Ingersoll Rand 89295976 Air Filter Element | Small Rotary Screw Compressor OEM Part

Product Overview

89295976 is a genuine Ingersoll Rand air filter element (air intake filter) engineered for small rotary screw air compressors in the 4–22 kW range. It uses high-efficiency synthetic fiber media to block dust, particulates and airborne contaminants from entering the screw airend, protecting rotors, bearings and shaft seals from wear and helping extend compressor service life.

As an original Ingersoll Rand intake filtration component, 89295976 is built to Ingersoll Rand global technical standards. It is a legacy common part covering a wide range of small screw compressors, including R series, UP series, V series, EW series and RM-C series models — one of the most frequently replaced intake filter elements in small-machine maintenance.

• Relative humidity: ≤95% RH, no condensation
• Collapse pressure resistance: ≥2.5 kPa overall differential
• Service life: approx. 2,000–4,000 hours (6–12 months) under standard conditions; 1,000–2,000 hours in high-dust environments
• Shelf life: 36 months in unopened packaging, dry ambient conditions

Standards Referenced

• ISO 5011 — intake filter performance testing (efficiency and dust capacity)
• ISO 16889 — determination of beta ratio for hydraulic filters
• ISO 16890 / EN 779 — air filter classification for general ventilation
• GB/T 14295 — air filters
• GB/T 6165 — air filter performance test methods (efficiency and resistance)

Maintenance & Installation

Replacement Intervals

• 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 the media is visibly blackened, heavily loaded, or differential pressure reaches 600 Pa

Installation Steps

1. Shut down and isolate: switch off compressor power and confirm the unit has fully stopped.
2. Open the filter housing: release the retaining nut 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, pleat deformation, cracked end caps or aged gaskets.
6. Install: slide the new element onto the center stud, ensuring the gasket seats correctly top and bottom without skewing.
7. Refit the cover: reinstall the cover and tighten the nut 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.

Frequently Asked Questions

Q1: Is 89295976 a genuine original part?
A: Yes. 89295976 is a genuine Ingersoll Rand part produced to Ingersoll Rand global technical standards and fits original Ingersoll Rand intake filter housings.

Q2: Which compressor models use 89295976?
A: This legacy common element 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 screw compressors. If you are unsure, provide the compressor serial number and we will match it precisely.

Q3: Can 89295976 be replaced by a newer filter number?
A: 89295976 is a legacy design, and some newer models may use a different filter number. Mounting dimensions and interfaces can differ, so they are not freely interchangeable. Provide the serial number to confirm any supersession.

Q4: How do I know when to replace the air filter element?
A: Replace when: (1) the media is visibly blackened or heavily loaded; (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 is left 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.
