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 for Alup Largo and Allegro 30 and 36 compressors built from November 2015, replacing Alup 6221374450. It uses borosilicate micro glass fibre rated at 3 µm with Out-In flow, a 260 mm flange on a 215 mm pitch circle and a 305 mm height. Sold as SPM-SEP-1101.
When the separator loads, the pressure drop across it rises and oil carry over into the air lines increases, so you see oil at the drains and higher running cost. Replace it on the service interval or when the separator pressure drop reaches the limit in your manual. Fit new gaskets and tighten the cover bolts evenly.
Same 3 µm glass fibre media, flange size and height as the Alup, Atlas Copco 6221374400, Ceccato 2200640584 and Oxfil SP.3188 numbers it cross references. It is an aftermarket separator made in China.
Does it replace Alup 6221374450?
Yes. 6221374450 is in the cross reference list, along with Atlas Copco 6221374400 and Chicago Pneumatic 2902021980.
Which Alup models is it for?
LARGO 30, LARGO 36, ALLEGRO 30 and ALLEGRO 36 built from November 2015.
What is the filtration rating?
3 µm, using borosilicate micro glass fibre media with Out-In flow.
What are the flange dimensions?
260 mm outside diameter, 215 mm pitch circle diameter and 13.5 mm hole diameter.
