Ingersoll Rand 89295976 Air Filter Element — Genuine Intake Filter for Small Screw Compressors

The 89295976 air filter element is a genuine Ingersoll Rand intake filter designed for small rotary screw compressors in the 4–22 kW range. Its synthetic fiber media captures airborne dust and particles before they reach the airend, helping protect rotors, bearings and shaft seals from premature wear.

As an original Ingersoll Rand service part, the 89295976 is manufactured to Ingersoll Rand global technical standards. It is a legacy common part used across R, UP, V, EW and RM-C series small compressors, making it one of the most frequently replaced intake filters in routine maintenance.

• Shelf life: 36 months in sealed packaging, dry, room-temperature storage

Standards

• ISO 5011 — Inlet air cleaning equipment for internal combustion engines and compressors
• ISO 16889 — Hydraulic fluid power filters, beta ratio determination
• ISO 16890 / EN 779 — General ventilation air filters
• GB/T 14295 — Air filters
• GB/T 6165 — Test methods for air filter performance

Maintenance and Installation

Replacement intervals

• Standard conditions: every 2000–4000 hours or 6–12 months, whichever comes first
• High-dust conditions (construction sites, mines, woodworking): every 1000–2000 hours
• Replace immediately if the media is blackened, heavily loaded, or pressure drop reaches 600 Pa

Installation steps

1. Shut down and lock out: switch off compressor power and confirm the unit has fully stopped.
2. Open the filter housing: loosen the retaining nut or clips and remove the cover.
3. Remove the old element: pull out the old 89295976 element and check that the center seal is not left in the housing groove.
4. Clean the housing: wipe the inner walls and sealing surfaces with a clean cloth. Do not blow out and reuse a loaded element.
5. Inspect the new element: verify part number 89295976, check for media damage, pleat deformation, cracked end caps or aged seals.
6. Install the new element: slide it onto the center stud, ensuring the seal sits correctly top and bottom without skewing.
7. Refit the cover: replace the cover and tighten the nut or clips evenly to ensure 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 the 89295976 a genuine Ingersoll Rand part?
A: Yes, it is a genuine Ingersoll Rand service 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 fits a wide range of models, 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, EW5-22 and other small screw compressors. If you are unsure, provide the compressor serial number for accurate matching.

Q3: How does it differ from newer air filter elements? Can they be interchanged?
A: The 89295976 is a legacy design (marked "old version" in DMS). Some newer models may use a different part number. Mounting dimensions and connections may differ, so they are not freely interchangeable. Provide the serial number to confirm the correct replacement.

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 drop reaches the 500 Pa alarm; or (3) the 2000–4000 hour or 6–12 month interval is reached.

Q5: What happens if the air filter is too dirty?
A: A clogged element restricts intake, reduces discharge volume, raises specific power and energy consumption, and in severe cases allows dust into the airend, causing rotor and bearing wear, seal aging, higher oil carryover, and potentially catastrophic compressor failure.
