SMC AM-EL550, direct aftermarket replacement. Aftermarket replacement for the SMC AM-EL550 mist separator element. It fits SMC AM550C units (and the earlier AM550 without the C suffix) and is made to the same size, so it fits the bowl in place of the original.
The AM mist separator takes out oil mist and fine particles down to 0.3 µm. It is the usual stage after a main line filter and before a micro mist separator, and it protects valves and cylinders from compressor oil carry over. Sold as a single element, shipped worldwide, and covered by our
30 day money back guarantee and
price beat guarantee.

Use cases & applications
Oil mist removal
The AM catches the oil aerosol a compressor sends down the line, so valves, cylinders and tools stay clean.
Pre-filter for micro mist separators
Fitted ahead of an AMD 0.01 µm separator, it takes the bulk of the oil so the finer element lasts longer.
General plant air
Blow off, air tools and pneumatic machinery that do not need 0.01 µm air are well served by a 0.3 µm mist separator.
Planned maintenance
Change the element when the pressure drop reaches 0.1 MPa or every two years, whichever comes first.
Frequently asked questions
Is this a genuine SMC part?
No. It is an aftermarket element made to fit. It is not made by or affiliated with SMC; the SMC number AM-EL550 is shown only so you can match the part you are replacing.
How do I know it fits?
Check the model on the unit's body. This element fits SMC AM550C units (and the earlier AM550 without the C suffix). If the old element is marked AM-EL550, this is the replacement.
What else should I check at a change?
Check the bowl O-ring when you change the element and replace it if it is flattened or cracked, and make sure the auto drain is clear.
