Description

Atlas Copco Separator Replacement - 2901205500

Help maintain cleaner compressed air and reliable rotary screw compressor performance with the Atlas Copco Separator Replacement - 2901205500, a separator kit designed for compatible Atlas Copco oil injected screw compressor systems. This separator helps remove oil mist from the compressed air stream so lubricant can be collected and returned to the compressor while cleaner air continues downstream. Replacing a worn, saturated, or restricted separator during routine maintenance can help reduce oil carryover, support improved air quality, limit lubricant loss, and keep the compressor operating smoothly.

  • Reduces Oil Carryover: Helps separate oil mist from compressed air to support cleaner discharge air and reduce lubricant contamination downstream.
  • Supports Rotary Screw Compressor Performance: A properly functioning separator helps maintain airflow, reduce pressure drop, and support smooth compressor operation.
  • GA 30-40kW Separator Kit: Identified as Atlas Copco part number 2901205500 and listed as a separator kit for compatible GA 30-40kW oil injected screw compressor applications.
  • OEM Compatible Replacement: Built as a replacement for Atlas Copco part number 2901205500 to support routine separator maintenance and reliable compressor performance.

Keep compressed air cleaner and help reduce avoidable oil loss with the Atlas Copco Separator Replacement - 2901205500, a practical replacement kit for supporting long term Atlas Copco rotary screw compressor reliability.

Frequently Asked Questions

Is the 2901205500 separator compatible with my Atlas Copco compressor?

The 2901205500 separator is designed for Atlas Copco oil-injected screw compressors that require this exact separator kit part number. This part is commonly associated with Atlas Copco GA 30 to 40 kW compressor applications. Compatibility should always be confirmed by matching 2901205500 in your parts manual or by verifying your compressor model and serial number before ordering. Not sure? Reach out with your compressor model and serial number and we’ll help confirm compatibility.

What does the 2901205500 separator do?

Air/oil separators are responsible for removing oil aerosols and oil carryover from compressed air before that air leaves the compressor package. This allows oil to return to the sump while helping deliver cleaner compressed air downstream. 

How often should the 2901205500 separator be replaced?

Air/oil separators are commonly replaced about every 4,000 hours, depending on operating conditions and maintenance practices. They should be inspected regularly and replaced if signs of restriction, declining efficiency, or increased oil carryover are present.

Is this an OEM part?

This is an OEM-equivalent replacement separator designed to meet or exceed the fit and performance standards of the original Atlas Copco component while offering a cost-effective alternative.

Why is it important to replace my separator regularly?

A worn or overloaded separator can allow more oil carryover into the compressed air stream and may also contribute to reduced system efficiency. Replacing the separator on schedule helps support cleaner compressed air, proper oil separation, and more reliable compressor performance.  

How difficult is it to install?

Separator replacement is generally a routine maintenance task, though the process depends on the compressor’s separator housing design. Because this component is part of the pressurized air/oil system, the compressor should always be shut down, isolated, and fully depressurized before service is performed.

Do you carry other parts for Atlas Copco compressors?

Absolutely. We stock air filters, oil filters, separators, lubricants, and more for Atlas Copco compressors. If you don’t see what you need, just ask. We’re happy to help.

How do I know which oil to use in my Atlas Copco compressor?

Stationary rotary screw compressors may have specific oil requirements that differ from reciprocating or portable units. To make sure you’re using the right lubricant for your machine, check out our full guide here: Choosing the Right Oil for your Atlas Copco Compressor. It covers the recommended options for rotary screw compressors and helps you match your compressor with the proper oil.
