Build a FilterFab C-Series Part Number
To choose the correct FilterFab model for your application, start by building a part number. You will need to know line size and pressure rating. See this example:
-
C-Series Filter Flowrate Information
Now check the model number you have determined above against the flowchart below to make sure that your choice will handle the flowrate of your application.
These flowrates are based on 1-1/2 psi pressure drop up to 150 psi; 3 psi for higher line pressures.

Now, using the C-Series Part Number you built above, you can download below the PDF of each model to see dimensions of the housing, filter element used, material specifications, and note what type of top closure and lifting mechanism is standard. You may also download a DWG drawing of the filter into your AutoCAD program. To download a PDF or DWG file simply right-click on the appropriate link and select “Save Target As …”
