Frequently Asked Questions

Is the 250042-862 separator compatible with my Sullair compressor?

TThe 250042-862 separator is designed for Sullair rotary screw compressors that require this exact part number. Compatibility should always be confirmed by matching the part number in your compressor’s parts manual or by verifying your 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 250042-862 separator do?

The 250042-862 is an air/oil separator element. Its job is to help remove oil mist and oil carryover from compressed air before that air leaves the compressor package. This helps return oil back into the lubrication system while supporting cleaner compressed air output. 

How often should the 250042-862 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?

Installation is typically straightforward for a trained technician. The separator installs inside the separator vessel or housing as a direct replacement element. Always shut down and depressurize the compressor before performing maintenance.

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.
