Continuous-Duty Industrial Compressors
In manufacturing facilities where compressors run 24/7, the SPM-SEP-1120 ensures efficient oil separation, reducing carryover and maintaining air quality. This helps prevent downstream equipment fouling and extends the life of your compressed air system.
Harsh Environment Operations
For compressors operating in dusty or humid conditions, this separator's robust construction provides consistent filtration performance. It helps protect sensitive pneumatic tools and machinery from contamination, minimising unplanned downtime.
Fleet Maintenance and Inventory Consolidation
If you maintain multiple Atlas Copco compressors (GA 11 to GA 22), using a single aftermarket separator part number simplifies stock management. The SPM-SEP-1120 fits all these models, reducing the number of different filters you need to hold.
Cost-Effective Replacement Schedules
For facilities that replace separators on a fixed schedule, this aftermarket option offers a budget-friendly alternative without compromising fit. It allows you to maintain OEM-equivalent performance while lowering replacement costs over time.
Check your compressor's serial number against the verified list: for Atlas Copco GA 11, GA 15, GA 18, and GA 22, this filter fits units from s/n 217792 or s/n 246349 depending on the model. For other brands like Adicomp, we recommend verifying dimensions (body height 174 mm, outer diameter 134 mm, largest outer diameter 238 mm) against your current part.
The SPM-SEP-1120 is an aftermarket separator designed for oil separation in compressed air systems. Specific micron rating or media details are not provided in the verified specifications. It is built to match OEM specifications for the listed cross-references.
The body height is 174 mm, total height is also 174 mm, largest inner diameter is 75 mm, outer diameter is 134 mm, and largest outer diameter is 238 mm. These dimensions ensure it fits the filter housing of compatible compressors. Always compare with your old filter before installation.
No, this is an aftermarket separator. It is a direct replacement for the original parts from brands like Atlas Copco, Donaldson, and others listed. It is built to match OEM specifications but is not manufactured by the original equipment manufacturer.
Installation is similar to the original part. Ensure the compressor is off and depressurised. Remove the old separator, clean the housing, and install the new one. Tighten according to manufacturer guidelines. Refer to your compressor's manual for specific steps.
