Description

Sullair Separator Replacement - 250034-087

Maintain clean compressed air and efficient compressor operation with the Sullair Separator Replacement - 250034-087. This air oil separator element is designed for Sullair rotary screw air compressors and removes lubricating oil from compressed air inside the separator vessel. By capturing fine oil mist and returning it to the compressor lubrication circuit, the separator helps reduce oil carryover, maintain air quality, and support reliable compressor performance.

  • High Efficiency Oil Separation – Advanced separator media captures fine oil aerosols from compressed air to help maintain clean air output.
  • Reduced Oil Carryover – Helps return lubricant to the compressor sump while keeping residual oil in compressed air extremely low.
  • Supports Compressor Efficiency – Proper separation helps maintain system pressure balance and protects downstream air equipment.
  • OEM Compatible Fitment – Designed to meet the dimensional and filtration specifications required for Sullair rotary screw compressor separator vessels.

Protect compressor efficiency and maintain consistent compressed air quality with the Sullair Separator Replacement - 250034-087, a critical filtration component designed to reduce oil carryover and support long term compressor reliability.

Frequently Asked Questions

Is the 250034-087 separator compatible with my Sullair compressor?

The 250034-087 air-oil separator is designed for Sullair rotary screw compressors that specify this exact part number in the service manual. If your compressor’s parts list includes 250034-087, this replacement separator is the correct fit. Not sure? Reach out with your compressor model and serial number and we’ll help confirm compatibility. 

What does the 250034-087 separator do?

This air-oil separator removes lubricating oil from the compressed air stream before the air exits the compressor. The captured oil is returned to the compressor’s lubrication system while clean compressed air continues through the system. 

How often should I replace the 250034-087 separator?

Air-oil separators in rotary screw compressors are commonly replaced about every 4,000 hours, depending on operating conditions and maintenance practices. Regular replacement helps maintain proper oil separation efficiency and airflow. 

Is this an OEM part?

This is an OEM-equivalent replacement separator. It’s manufactured to meet or exceed the dimensional and filtration performance standards of the original Sullair separator without the name-brand price tag. 

Why is it important to replace my separator regularly?

The separator removes oil from the compressed air stream before the air leaves the compressor. Over time the element becomes saturated with oil and contaminants, which can increase pressure drop, reduce efficiency, and allow excess oil carryover into the air system. 

How difficult is it to install?

Installation is typically straightforward for trained technicians. The separator element installs in the compressor’s separator tank or housing and replaces the existing 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.
