Dusty Industrial Environments
In workshops or factories with high airborne particulate levels, the 3 µm borosilicate micro glass fibre media ensures efficient separation of oil and water aerosols, protecting downstream equipment and maintaining air quality.
Continuous-Duty Compressor Operation
For compressors running extended shifts, this separator's robust construction and 3.3 kg weight handle consistent flow without degradation, reducing maintenance frequency and downtime.
Fleet Maintenance Consolidation
When servicing multiple compressor brands like Alup, Ceccato, and Chicago Pneumatic, this single separator part number simplifies inventory management, as it fits various models across different manufacturers.
High-Humidity Applications
In humid climates, the separator's Out-In flow design and fine filtration effectively remove condensed moisture, preventing corrosion and ensuring dry air output for pneumatic tools and processes.
Check your compressor's brand and model against the verified list in the description. If your machine is not listed, compare the dimensions: outer diameter 260 mm, hole diameter 13.5 mm, pitch circle diameter 215 mm, and body height 305 mm. Also ensure flow direction is Out-In.
The separator uses borosilicate micro glass fibre media with a filtration rating of 3 µm. This is suitable for general compressed air applications requiring removal of oil and water aerosols.
Key dimensions: outer diameter 260 mm, hole diameter 13.5 mm, pitch circle diameter 215 mm, body height 305 mm, and inner diameters of 108 mm and 110 mm. Measure your existing separator to verify compatibility.
This is an aftermarket replacement, not a genuine OEM part. It is built to the original dimensions and ratings and directly replaces separators from brands like Alup, Atlas Copco, Ceccato, and Chicago Pneumatic.
Installation is straightforward: remove the old separator, clean the mounting surface, and fit the new one with the flow direction arrow pointing outward (Out-In). Ensure the gasket is properly seated. Torque to manufacturer specifications if available.
We offer a 30-day money-back guarantee and a price-beat guarantee. Worldwide shipping with tracking is available. Contact us for specific delivery times to your location.
A flanged air oil separator element for Mark RM, RMB, MSC and CSC screw compressors that replaces Mark 6221374450: borosilicate micro glass fibre at 3 micron, out-in flow, 305 mm tall with a 260 mm flange on a 215 mm bolt circle. It also crosses to Mark 2200640584, Ceccato 2200640625, Atlas Copco 6221374400 and Sotras DC 3188, sold as SPM-SEP-1101.
When a separator on a Mark RM or CSC machine reaches the end of its life, the pressure drop across it climbs and oil starts reaching the air net. Replace it on the service interval or when the differential pressure warning comes up, with new gaskets and a clean flange face.
Same flange, bolt circle, body diameter and height as the elements it cross references. It is an aftermarket separator made in China, sold under SPM-SEP-1101, with Mark, Ceccato and filter brand numbers listed for matching.
Does it replace Mark 2200640584?
Yes. Mark 2200640584, 2200640625, 640584 and 6221374450 are all in the cross reference list.
Which Mark compressors is it listed for?
RM 37, RM 45, RMB 22, RMB 30, MSC 22 to MSC 55 and CSC 30 to CSC 75, including the inverter versions of the CSC 50 and CSC 60.
What is the filtration rating?
3 micron, borosilicate micro glass fibre media, with out-in flow.
