Use cases & applications
High-Volume Compressed Air Systems
In facilities with continuous-duty compressors like the Atlas Copco GA 110 series, this separator handles flow rates up to 1860 m³/h, ensuring efficient removal of liquid aerosols and particulates without restricting air delivery.
Dusty or Humid Environments
The 3 µm borosilicate micro glass fibre media captures fine contaminants common in outdoor or poorly filtered intake air, protecting downstream equipment from moisture and debris.
Extended Maintenance Intervals
With a 5 bar collapse pressure, this element withstands pressure differentials that occur during long service periods, reducing the frequency of replacements in high-usage operations.
Inventory Consolidation for Multi-Brand Fleets
Cross-referencing with brands like Mann-Filter, Sotras, and HiFi Filter allows maintenance teams to stock a single separator that fits multiple compressor models, simplifying inventory management.
Frequently asked questions
Will this separator fit my Atlas Copco GA 110 compressor?
Yes, this separator is a direct replacement for the separator element in Atlas Copco GA 110 PLUS and GA 110 compressors (CE version from 04/2008). Always verify your compressor's serial number to confirm compatibility.
What is the filtration rating and media type?
The element uses borosilicate micro glass fibre media with a filtration rating of 3 µm, effectively capturing fine particles and liquid aerosols from the compressed air stream.
What are the dimensions and how does it fit?
The total height is 450 mm, outer diameter 399 mm, and inner diameter 315 mm. The largest outer diameter is 550 mm. It installs with an Out-In flow direction. Ensure your housing accommodates these dimensions.
Is this an OEM or aftermarket part?
This is an aftermarket replacement built to the original dimensions and ratings. It is not a genuine Atlas Copco part but offers equivalent performance at a lower cost.
How do I install the separator element?
Installation is similar to the original element: turn off the compressor, depressurize the system, remove the old separator, clean the housing, insert the new element with the correct flow direction (Out-In), and reassemble. Refer to your compressor manual for detailed steps.
