Frequently Asked Questions

Is the 250034-085 separator compatible with my compressor?

The 250034-085 air-oil separator replacement is a direct replacement for Sullair compressors that originally use this separator element. It’s engineered to fit the OEM separator housing and media requirements. Not sure? Check your compressor’s parts manual or reach out and we’ll help confirm compatibility.

How often should I replace the 250034-085 separator?

Separators should be replaced at regular service intervals, typically every 4,000 hours of operation depending on your machine’s duty cycle and environment. Over time the separator media becomes saturated with oil and contaminants, reducing its efficiency. Regular replacement keeps the compressor running efficiently and protects downstream equipment.   

Why is it important to replace my separator regularly?

Separators remove oil from the compressed air before it exits the compressor. A clean separator reduces oil carryover into your air system, protects pneumatic tools and air-using equipment, improves air quality, and helps maintain efficient compressor operation. When a separator clogs or degrades, you’ll see increased oil in the air lines, which leads to wear and maintenance issues. 

Will this separator affect my compressor’s performance?

Yes, in a beneficial way. A fresh separator improves oil removal efficiency within the compressor, helping reduce internal temperatures, decrease pressure drop, and maintain cleaner air output. This, in turn, supports smoother operation and longer component life across the system. 

How difficult is it to install?

Installation is generally straightforward for most compressors. This separator is designed to fit into the existing separator housing just like the original. Most technicians can complete the swap with common tools during your scheduled maintenance. Always shut down and depressurize the compressor before servicing.

Do you carry other parts for Sullair compressors?

Absolutely. Alongside separators like the 250034-085, we stock air filters, oil filters, valves, synthetic oils, and many other maintenance parts to help you keep your Sullair compressor running reliably. If you don’t see what you need, just ask.

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.
