Lube Retail First Floor Fan Model: Retrotec 2000 Fan SN: Fr4000823 Gauge Model: Gauge SN: 201621 DM-2 Leakage rate The measured air flow at a test pressure of 75 Pa was 1310 CFM which equates to an equivalent leakage area of 90.45 square inches which also equates to a one inch gap 7.5 feet long. Your building has a leakage rate that would be equivalent to a hole of this size if all the holes and cracks in the exterior were added together. - Results: Flow per unit envelope area at 51CFAI/ft l 0.24 +/ a.oro Since the standard is 0.25 CFM or less air leakage at 75 Pascals of pressure, this building PASSES this standard.
