Ingersoll Rand 89295976 Air Filter Element — Genuine Small Rotary Screw Air Compressor Intake Filter

I. Product Overview

89295976 Air Filter Element is a genuine Ingersoll Rand original intake filter element for small screw air compressors, specifically designed and manufactured for 4~22kW small screw air compressors. This filter element uses high-efficiency synthetic fiber filter media to effectively block dust and particulate matter in the air from entering the screw main unit, protecting the rotors, bearings, and oil seals, and extending the service life of the air compressor.

As an Ingersoll Rand original intake filtration accessory, 89295976 is produced in strict accordance with Ingersoll Rand's globally unified technical standards, featuring low initial resistance, easy installation, and stable filtration efficiency. This filter element is a common part for older machine models, compatible with multiple small screw air compressors including the R series, UP series, V series, EW series, and RM-C series, and is one of the most commonly used intake filter elements in the maintenance of Ingersoll Rand small machines.

7. Applicable Standards

• ISO 5011: Inlet air filters for internal combustion engines and compressors — performance testing (efficiency and dust holding capacity)
• ISO 16889: Hydraulic fluid power filters — determination of filtration ratio β value
• ISO 16890 / EN 779: Classification of air filters for general ventilation
• GB/T 14295: Air filters
• GB/T 6165: Test methods for air filter performance (efficiency and resistance)

IV. Standard Maintenance and Installation Steps

Replacement Interval

• Standard operating conditions: every 2000~4000 hours or 6~12 months (whichever comes first)
• High-dust conditions (construction sites, mines, woodworking shops, etc.): every 1000~2000 hours
• Replace immediately when visual inspection reveals blackened filter media, severe dust accumulation, or a pressure differential reaching 600 Pa

Installation Steps

1. Shut down and disconnect power: Turn off the air compressor power supply and confirm the unit has completely stopped running.
2. Open the air filter cover: Loosen the fixing nuts or clips on the air filter cover and remove the upper cover.
3. Remove the old filter element: Pull out the old 89295976 filter element and check whether the center seal ring remains in the housing groove.
4. Clean the filter housing: Wipe the inner wall and sealing surface of the filter housing with a clean cloth to remove dust and debris. It is strictly prohibited to blow back a dust-laden filter element with compressed air and reuse it.
5. Inspect the new filter element: Verify the part number 89295976, and check the filter media for damage, the pleats for deformation, the end caps for cracks, and the seal ring for aging.
6. Install the new filter element: Insert the new filter element onto the center fixing stud, ensuring the seal ring fits properly on both top and bottom without skewing.
7. Reinstall the upper cover: Put the filter cover back on, tighten the nuts or fasten the clips evenly, and ensure a tight seal with no gaps.
8. Start-up inspection: Start the air compressor, check for air leakage sounds at the intake, and observe whether it runs normally.

V. Frequently Asked Questions

Q1: Is 89295976 a genuine original part?

A: 89295976 is a genuine Ingersoll Rand original accessory, manufactured in strict accordance with Ingersoll Rand's global unified technical standards, and fits Ingersoll Rand original intake filter housings.

If you are unsure whether it fits your model, please provide the unit serial number (Serial Number) and we will match it precisely for you.

Q3: What is the difference between 89295976 and the new air filter element? Are they interchangeable?

A: 89295976 is an old-model design, and some newer models may have switched to a new part number filter element. The two may differ in installation dimensions and connections and must not be interchanged at will. To confirm a replacement model, please provide the unit serial number for verification.

Q4: How do I determine whether the air filter element needs replacement?

A: Replacement is required in three situations: ① Visual inspection reveals blackened filter media or severe dust accumulation; ② The operating pressure differential reaches the alarm value of 500 Pa; ③ The replacement interval of 2000~4000 hours or 6~12 months is reached.

Q5: What impact does a heavily soiled air filter element have?

A: A clogged air filter element will cause insufficient intake, reduced discharge volume, increased specific power, and higher energy consumption. In severe cases, dust entering the main unit will cause rotor and bearing wear and oil seal aging, leading to increased oil content in the discharge and even scrapping of the main unit.
