Ingersoll Rand 89295976 Air Filter Element
Product Overview
89295976 is a genuine Ingersoll Rand air filter element for small screw air compressors in the 4–22 kW range. It uses high-efficiency synthetic fiber media to block dust, dirt, and particulate matter from entering the screw airend, protecting rotors, bearings, and shaft seals from wear and extending compressor service life.
As an original Ingersoll Rand intake filtration part, 89295976 is built to Ingersoll Rand global technical standards, offering low initial restriction, 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 screw compressors, making it one of the most frequently used intake filter elements in small-machine maintenance.

7. Applicable Standards
- ISO 5011: Inlet air cleaning equipment for internal combustion engines and compressors — performance testing (efficiency and dust capacity)
- ISO 16889: Hydraulic fluid power filters — determination of filtration ratio β
- ISO 16890 / EN 779: Air filters for general ventilation — classification

- GB/T 6165: Methods for testing air filter performance (efficiency and resistance)
Standard Maintenance and Installation Steps
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, etc.): every 1,000–2,000 hours
- Replace immediately if visual inspection shows blackened media, heavy dust accumulation, or differential pressure reaches 600 Pa
Installation Steps
- Shut down and disconnect power: Turn off the compressor power 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 gasket 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 and reuse it.
- Inspect the new element: Verify part number 89295976; check for media damage, pleat deformation, cracked end caps, or aged gaskets.
- Install the new element: Slide the new element onto the center stud, ensuring the gasket seats correctly top and bottom without misalignment.
- Refit the cover: Reinstall 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 confirm normal operation.
Frequently Asked Questions
Q1: Is 89295976 a genuine original part?
A: 89295976 is a genuine Ingersoll Rand part manufactured to Ingersoll Rand global technical standards and fits original Ingersoll Rand 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? Are they interchangeable?
A: 89295976 is a legacy design (noted as "old version" in DMS). Some newer models may use a new part number. Mounting dimensions and interfaces may differ, so they are not freely interchangeable. To confirm a replacement part number, provide the compressor serial number for a lookup.
Q4: How do I know when to replace the air filter element?
A: Replace in three cases: ① visual inspection shows blackened media or heavy dust accumulation; ② operating differential pressure reaches the 500 Pa alarm value; ③ the 2,000–4,000 hour or 6–12 month replacement 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, causing rotor and bearing wear and seal aging, leading to higher oil carryover or even airend failure.
