40-micron sintered bronze replacement element for Arrow Pneumatics standard particulate / water-removing filters (F33x series). Swapping in a fresh element restores full depth filtration, protecting your tools, valves, and finished work from water, oil condensate, pipe scale, dirt, and rust — and keeping airflow and pressure drop where they should be. Details Type: Particulate filter element, 40 micron Material: Sintered bronze — high-strength, re-cleanable depth filtration Fits: Arrow Pneumatics F332 / F333 / F334 standard particulate filters Part number: EK33 Routine element replacement is the simplest way to keep a compressed air filter performing like new. Keep a spare EK33 on the shelf so a clogged element never means downtime. Note: This is an equivalent replacement part, not an original equipment manufacturer (OEM) part number. Some manufacturers require OEM parts to maintain warranty coverage.
