Ingersoll Rand 89295976 Air Filter Element
The 89295976 air filter element is a genuine Ingersoll Rand inlet filter for 4–22 kW small screw air compressors. Its high-efficiency synthetic fiber media blocks dust and particulate from entering the airend, protecting rotors, bearings and shaft seals while supporting stable compressor performance.
As an original inlet filtration component, the 89295976 is built to Ingersoll Rand global technical standards and is a long-standing common part across R, UP, V, VSD, RM-C and EW series machines. It is one of the most frequently replaced inlet filters in small screw compressor maintenance.

Standards Referenced
- ISO 5011 — inlet air filter performance testing (efficiency and dust capacity)
- ISO 16889 — determination of beta ratio for hydraulic filters
- ISO 16890 / EN 779 — general ventilation air filter classification
- GB/T 14295 — air filters
- GB/T 6165 — air filter performance test methods (efficiency and resistance)
Maintenance and Installation
Replacement interval
- Standard conditions: every 2,000–4,000 hours or 6–12 months, whichever comes first
- High-dust conditions (construction sites, mines, woodworking shops): every 1,000–2,000 hours
- Replace immediately if the media is visibly blackened or heavily loaded, or if differential pressure reaches 600 Pa
Installation steps
- Shut down and isolate — switch off compressor power and confirm the unit has fully stopped.
- Open the filter housing — release the retaining nut or clips and remove the cover.
- Remove the old element — pull out the used 89295976 element and check whether the center gasket remains in the housing groove.
- Clean the housing — wipe the inner wall and sealing face with a clean cloth. Do not reverse-blow a loaded element with compressed air and reuse it.
- Inspect the new element — verify part number 89295976; check media for damage, pleat deformation, cracked end caps and aged gaskets.
- Install — slide the new element onto the center stud and ensure the gasket seats evenly top and bottom without skewing.
- Refit the cover — reinstall the cover and tighten nuts or clips evenly for a gap-free seal.
- Start-up check — start the compressor and listen for air leakage at the inlet; confirm normal operation.
Frequently Asked Questions
Q1: Is 89295976 a genuine Ingersoll Rand part?
A: Yes. 89295976 is a genuine Ingersoll Rand spare part produced to Ingersoll Rand global technical standards and fits the original inlet filter housing.
Q2: Which compressor models does 89295976 fit?
A: This is a legacy common part with wide coverage, including 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 small screw compressors. If you are unsure, provide the machine serial number and we will match it precisely.
Q3: How is 89295976 different from newer air filter elements? Can they be interchanged?
A: 89295976 is a legacy design, and some newer models may use a different part number. Mounting dimensions and interfaces can differ, so they should not be swapped without confirmation. Provide the machine serial number to check the correct replacement.
Q4: How do I know when to replace the element?
A: Replace when (1) the media is visibly blackened or heavily loaded, (2) differential pressure reaches the 500 Pa alarm value, or (3) the 2,000–4,000 hour / 6–12 month interval is reached.
Q5: What happens if the air filter is left clogged?
A: A clogged inlet filter restricts air intake, reduces discharge volume, raises specific power and energy consumption, and in severe cases allows dust into the airend, causing rotor and bearing wear, seal aging, higher oil carryover and possible airend failure.
