Frequently Asked Questions

What is the Sullair 02250212-657 conversion kit replacement?

The 02250212-657 pre-2019 conversion kit replacement is used to update compatible Sullair portable compressors that originally used the older 02250212-657 30-micron fuel/water separator element.

The original 02250212-657 element has been superseded on these older machines by a newer fuel/water separator assembly.

For compressors built prior to July 2019, the update requires a conversion kit, rather than simply installing the later replacement element.

Compatibility should always be confirmed by checking your manual and verifying the model and serial number before ordering. Not sure? Reach out with your compressor model and serial number and we’ll help confirm compatibility. 

Why does my pre-2019 compressor need a conversion kit?

The original fuel/water separator assembly used with 02250212-657 was superseded.

On applicable compressors built before the production change, the newer replacement element does not simply install into the original housing.

The conversion kit updates the machine to the newer fuel/water separator configuration so future filter replacement can use the current element.

What does the original 02250212-657 filter do?

The 02250212-657 is a 30-micron engine fuel/water separator element.

Its job is to remove:

  • Water
  • Dirt
  • Rust
  • Sediment
  • Other fuel contamination

before diesel fuel reaches sensitive engine components.

What are the signs that the fuel/water separator needs service?

Common signs include:

  • Water visible in the separator bowl
  • Restricted fuel flow
  • Engine hesitation
  • Hard starting
  • Loss of engine power
  • Irregular engine speed under load
  • Dirty or contaminated fuel
  • Scheduled maintenance interval reached

Do not wait for engine performance problems if the filter is already due for service.

Is this an OEM part?

This is an OEM-equivalent replacement conversion kit designed to meet the same performance standards as the original Sullair kit.  

How difficult is it to install?

Installation is generally a moderate diesel fuel-system maintenance task. It is more involved than replacing a normal spin-on fuel filter because the original assembly is being updated. Technicians should follow the exact Sullair and engine service instructions for the compressor.

Do you carry other parts for Sullair?

Absolutely. We stock a range of air filters, oil filters, separators, synthetic oils, and many other maintenance parts for Sullair equipment. If you don’t see what you need, just ask and we’ll help you find it.

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.
