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: multi-pass method for evaluating filtration performance (beta ratio)
- ISO 16890 / EN 779 — General ventilation air filter classification

- GB/T 6165 — Test methods for air filter performance (efficiency and resistance)
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 a pressure differential of 600 Pa
Installation Steps
- Shut down and isolate power: Switch off the compressor and confirm the unit has fully stopped.
- Open the filter housing cover: Loosen the retaining nut or clips and remove the top 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 media for damage, pleats for deformation, end caps for cracks, and gasket for aging.
- Install the new element: Slide it onto the center stud and ensure the gasket seats correctly top and bottom without skewing.
- Refit the cover: Reinstall the cover and tighten nuts 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 the 89295976 a genuine original part?
A: The 89295976 is a genuine Ingersoll Rand part manufactured to Ingersoll Rand global technical standards, designed to fit original Ingersoll Rand intake filter housings.
Q2: Which compressor models does the 89295976 fit?
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 whether your model applies, provide the machine serial number and we will match it precisely.
Q3: What is the difference between the 89295976 and the newer air filter element? Can they be interchanged?
A: The 89295976 is an older design (noted as a legacy part in DMS records); some newer models may use a different part number. Mounting dimensions and interfaces may differ, so they are not freely interchangeable. To confirm an alternative part number, provide the machine serial number.
Q4: How do I know when the air filter element needs replacing?
A: Replace it in any of three cases: (1) visual inspection shows blackened media or heavy dust accumulation; (2) operating pressure differential reaches the 500 Pa alarm value; (3) the 2,000–4,000 hour or 6–12 month service 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 and potentially airend failure.
