To correctly select a water separator model, the flow rate of the water separator must be adjusted for the minimum operating pressure of the system.

1. Obtain the minimum operating pressure and maximum compressed air flow rate at the inlet of the filter.

2. Select the correction factor for minimum operating pressure from the Correction Factors table below. Always round down, e.g. for 76.9 psi (5.3 bar), use 72.5 psi (5 bar) correction factor..

3. Calculate the minimum filtration capacity.
Minimum Filtration Capacity = Compressed Air Flow Rate x CFP

4. Using the minimum filtration capacity, select a water separator model from the Specifications table (water separator selected must have a flow rate equal to or greater than the minimum filtration capacity).
