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

Product Overview

The 89295976 air filter element is a genuine Ingersoll Rand intake filter designed 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.

As an original intake filtration component, the 89295976 is manufactured 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 series, UP series, V series, EW series and RM-C series small screw compressors — one of the most frequently replaced intake filters in small-machine maintenance.

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

Material Construction

• 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: PU adhesive bonds end caps to media; heat-resistant, no debonding

Operating Tolerance

• Operating temperature: Continuous -20°C to 80°C; short-term up to 100°C
• Relative humidity: ≤95% RH, no condensation
• Collapse pressure resistance: Overall ≥ 2.5 kPa differential
• Special features: Low resistance, suitable for continuous-duty environments

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 original sealed packaging, dry ambient temperature

Standards Referenced

• 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: Air filters for general ventilation — 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 darkened media, heavy dust loading, or differential pressure reaching 600 Pa

Installation Steps

1. Shut down and isolate power: Switch 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 gasket remains in the housing groove.
4. Clean the housing: Wipe the inner wall and sealing surface with a clean cloth. Never blow compressed air through a loaded element 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 top and bottom without skewing.
7. Refit the cover: Reinstall the cover and tighten the nut or clips evenly for 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 the 89295976 a genuine original part?
A: Yes. The 89295976 is a genuine Ingersoll Rand component manufactured to Ingersoll Rand global technical standards and fits the original intake filter housing.

Q2: Which compressor models does the 89295976 fit?
A: This legacy common part covers a wide range: 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 rotary screw compressors. If you are unsure, provide the compressor serial number and we will match it precisely.

Q3: How does the 89295976 differ from newer air filter elements? Can they be interchanged?
A: The 89295976 is the legacy design; some newer models may use a different part number. Mounting dimensions and interfaces can differ, so they are not freely interchangeable. Provide the serial number to confirm any superseded part.

Q4: How do I know when to replace the air filter element?
A: Replace when: (1) visual inspection shows darkened media or heavy dust loading; (2) operating differential pressure reaches the 500 Pa alarm value; or (3) the 2,000–4,000 hour / 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 raising specific power and energy consumption. In severe cases, dust enters the airend, causing rotor and bearing wear, seal aging, higher oil carryover, and potentially airend failure.
