Sullair Separator Replacement - 250034-124

Help maintain cleaner compressed air and dependable compressor performance with the Sullair Separator Replacement - 250034-124, an air/oil separator designed for compatible Sullair compressor systems. This separator helps remove oil aerosols from the compressed air stream so lubricant can remain in the compressor system while cleaner air continues downstream. Replacing a worn, saturated, or restricted separator during routine maintenance can help reduce oil carryover, limit lubricant loss, protect downstream equipment, and support efficient compressor operation.

  • Reduces Oil Carryover: Helps separate oil mist from compressed air to support cleaner discharge air and reduce contamination in the air stream.
  • Supports Downstream Equipment Protection: Helps limit oil exposure before compressed air reaches filters, dryers, tools, and other connected equipment.
  • Designed for Sullair Applications: Identified as part number 250034-124 and listed as an air/oil separator for compatible Sullair compressor systems.
  • OEM Compatible Replacement: Built as a replacement for Sullair part number 250034-124 to support routine separator maintenance and reliable compressor performance.

Keep compressed air cleaner and help reduce avoidable oil loss with the Sullair Separator Replacement - 250034-124, a practical replacement part for supporting long term Sullair compressor reliability.

Frequently Asked Questions

Is the 250034-124 separator compatible with my Sullair compressor?

The 250034-124 separator is designed for Sullair air compressors that require this exact air/oil separator part number. Compatibility should always be confirmed by matching 250034-124 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 250034-124 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 250034-124 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 Sullair 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 Sullair compressors?

Absolutely. We stock air filters, oil filters, separators, lubricants, and more for Sullair 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 Sullair 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 Sullair Compressor. It covers the recommended options for rotary screw compressors and helps you match your compressor with the proper oil.
