Air Oil Separators for Industrial Air Compressors

Find replacement air oil separators for industrial air compressors at Fab Heavy Parts. Our air oil separator collection includes separator elements, spin-on filters, and selected separator kits listed for equipment from Ingersoll Rand, Kaeser, Atlas Copco, Sullair, Gardner Denver, and other compressor manufacturers.

In oil-injected air compressor systems, an air oil separator helps remove entrained lubricating oil from compressed air before it leaves the separation system. Selecting the appropriate replacement is an important part of compressor maintenance, especially when your existing separator is due for service or its condition requires inspection.

Air Compressor Oil Separators by Brand and Model

This air oil separator collection covers multiple compressor applications, with replacement options identified by equipment models and part references.

  • Ingersoll Rand: Separator elements listed for LX15, LX22, LX30, SSRM22, SSRM30, and selected portable compressor models.

  • Kaeser: Replacement separators listed for M-series, SM-series, and other compressor applications, including references 6.3795.0 and 6.3793.0.

  • Atlas Copco: Air oil separator filters and elements identified by references such as 1092203407 and 1092203417.

  • Sullair: Separator kits listed under references 250034-124 and 250034-130 for selected TS32, LS25S, VS16, and VS20 compressors.

  • Gardner Denver: Replacement separator elements listed for selected compressor models, including products identified by reference 200ECM035.

Each application should be checked against the individual air oil separator listing. A separator intended for one compressor configuration is not automatically suitable for another model from the same manufacturer.

Separator Elements, Spin-On Filters, and Kits

Available replacement options include conventional separator elements, spin-on air oil separator filters, and application-specific kits. These product types can differ in their mounting arrangement, dimensions, sealing requirements, and included components.

For example, the collection includes a spin-on separator element identified by reference 24520728 for selected Ingersoll Rand LX-series compressors. Other products are listed as separator kits or individual filter elements.

Before choosing a replacement, identify the separator type used by your compressor and compare the part number of the existing separator with the product information.

Choosing the Correct Air Oil Separator

Start with your compressor manufacturer, model, and the part number of the existing separator. Check the equipment parts documentation to confirm the required replacement, especially if the compressor has undergone previous repairs or component changes.

Review the product description for application details and included components. Similar-looking separators may have different specifications and should not be selected by appearance alone.

If you are also servicing equipment intake filtration, explore our air filter collection for related filtration products. Air intake filters and air oil separators serve different functions and must be selected separately.

Frequently Asked Questions

How do I find the correct air oil separator for my compressor?

Start with your compressor's manufacturer, model, and the part number printed on the original separator. Compare these details with the air oil separator listing and your compressor's parts documentation. If your machine has multiple configurations, the serial number may also be needed to confirm the correct replacement.

Can I use an air oil separator with a different part number if it looks the same?

We do not recommend choosing a replacement based on appearance alone. Separators that look similar may differ in dimensions, sealing arrangements, or application requirements. Check the original part number and any documented replacement references before ordering. A matching appearance does not confirm interchangeability.

What is the difference between a spin-on air oil separator and a separator element?

A spin-on separator is designed for a compatible threaded mounting arrangement, while other separator elements are installed inside a designated compressor housing or separation vessel. The correct design depends on your compressor. Check the original component and equipment parts diagram before selecting a replacement.

Does an air oil separator kit include the gaskets and seals needed for installation?

Kit contents vary by product. Some air oil separators are for individual separator elements, while others are described as kits. Before ordering, review the product description and included components to determine whether the required gaskets or seals are supplied. Do not assume that every separator kit contains all installation accessories.

What should I check if my compressor is still carrying oil into the air system after replacing the separator?

Continued oil carryover can have causes beyond the separator element itself. The compressor's oil level, oil return system, operating conditions, and separator installation may require inspection. Confirm that the correct replacement was installed and follow the manufacturer's troubleshooting procedures. Compressor systems can contain pressurized air and hot oil, so servicing should only be performed after the equipment has been safely shut down and depressurized according to its service instructions.
