24 www.parker.com/gsfe Compressed Air Filters Flow Rates To correctly select a filter model, the flow rate of the filter must be adjusted for the minimum operating (inlet) pressure at the point of installation. 1. Obtain the minimum operating (inlet) pressure and maximum compressed air flow rate at the inlet of the filter. 2. Select the correction factor for minimum inlet pressure from the CFMIP table (always round down e.g. for 5.3 bar, use 5 bar correction factor) 3. Calculate the minimum filtration capacity. Minimum Filtration Capacity = Compressed Air Flow Rate x CFMIP 4. Using the minimum filtration capacity, select a filter model from the flow rate tables above (filter selected must have a flow rate equal to or greater than the minimum filtration capacity).

For flows at other pressures, apply the correction factors shown below. Product Selection & Correction Factors Filter Coding Example When ordering a filter for pressures above 16 bar g (232 psi g), use a manual drain. Replace F with M in product code. e.g. AC015BGFX becomes AC015BGMX.
