Joy 543117-9 Air/Oil Separator Replacement
The Joy 543117-9 air/oil separator replacement is designed for use in compatible Joy rotary screw air compressors.
This aftermarket separator removes fine oil aerosols from the compressed air stream before the air exits the separator vessel. Its high-efficiency media helps reduce oil carryover while supporting reliable compressor performance and proper lubricant recovery.
The 543117-9 replacement features outside-to-inside airflow and a nominal filtration rating of 0.3 micron. With a 20.66-inch body height and a 13.25-inch flange diameter, it is manufactured to match the fit and operating requirements of the original separator.

Replacement Air/Oil Separator
Air/oil separators are essential to maintaining efficient compressor operation. A worn or saturated separator can increase oil carryover, create excessive pressure drop, increase energy consumption, and place additional strain on the compressor system.
Replacing the separator at the recommended service interval helps maintain compressed-air quality, minimize lubricant loss, and protect downstream equipment. Inspect the separator regularly and replace it whenever pressure differential or oil carryover exceeds the compressor manufacturer’s recommended limits.
This is an aftermarket replacement air/oil separator manufactured to meet or exceed the fit, form, and performance requirements of Joy 543117-9.
