Ingersoll Rand 89295976 Air Filter Element

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

As an original intake filtration component, 89295976 is produced to Ingersoll Rand global technical standards. It offers low initial pressure drop, 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 replaced intake filters in small-machine maintenance.

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 filter 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 accumulation, or differential pressure 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. 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 seals.
6. Install the new element: Insert onto the center stud, ensuring the seal seats correctly on both sides without skewing.
7. Refit the cover: Reinstall the cover and tighten nuts 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 original part?

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

Q2: Which compressor models does 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, EW5-22 and other 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? Are they interchangeable?

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

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

A: Replace in three cases: (1) visual inspection shows darkening or heavy dust; (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 air filter element is too dirty?

A: A clogged element causes insufficient intake, 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 even airend failure.
