Ingersoll Rand 89295976 Air Filter Element
89295976 is a genuine Ingersoll Rand air intake filter element for small rotary screw air compressors in the 4–22 kW range. It uses high-efficiency synthetic fiber media to block dust, dirt, and airborne particles from entering the screw airend, protecting rotors, bearings, and shaft seals from wear and extending compressor service life.
Produced to Ingersoll Rand global technical standards, this element is a legacy common part covering R, RM-C, UP, V, VSD, and EW series machines. It is one of the most frequently replaced intake filters in small Ingersoll Rand compressor maintenance programs.

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 visual inspection shows darkening, heavy dust buildup, or differential pressure reaches 600 Pa
Installation Steps
- Shut down and isolate power: Turn off the compressor and confirm the unit has fully stopped.
- Open the filter housing cover: Loosen the retaining nut or clips and remove the cover.
- Remove the old element: Pull out the old 89295976 element and check whether the center gasket remains in the housing groove.
- Clean the housing: Wipe the inner walls and sealing surfaces with a clean cloth. Do not reverse-blow a loaded element with compressed air and reuse it.
- Inspect the new element: Confirm part number 89295976; check media for damage, pleats for deformation, end caps for cracks, and gasket for aging.
- Install the new element: Slide the new element onto the center stud, ensuring the gasket seats correctly top and bottom without skewing.
- Refit the cover: Reinstall the cover and tighten the nut or clips evenly to ensure a gap-free seal.
- Start-up check: Start the compressor, listen for air leaks at the intake, and confirm normal operation.
FAQ
Q1: Is 89295976 a genuine Ingersoll Rand part?
A: Yes. 89295976 is a genuine Ingersoll Rand spare part manufactured to Ingersoll Rand global technical standards and fits the original intake filter housing.
Q2: Which compressor models use 89295976?
A: This legacy common part covers a wide range: 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 rotary screw compressors. If you are unsure about your model, provide the serial number and we will confirm fitment.
Q3: How does 89295976 differ from newer air filter elements? Can they be interchanged?
A: 89295976 is the legacy design (marked "old version" in DMS notes). Some newer models may use a different part number. Mounting dimensions and interfaces may differ, so they are not freely interchangeable. Provide the serial number to confirm the correct replacement.
Q4: How do I know when to replace the air filter element?
A: Replace when: (1) visual inspection shows darkening or heavy dust; (2) operating differential pressure reaches the 500 Pa alarm value; or (3) the 2,000–4,000 hour or 6–12 month interval is reached.
Q5: What happens if the air filter element is too dirty?
A: A clogged element restricts intake air, reducing discharge volume and raising specific power and energy consumption. In severe cases, dust enters the airend, causing rotor and bearing wear, seal aging, higher oil carryover, and potentially airend failure.
