setup, this patented system can save you at least 30 minutes per house, on top of tape costs Designed for professionals, this duct leakage testing equipment is the perfect choice for those just starting out in the industry. Our duct air leakage tester (dalt 6900), delivers the most accurate test results in either positive or negative setting while delivering ±10 inches of water gauge pressure in the duct. Duct leakage testers are essential tools used to measure the amount of air escaping from hvac ducts, helping to identify inefficiencies, reduce energy consumption, and ensure compliance with building codes and industry standards.
