Higher pressure creates leaks that allow more accurate detection of small holes
B
25 Pascals matches the operating pressure of all residential HVAC systems
C
Using a standardized pressure enables comparison between different systems and provides a repeatable benchmark for testing and verification
D
25 Pascals is the maximum safe pressure for flexible duct systems
