Ingersoll Rand 89295976 Air Filter Element

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

As an original Ingersoll Rand intake filtration component, 89295976 is manufactured to Ingersoll Rand's global technical standards. It offers low initial pressure drop, straightforward installation, and stable filtration efficiency. This element is a legacy common part compatible with R series, UP series, V series, EW series, and RM-C series small rotary screw compressors — one of the most frequently replaced intake filters in small Ingersoll Rand machines.

• GB/T 14295 — Air filters
• GB/T 6165 — Test methods for air filter performance (efficiency and resistance)

Standard 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 blackened media, heavy dust accumulation, or pressure drop 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 air 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 surfaces with a clean cloth to remove dust and debris. Never reverse-blow a loaded element with compressed air and reuse it.
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: Slide the new element onto the center stud, ensuring the seal seats correctly top and bottom without skewing.
7. Replace the cover: Refit the 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.

FAQ

Q1: Is 89295976 a genuine original part?

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

Q2: Which compressor models is 89295976 compatible with?

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, and EW5-22 small rotary screw compressors. If you are unsure whether it fits your machine, provide the serial number and we will match it precisely.

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

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

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

A: Replace in three cases: (1) visual inspection shows blackened media or heavy dust; (2) operating pressure drop 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 and seal aging, leading to higher oil carryover and potentially airend failure.
