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

Product Overview

The Ingersoll Rand 89295976 air filter element is a genuine intake filter for small screw air compressors in the 4–22 kW range. It uses high-efficiency synthetic fiber media to block dust and airborne particles before they reach the screw airend, protecting rotors, bearings and shaft seals from wear and extending compressor service life.

As an original Ingersoll Rand intake filtration part, the 89295976 is built to Ingersoll Rand global technical standards. It offers low initial resistance, straightforward installation and stable filtration efficiency. This element is a legacy common part covering R, UP, V, EW and RM-C series small screw compressors, making it one of the most frequently ordered intake filters in small-machine maintenance.

Standards Referenced

• ISO 5011 — intake 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 and Installation

Replacement Interval

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

Installation Steps

1. Shut down and isolate: switch off the compressor 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 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 and reuse it.
5. Inspect the new element: verify part number 89295976, check for media 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 the 89295976 a genuine original part?
A: Yes. The 89295976 is a genuine Ingersoll Rand part manufactured to Ingersoll Rand global technical standards and fits the original intake filter housing.

Q2: Which compressor models does the 89295976 fit?
A: This is a legacy common part with broad coverage, 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 your machine serial number and we will match it precisely.

Q3: What is the difference between the 89295976 and newer air filter elements? Can they be interchanged?
A: The 89295976 is the legacy design. Some newer models may use a new part number. Mounting dimensions and interfaces can differ, so they are not freely interchangeable. Provide your serial number to confirm any superseding part.

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 differential pressure reaches the 500 Pa alarm value, or (3) the 2000–4000 hour / 6–12 month interval is reached.

Q5: What happens if the air filter element is too dirty?
A: A clogged element starves the compressor of intake air, reducing discharge volume and raising specific power and energy consumption. In severe cases, dust enters the airend, wearing rotors and bearings and aging shaft seals, which can raise oil carryover and even lead to airend failure.
