Ingersoll Rand 89295976 Air Filter Element

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

Built to Ingersoll Rand global technical standards, this element combines low initial pressure drop, straightforward installation, and stable filtration efficiency. As a legacy common part, it fits R-series, UP-series, V-series, EW-series, and RM-C-series small screw compressors — one of the most frequently replaced intake filters in Ingersoll Rand small-machine maintenance.

Note: Dimensions are reference values for this small-machine filter class; physical measurement is recommended for confirmation.

Construction Materials

• Media: Synthetic fiber filter media (imported high-efficiency paper)
• Media Weight: Approx. 80–100 g/m²
• Support: Inner metal support mesh prevents media collapse and deformation
• End Caps: Polyurethane (PU), oil- and aging-resistant
• Gasket: Polyurethane foam gasket, integrally molded with end cap
• Bonding: Polyurethane adhesive bonds end caps to media; heat-resistant, no debonding

Operating Tolerance

• Operating Temperature: Continuous: -20°C to 80°C; short-term peak: up to 100°C
• Relative Humidity: ≤95% RH, no condensation
• Collapse Pressure Resistance: ≥ 2.5 kPa overall differential
• Special Feature: Low restriction, suitable for continuous-duty environments

Service Life and Storage

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

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 — 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 blackened media, heavy dust accumulation, or differential pressure reaches 600 Pa

Installation Steps

1. Shut down and isolate 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 used 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 to remove dust and debris. Never reverse-blow a loaded filter 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 the new element onto the center mounting stud, ensuring the gasket seats correctly top and bottom without misalignment.
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, listen for air leaks at the intake, and confirm normal operation.

FAQ

Q1: Is 89295976 a genuine Ingersoll Rand part?
A: Yes, 89295976 is a genuine Ingersoll Rand spare part manufactured to Ingersoll Rand global technical standards and designed to fit original 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 rotary screw compressors. If you are unsure about your model, provide the machine serial number and we will match it precisely.

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

Q4: How do I know when to replace the air filter element?
A: Replace when: (1) visual inspection shows blackened 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 is too dirty?
A: A clogged filter restricts intake air, reducing discharge volume and raising specific power consumption and energy costs. In severe cases, dust enters the airend, causing rotor and bearing wear, seal aging, higher oil carryover, and potentially airend failure.
