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 designed for Ingersoll Rand 4–22 kW small rotary screw air compressors. It uses high-efficiency synthetic fiber media to block dust, dirt, and airborne particles from entering the screw airend, protecting rotors, bearings, and oil seals from wear and extending compressor service life.

As a factory intake filtration component, the 89295976 is manufactured to Ingersoll Rand global technical standards. It features low initial pressure drop, straightforward installation, and stable filtration efficiency. This element is a legacy common part compatible with R, UP, V, EW, and RM-C series small screw compressors, making it one of the most frequently replaced intake filters in Ingersoll Rand small-machine maintenance.

• Collapse pressure resistance: ≥2.5 kPa
• Special features: low resistance, suitable for continuous operation

Service Life and Storage

• Service life: approx. 2,000–4,000 hours (6–12 months) under standard conditions; 1,000–2,000 hours in high-dust environments
• Shelf life: 36 months in sealed original packaging, stored in a dry environment at room temperature

Standards

• ISO 5011 — Inlet air cleaning equipment for internal combustion engines and compressors: performance testing
• ISO 16889 — Hydraulic fluid power filters: determination of beta ratio
• 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 dark media, heavy dust accumulation, or differential pressure reaches 600 Pa

Installation Steps

1. Shut down and disconnect power: turn off the compressor and confirm it 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 walls and sealing surfaces 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, ensuring the gasket seats evenly on both sides 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 and check for air leaks at the intake; confirm normal operation.

Frequently Asked Questions

Q1: Is the 89295976 a genuine OEM part?
A: Yes, 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: As a legacy common part, it 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 machine serial number and we will match it precisely.

Q3: How is the 89295976 different from newer air filter elements? Can they be interchanged?
A: The 89295976 is a legacy design (noted as "old version" in DMS). Some newer models may use a new part number. Mounting dimensions and interfaces may differ, so they are not freely interchangeable. To confirm a replacement part, provide the machine serial number for a lookup.

Q4: How do I know when to replace the air filter element?
A: Replace when: (1) visual inspection shows dark media or heavy dust; (2) operating differential pressure 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, which can raise oil carryover and even lead to airend failure.
