Ingersoll Rand 89295976 Air Filter Element

Genuine Ingersoll Rand 89295976 air filter element — the original intake filter for small rotary screw air compressors from 4 to 22 kW. Engineered with high-efficiency synthetic fiber media, it blocks dust, dirt, and particulate matter from entering the screw airend, protecting rotors, bearings, and oil seals from wear and extending compressor service life.

As a genuine Ingersoll Rand intake filtration component, the 89295976 is manufactured to Ingersoll Rand global technical standards. It offers low initial pressure drop, 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 screw compressors — one of the most frequently replaced intake filters in Ingersoll Rand small compressor maintenance.

• ISO 16890 / EN 779 — Air filters for general ventilation: classification
• GB/T 14295 — Air filters
• GB/T 6165 — Test methods for air filter performance (efficiency and resistance)

Maintenance & 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 media is blackened, heavily loaded, or pressure differential reaches 600 Pa

Installation Steps

1. Shut down and disconnect power: turn off the compressor and confirm it has fully stopped.
2. Open the filter housing cover: loosen 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 walls and sealing surfaces with a clean cloth. Never reverse-blow a loaded element with compressed air for reuse.
5. Inspect the new element: verify part number 89295976; check media for damage, pleat deformation, cracked end caps, or aged gaskets.
6. Install the new element: slide onto the center stud, ensuring the gasket seats correctly top and bottom without skewing.
7. Refit the cover: replace the cover and tighten nuts or clips evenly to ensure a gap-free seal.
8. Start-up check: start the compressor and listen for air leaks at the intake; confirm normal operation.

Frequently Asked Questions

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, designed for 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 screw compressors. If you are unsure about your model, provide the compressor 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. Installation dimensions and interfaces can differ, so they are not freely interchangeable. To confirm a replacement part number, provide the compressor serial number for verification.

Q4: How do I know when to replace the air filter element?
A: Replace when: ① visual inspection shows blackened or heavily loaded media; ② operating pressure differential reaches the 500 Pa alarm value; ③ the 2,000–4,000 hour or 6–12 month interval is reached.

Q5: What happens if the air filter is too dirty?
A: A clogged element restricts intake air, reducing discharge volume and increasing specific power and energy consumption. In severe cases, dust enters the airend, causing rotor and bearing wear and oil seal aging, which raises oil carryover and can lead to airend failure.
