Ingersoll Rand 89295976 Air Filter Element

The 89295976 air filter element is a genuine Ingersoll Rand intake filter element engineered for 4–22 kW small rotary screw air compressors. Its synthetic fiber media blocks dust and particulate matter from entering the screw airend, protecting rotors, bearings, and shaft 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 restriction, straightforward installation, and stable filtration efficiency. This element is a legacy common part compatible with R, UP, V, EW, and RM-C series small rotary screw compressors, making it one of the most frequently used intake filter elements in small-machine maintenance.

• ISO 16890 / EN 779 — General ventilation air filters: classification
• 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, heavy dust loading, or differential pressure reaches 600 Pa

Installation Steps

1. Shut down and isolate power — Turn 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 surface 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 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 to ensure a gap-free seal.
8. Start-up check — Start the compressor, check for air leaks at the intake, and confirm normal operation.

FAQ

Q1: Is the 89295976 a genuine original part?

A: The 89295976 is a genuine Ingersoll Rand part manufactured to Ingersoll Rand global technical standards and fits original Ingersoll Rand intake filter housings.

Q2: Which compressor models does the 89295976 fit?

A: This element 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 rotary screw compressors. If you are unsure whether it fits your model, provide the machine serial number and we will match it precisely.

Q3: What is the difference between the 89295976 and newer intake elements? Can they be interchanged?

A: The 89295976 is a legacy design (noted as "old model" in DMS). Some newer models may use a new part number. Mounting dimensions and interfaces can differ, so they are not freely interchangeable. To confirm a replacement, provide the machine serial number for a lookup.

Q4: How do I know when to replace the intake element?

A: Replace when any of these occur: (1) visual inspection shows darkening or heavy dust loading; (2) operating differential pressure 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 intake element becomes too dirty?

A: A clogged intake element causes insufficient intake air, reduced discharge volume, higher specific power, and increased energy consumption. In severe cases, dust enters the airend, causing rotor and bearing wear, seal aging, higher oil carryover, and potentially airend failure.
