Frequently Asked Questions

Is the 157-170-S separator compatible with my Rotair compressor?

The Rotair Separator Replacement - 157-170-S is an air/oil separator filter used on compatible Rotair oil-injected rotary screw air compressors.

Always verify 157-170-S in your parts manual before ordering. Not sure? Reach out with your compressor model and serial number and we’ll help confirm compatibility.

What does the 157-170-S 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 157-170-S 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 Rotair 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.
