CRC Filter Sizing Guide
Find the Exact Fit for Your Rig
Wrong filter sizing causes leaks, pressure spikes, and lost production time. While pre-packed AFS filter cups eliminate messy loose powder and channeling, you still need to ensure a perfect mechanical fit.
Use this quick 3-step guide to select the right cartridge for your closed-loop system.
Step 1: Pick Your Column Size (2.5" vs 4")
The primary measurement you need is the Spool Diameter of your extraction spool. AFS filter cups feature a molded outer rim that seats directly into standard sanitary columns.
