Maintain cleaner compressed air and dependable compressor performance with the Ingersoll Rand Separator Replacement - 39863857, an air and oil separator element designed for compatible Ingersoll Rand rotary screw compressors. This separator removes entrained lubricant from the compressed air stream before the air continues downstream, helping reduce oil carryover while supporting proper oil recovery within the compressor system. Replacing a worn, saturated, or restricted separator can help control pressure drop, maintain efficient airflow, reduce lubricant consumption, and protect downstream compressed air equipment.

  • Reduces Oil Carryover: Separates lubricant mist from compressed air to help maintain cleaner discharge air and proper oil recovery.
  • Supports Compressor Efficiency: A clean separator helps control pressure differential and maintain dependable airflow through the compressor system.
  • OEM Compatible Replacement: Built as a replacement for Ingersoll Rand part number 39863857.

Frequently Asked Questions

Is the 39863857 separator compatible with my Ingersoll Rand compressor?

The 39863857 is an Ingersoll Rand air/oil separator element used in compatible rotary screw compressors. Ingersoll Rand uses different separators across horizontal, vertical, horsepower, and serial-number configurations. Always verify 39863857 in the compressor parts manual before ordering. Not sure? Reach out with your compressor model and serial number and we’ll help confirm compatibility.

What does the 39863857 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 39863857 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 Ingersoll Rand 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 Ingersoll Rand compressors?

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