Ingersoll Rand 89295976 Air Filter Element

The 89295976 air filter element is a genuine Ingersoll Rand intake filter for small rotary screw air compressors in the 4–22 kW range. Built with high-efficiency synthetic fiber media, it blocks dust and particulate matter from entering the airend, protecting rotors, bearings and shaft seals from wear and helping extend compressor service life.

As an original intake filtration component, the 89295976 is produced to Ingersoll Rand global technical standards and offers low initial resistance, straightforward installation and stable filtration efficiency. It is a legacy common part covering the R, UP, V, EW and RM-C series — one of the most frequently replaced intake filters in small Ingersoll Rand compressor maintenance.

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 beta ratio
• ISO 16890 / EN 779 — Classification of general ventilation air filters
• GB/T 14295 — Air filters
• 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): every 1,000–2,000 hours
• Replace immediately if visual inspection shows darkening or heavy dust loading, or when differential pressure reaches 600 Pa

Installation Steps

1. Shut down and isolate power: switch off the compressor and confirm the unit has fully stopped.
2. Open the filter housing cover: release the retaining nuts or clips and remove the cover.
3. Remove the old element: pull out the old 89295976 element and check whether the center gasket remains in the housing groove.
4. Clean the housing: wipe the inner wall and sealing surface with a clean cloth. Never reverse-blow a loaded element with compressed air and reuse it.
5. Inspect the new element: verify part number 89295976, check media for damage, pleats for deformation, end caps for cracks and gasket for aging.
6. Install the new element: slide it onto the center stud, ensuring the gasket seats correctly top and bottom without skewing.
7. Refit the cover: reinstall the filter cover and tighten nuts or clips evenly for a gap-free seal.
8. 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: Yes. The 89295976 is a genuine Ingersoll Rand part manufactured to Ingersoll Rand global technical standards and fits original intake filter housings.

Q2: Which compressor models use the 89295976?
A: This legacy common part covers a wide range, 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, provide the compressor serial number and we will match it precisely.

Q3: Does the 89295976 differ from newer air filter elements? Can they be interchanged?
A: The 89295976 is a legacy design; some newer models may use a different part number. Installation dimensions and interfaces may differ, so they are not freely interchangeable. Provide the serial number to confirm any superseded part.

Q4: How do I know when to replace the air filter element?
A: Replace when (1) visual inspection shows darkening or heavy dust loading; (2) operating differential pressure reaches the 500 Pa alarm value; or (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 restricts intake air, reducing discharge volume and raising specific power and energy consumption. In severe cases, dust enters the airend, wearing rotors, bearings and shaft seals, increasing oil carryover and potentially causing airend failure.
