Use cases & applications
Heavy-Duty Continuous Operation
In manufacturing plants running multiple shifts, the separator handles high condensate loads without clogging, reducing unplanned downtime for maintenance.
Remote or Harsh Environments
For outdoor installations or dusty workshops, the durable construction withstands temperature fluctuations and particulate ingress, maintaining consistent air quality.
Fleet Maintenance Consolidation
Facilities with mixed compressor brands can standardise on one separator part number, simplifying inventory management and reducing stockholding costs.
Retrofit Upgrades
When upgrading older Atlas Copco GA series compressors (e.g., GA 90 VSD), this separator integrates seamlessly, improving moisture removal efficiency without system modifications.
Frequently asked questions
How can I confirm this separator fits my compressor?
Check your compressor model against the verified list: Atlas Copco GA 90 VSD, GA 75 from s/n 460001, and GA 55 from s/n 460001. For other brands, compare dimensions: 305 mm height, 239 mm outer diameter, 177 mm largest inner diameter, and 400 mm largest outer diameter.
What is the filtration rating of this separator?
This separator is a separator, not a filter. It removes bulk liquids and large particulates via centrifugal action. It does not have a micron rating; for fine filtration, use a downstream filter.
What are the thread and connection details?
We do not have verified thread specifications. The dimensions provided (outer diameter 239 mm, largest inner diameter 177 mm) are for the body. Ensure your housing accommodates these sizes.
Is this aftermarket separator as good as the branded version?
Our aftermarket separator is built to the original dimensions and ratings. It is a direct replacement for brands like Atlas Copco and Donaldson, offering equivalent performance at a lower cost.
How do I install this separator?
Installation is similar to the OEM part: turn off the compressor, depressurise the system, remove the old separator, and replace with the new one. Ensure O-rings are seated properly. No special tools required.
