Flow Rates Stated flows are for operation at 7 bar (g) (102 psi g) with reference to 20°C, 1 bar (a), 0% relative water vapour pressure.

Select a correction factor from the CFIT table for the relevant compressor type, remembering to always round up e.g. for 37°C use the 40°C correction factor. • For pressure dewpoint, select a correction factor from the CFID table. • For oil vapour concentration, select a correction factor from the CFIV table, remembering to always round up e.g. for 3.25g/m3 use the correction factor for 4mg/m3.
