Frequently Asked Questions

Is the 2901145300 minimum pressure check valve kit compatible with my Atlas Copco compressor?

The 2901145300 is an Atlas Copco minimum pressure valve kit for compatible oil-injected screw compressor applications. Atlas Copco identifies 2901145300 as a kit valve minimum pressure for oil-injected screw compressor. Compatibility should always be confirmed by matching 2901145300 in your compressor manual and verifying the model, serial number, valve assembly, pressure range, and separator system configuration before ordering. Not sure? Reach out with your compressor model and serial number and we’ll help confirm compatibility. 

What does the 2901145300 minimum pressure check valve kit do?

The 2901145300 helps maintain minimum internal pressure in the compressor package and helps prevent reverse flow through the discharge system. In a compatible oil-injected screw compressor, it helps:

  • Maintain minimum separator or sump pressure
  • Support proper oil circulation
  • Support proper air and oil separation
  • Help prevent compressed air from flowing backward into the compressor package
  • Stabilize compressor operation during startup, loading, and unloading

What are the signs that the 2901145300 kit is needed?

Common symptoms can include:

  • Compressor failing to build or maintain minimum internal pressure
  • Air leaking backward after shutdown
  • Unstable loading or unloading
  • Oil carryover into the compressed air system
  • Separator pressure behaving abnormally
  • Excessive pressure drop through the discharge system
  • Valve sticking, contamination, or damaged seals found during service
  • Pressure-related fault codes or shutdowns

These symptoms can also be caused by leaks, separator issues, control-valve problems, sensors, or other pressure-control components. Inspect the full system first to identify the cause of the issue.

Is this an OEM part?

This is an OEM-equivalent replacement minimum pressure check valve kit designed to meet the same performance standards as the original Atlas Copco kit.  

How difficult is it to install?

Installing the 2901145300 is generally a moderate to advanced maintenance task because it involves the compressor’s pressurized air and oil separation system.

Before service, the compressor should be:

  • Fully shut down
  • Electrically locked out
  • Completely depressurized
  • Cooled to a safe working temperature
  • Positioned to contain any lubricant released during service
  • Verified so no stored pressure remains in the separator system

Installation typically involves accessing the minimum pressure valve location, documenting the original valve orientation, removing the worn valve components, inspecting the valve housing and sealing surfaces, installing the replacement 2901145300, and checking for leaks, pressure stability, and proper operation after startup.

Do you carry other parts for Atlas Copco?

Absolutely. We stock a range of air filters, oil filters, valves, synthetic oils, and many other maintenance parts for Atlas Copco equipment. If you don’t see what you need, just ask and we’ll help you find it. 

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.
