Ingersoll Rand 89295976 Air Filter Element

The 89295976 air filter element is a genuine Ingersoll Rand intake filter designed for 4–22 kW small rotary screw air compressors. Its high-efficiency synthetic fiber media blocks dust and airborne particles from entering the airend, protecting rotors, bearings and shaft seals from wear and extending compressor service life.

As an original intake filtration part, the 89295976 is built to Ingersoll Rand global technical standards and is a widely used service item for small screw compressor maintenance across the R, UP, V, EW and RM-C series. If you are unsure of fitment, provide the compressor serial number and we will confirm the correct part.

Installation and Maintenance

Replacement interval: Every 2,000–4,000 hours or 6–12 months (whichever comes first) under standard conditions; every 1,000–2,000 hours in high-dust environments such as construction sites, mines and woodworking shops. Replace immediately if the media is visibly darkened or heavily loaded, or if pressure drop reaches 600 Pa.

1. Shut down and isolate: Switch off compressor power and confirm the unit has fully stopped.
2. Open the filter housing: Release the retaining nut or clips and remove the cover.
3. Remove the old element: Pull out the old 89295976 element and check whether the center gasket remains in the housing groove.
4. Clean the housing: Wipe the inner walls and sealing face with a clean cloth. Do not reverse-blow a loaded element and reuse it.
5. Inspect the new element: Verify part number 89295976; check media, pleats, end caps and gasket for damage or aging.
6. Install the new element: Slide it onto the center stud and ensure the gasket seats evenly top and bottom without skewing.
7. Refit the cover: Reinstall the cover and tighten the nut or clips evenly for a gap-free seal.
8. Start-up check: Start the compressor and listen for air leaks at the intake; confirm normal operation.

FAQ

Q: Is the 89295976 a genuine Ingersoll Rand part?
A: Yes. It is an original Ingersoll Rand part produced to global technical standards and fits the original intake filter housing.

Q: Which compressors use this element?
A: It is a legacy common part covering R4i/R5.5i/R5.5ie/R5.5n/R7.5i/R7.5n/R11i/R11n, RM15i-C/RM22i-C, UP5 11/15/18/22, V15 Auto/V22 Auto, VSD15/VSD22 and EW5-22. Provide your serial number if you are unsure.

Q: Does the 89295976 replace the newer air filter part number?
A: The 89295976 is the legacy design. Some newer models use a different part number, and mounting dimensions or interfaces may differ. Do not interchange without confirming via serial number.

Q: How do I know when to replace the air filter?
A: Replace when the media is visibly darkened or heavily loaded, when operating pressure drop reaches the 500 Pa alarm value, or when the 2,000–4,000 hour / 6–12 month interval is reached.

Q: What happens if the air filter is left too dirty?
A: A clogged element restricts intake, reducing delivered air flow and raising specific power and energy consumption. In severe cases, dust enters the airend and wears rotors, bearings and seals, increasing oil carryover and potentially causing airend failure.
