Ingersoll Rand 89295976 Air Filter Element
Product Overview
The 89295976 air filter element is a genuine Ingersoll Rand inlet air filter designed for small rotary screw air compressors in the 4–22 kW range. Manufactured with high-efficiency synthetic fiber media, it blocks 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 inlet filtration component, the 89295976 is produced to Ingersoll Rand global technical standards and offers low initial resistance, 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 rotary screw compressors, making it one of the most frequently replaced inlet filters in Ingersoll Rand small compressor 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

- GB/T 14295: Air filters
- GB/T 6165: Test methods for air filters — performance (efficiency and resistance)
Standard 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, 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 supply and confirm the unit has fully stopped.
- Open the filter housing cover: Loosen the retaining nut or clips on the air filter cover and remove the top 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 of the filter housing 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, end-cap cracks, or seal aging.
- Install the new element: Slide the new element onto the center mounting stud, ensuring the seal sits flush top and bottom without skewing.
- Replace the cover: Refit 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 inlet, and confirm normal operation.
Frequently Asked Questions
Q1: Is the 89295976 a genuine original part?
A: The 89295976 is a genuine Ingersoll Rand original spare part, manufactured to Ingersoll Rand global technical standards and designed to fit original Ingersoll Rand inlet filter housings.
Q2: Which compressor models does the 89295976 fit?
A: This element is a legacy common part with broad model 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 rotary screw compressors. If you are unsure whether it fits your model, provide the serial number and we will match it precisely.
Q3: What is the difference between the 89295976 and 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 new part number element. Installation dimensions and interfaces may differ, so they are not freely interchangeable. To confirm a replacement part number, provide the compressor serial number for lookup.
Q4: How do I know when to replace the air filter element?
A: Replace in any of 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 air, 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.
