VENT CAP SELECTION

1.To determine minimum free area required for vent, divide the required CFM flow by the maximum recommended free area velocity of 750 FPM. Given 125 CFM: Min. free area = 125 CFM/750 FPM = 0.16 sq. ft.

2. From the Dimension table, find the corresponding minimum vent size. Model SXL 10 has 0.19 sq. ft. free area.

3. Verify the static pressure drop through the vent from the Pressure Drop Chart. Velocity of 750 FPM has 0.09 in. w.g. static pressure drop.
