Ingersoll Rand 89295976 Air Filter Element
Product Overview
The 89295976 air filter element is a genuine Ingersoll Rand intake filter designed for 4–22 kW small rotary screw air compressors. Using high-efficiency synthetic fiber media, it blocks dust, dirt and particulate matter from entering the screw airend, protecting rotors, bearings and shaft seals from premature wear and extending compressor service life.
As an original Ingersoll Rand intake filtration component, the 89295976 is manufactured to Ingersoll Rand global technical standards. It delivers low initial pressure drop, straightforward installation and stable filtration efficiency. This element is a legacy common part covering R series, UP series, V series, EW series and RM-C series small rotary screw compressors — one of the most frequently replaced intake filters in small Ingersoll Rand machines.

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 darkened media, heavy dust accumulation, or differential pressure reaches 600 Pa
Installation Steps
- Shut down and disconnect power: Turn off the compressor and confirm the unit has fully stopped.
- Open the air 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 seal remains in the housing groove.
- Clean the housing: Wipe the inner walls and sealing surface with a clean cloth. Never reverse-blow a loaded filter with compressed air for reuse.
- Inspect the new element: Verify part number 89295976; check media for damage, pleat deformation, cracked end caps or aged seals.
- Install the new element: Slide it onto the center stud, ensuring the seal seats correctly top and bottom without misalignment.
- 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 and listen for air leaks at the intake; confirm normal operation.
FAQ
Q1: Is the 89295976 a genuine Ingersoll Rand part?
A: Yes, the 89295976 is a genuine Ingersoll Rand spare part manufactured to Ingersoll Rand global technical standards, designed to fit original Ingersoll Rand intake filter housings.
Q2: Which compressor models use the 89295976?
A: This is a legacy common part with broad compatibility, 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 rotary screw compressors. If you are unsure about your model, provide the compressor serial number and we will match it precisely.
Q3: How does the 89295976 differ from newer air filter elements? Are they interchangeable?
A: The 89295976 is a legacy design (noted as "old version" in DMS). Some newer models may use a different part number. Installation dimensions and interfaces may differ, so they are not freely interchangeable. To confirm a replacement, please provide the compressor serial number.
Q4: How do I know when to replace the air filter element?
A: Replace in three cases: (1) visual inspection shows darkened media or heavy dust; (2) operating differential pressure reaches the 500 Pa alarm value; (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 causes insufficient intake, reduced discharge volume, higher specific power and increased energy consumption. In severe cases, dust enters the airend, wearing rotors and bearings and aging shaft seals, which raises oil carryover and can even lead to airend failure.
