WebMcGill offers venturi tubes linked with airflow meters for four different leakage measurement ranges. Using a venturi tube and a digital flow meter with a variable speed blower, McGill AirFlow's Leak Detective Test Station can be quickly set up to measure leakage rates in duct systems with desired static pressures as high as 10 inches wg. WebSep 16, 2024 · A leak test carried out on a 1,000 m3 cleanroom using the Blower-Door-Test showed a leakage air rate n50 of maximum 0.5 at a pressure of +50 Pa. Consequentially, the exfiltration air volume (EXF) from the room is calculated as follows: 1000 m 3 x 0.5 m 3 .h -1 .m -3 = 500 m 3 .h -1
