Size a Filtersoft Compressed Air Filter

To size a filter housing you need your operating pressure (PSI) and air flow (SCFM).

Find the pressure correction factor that corresponds to your operating pressure in the table 1.
Multiply the Corrected Factor from step 1 against the Nominal Flows in Table 2 until you find the housing that will handle your operating flow
Select the housing large enough to handle your operating flow (SCFM)

Sizing Example
Givens:
Operating Flow: 330 SCFM
Pressure: 160

[FFC32 Housing] 1.25 * 223 = 290 SCFM (Still not large enough.) [FFC33 Housing] 1.25 * 280 = 350 SCFM
Housing Selected: FFC33
