Ingersoll Rand 89295976 Air Filter Element | R4i–R11i, UP5, V15/V22

Product Overview

The Ingersoll Rand 89295976 air filter element is a genuine OEM intake filter engineered for Ingersoll Rand 4–22 kW small rotary screw compressors. Manufactured to Ingersoll Rand global technical standards, it uses high-efficiency synthetic fiber media to block dust, dirt, and airborne particles before they reach the airend, protecting rotors, bearings, and oil seals from premature wear.

As a legacy common part, 89295976 fits a broad range of R, RM-C, UP, V, VSD, and EW series small screw compressors. It is one of the most frequently replaced intake filters in Ingersoll Rand small compressor maintenance programs.

Standards

• ISO 5011: Inlet air cleaning equipment for internal combustion engines and compressors — performance testing (efficiency and dust capacity)
• ISO 16889: Hydraulic fluid power filters — multi-pass method for evaluating filtration performance (beta ratio)
• ISO 16890 / EN 779: Air filters for general ventilation — classification
• GB/T 14295: Air filters
• GB/T 6165: Test methods for air filters — 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, etc.): every 1,000–2,000 hours
• Replace immediately if visual inspection shows darkening, heavy dust accumulation, or if pressure differential reaches 600 Pa

Installation Steps

1. Shut down and disconnect 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 seal remains in the housing groove.
4. Clean the housing: Wipe the inner walls and sealing surface with a clean cloth to remove dust and debris. Never reuse a dust-loaded element after blow-back cleaning.
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 the new element onto the center stud, ensuring the gasket seats evenly top and bottom without skewing.
7. Replace the cover: Refit the filter 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 89295976 a genuine OEM part?

A: Yes. 89295976 is a genuine Ingersoll Rand spare part manufactured to Ingersoll Rand global technical standards and designed to fit original Ingersoll Rand intake filter housings.

Q2: Which compressor models does 89295976 fit?

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, and EW5-22 small screw compressors. If you are unsure about your model, provide the serial number and we will match it precisely.

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

A: 89295976 is the legacy design (marked "old model" in DMS). Some newer compressor models may use a different filter part number. Installation dimensions and interfaces may differ, so they are not freely interchangeable. To confirm a replacement, please provide the compressor serial number.

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

A: Replace when: (1) visual inspection shows darkening or heavy dust accumulation; (2) operating pressure differential reaches the 500 Pa alarm value; or (3) the 2,000–4,000 hour or 6–12 month interval is reached.

Q5: What happens if the air filter element 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, leading to higher oil carryover or even catastrophic airend failure.
