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

4. Standard Maintenance and Installation Steps
Replacement Interval
- Standard conditions: every 2000–4000 hours or 6–12 months, whichever comes first
- High-dust conditions (construction sites, mines, woodworking shops, etc.): every 1000–2000 hours
- Replace immediately if visual inspection shows blackened media, heavy dust accumulation, or pressure differential reaches 600 Pa
Installation Steps
- Shut down and disconnect power: Turn off the compressor power and confirm the unit has completely stopped.
- Open the air filter 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 wall and sealing surface with a clean cloth to remove dust and debris. Never reverse-blow a loaded element with compressed air for reuse.
- Inspect the new element: Verify part number 89295976; check media for damage, pleats for deformation, end caps for cracks, and seal for aging.
- Install the new element: Slide the new element onto the center stud, ensuring the seal seats correctly on both sides without misalignment.
- Reinstall the cover: Replace the filter 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 verify normal operation.
5. Frequently Asked Questions
Q1: Is 89295976 a genuine OEM part?
A: Yes, 89295976 is a genuine Ingersoll Rand replacement part manufactured to Ingersoll Rand global technical standards and designed for Ingersoll Rand original intake filter housings.
Q2: Which compressor models does 89295976 fit?
A: This element 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, EW5-22, and other small screw compressors. If you are unsure about your model, provide the serial number and we will match it precisely.
Q3: What is the difference between 89295976 and newer air filter elements? Can they be interchanged?
A: 89295976 is the legacy design (noted as "old model" in DMS). Some newer models may use a different part number. Mounting dimensions and interfaces may differ, so they are not freely interchangeable. To confirm a replacement part number, please provide the compressor serial number.
Q4: How do I know when to replace the air filter element?
A: Replace when any of the following occurs: (1) visual inspection shows blackened media or heavy dust; (2) operating differential reaches the alarm value of 500 Pa; (3) the 2000–4000 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 air, reduced discharge volume, higher specific power, and increased energy consumption. In severe cases, dust enters the airend, causing rotor and bearing wear and oil seal aging, leading to higher oil carryover and even airend failure.
