Use cases & applications
Continuous-Duty Industrial Sites
In factories running multiple shifts, this separator handles prolonged operation without frequent replacement. Its robust construction minimises downtime, keeping production lines moving.
Remote Construction Projects
On remote job sites where equipment reliability is critical, this separator ensures Atlas Copco compressors like the XAMS 1150 CD7 maintain consistent air quality. Its durable build reduces the need for emergency servicing.
Fleet Maintenance Consolidation
For operators managing a mixed fleet of Atlas Copco compressors, stocking one separator that fits models from the XAVS 900 CD7 to the XAH 2250 CD6 simplifies inventory and reduces storage costs.
High-Dust Environments
In dusty conditions such as quarries or demolition sites, the separator's effective filtration protects downstream components. It extends the life of valves and dryers by trapping particulates before they cause wear.
Frequently asked questions
How do I confirm this separator fits my specific compressor?
Check your compressor model against the verified list of Atlas Copco models above. If your model is listed, this separator is a direct fit. For unlisted models, compare the dimensions: total height 376 mm, outer diameter 255-262 mm, and inner diameters of 76 mm and 44 mm.
What is the filtration rating of this separator?
This separator is a coalescing separator designed to remove oil and condensate from compressed air. Its media provides efficient separation down to micron levels typical for industrial rotary screw compressors, though specific micron rating is not provided.
What are the thread sizes and how do I ensure correct fitment?
The separator has two inner diameters: a largest of 76 mm and a smallest of 44 mm. These correspond to the mounting threads or ports. Verify your compressor's thread sizes match these dimensions for a proper seal.
Is this an OEM or genuine Atlas Copco part?
No, this is an aftermarket replacement built to the original dimensions and ratings. It is not branded as genuine Atlas Copco but serves as a direct replacement for the original separator in the listed models.
How often should I replace this separator?
Replacement intervals depend on operating hours and conditions. Typically, separators are changed during scheduled compressor maintenance, often every 1,000 to 2,000 hours. Check your compressor manual for specific recommendations.
