Ingersoll Rand 89295976 Air Filter Element

The 89295976 air filter element is a genuine Ingersoll Rand inlet filter for small rotary screw air compressors in the 4–22 kW class. Built with high-efficiency synthetic fiber media, it captures dust and airborne particles before they reach the airend, helping protect rotors, bearings and shaft seals from abrasive wear.

As an original IR inlet filtration part, 89295976 follows Ingersoll Rand's global technical standard. It is a long-running common part covering the R, UP, V, EW and RM-C series — one of the most frequently replaced inlet filters in small screw compressor maintenance. For export buyers, we confirm fitment by serial number before shipment.

Standards Referenced

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

Maintenance & Installation Steps

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 the media appears blackened or heavily loaded, 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: 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 wall and sealing face 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, pleats for deformation, end caps for cracks and gasket for aging.
6. Install the new element: Slide it onto the center stud and ensure the gasket seats evenly top and bottom without tilting.
7. Refit the cover: Reinstall 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 inlet and confirm normal operation.

Frequently Asked Questions

Q1: Is 89295976 a genuine part?
A: Yes, 89295976 is a genuine Ingersoll Rand part manufactured to IR's global technical standard and designed for the original IR inlet filter housing.

Q2: Which compressor models does 89295976 fit?
A: As a legacy common part, it 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 machine serial number and we will confirm fitment.

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

Q4: How do I know when to replace the air filter element?
A: Three indicators: (1) visible blackening or heavy dust loading; (2) differential pressure reaching the 500 Pa alarm value; (3) reaching the 2,000–4,000 hour or 6–12 month interval.

Q5: What happens if the air filter element is too dirty?
A: A clogged element restricts inlet air, reducing discharge volume and raising specific power consumption. In severe cases, dust enters the airend, causing rotor and bearing wear and seal aging — leading to higher oil carryover or even airend failure.
