Ingersoll Rand 89295976 Air Filter Element | Small Screw Compressor OEM Part

Product Overview

The 89295976 air filter element is a genuine Ingersoll Rand intake filter designed for 4–22 kW small screw air compressors. Built with high-efficiency synthetic fiber media, it blocks dust and airborne particles from entering the airend, protecting rotors, bearings and shaft seals from wear and extending compressor service life.

As an original Ingersoll Rand intake filtration part, the 89295976 is manufactured to Ingersoll Rand global technical standards and 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, making it one of the most frequently replaced intake filters in small-machine maintenance.

• Effective filtration area: approx. 0.5–0.8 m² (pleated media)
• Pleats / pleat spacing: approx. 30–40 pleats, approx. 8–10 mm spacing
• Mounting: center through-hole, stud-fixed installation
• Sealing: polyurethane (PU) end-cap gasket, double-sided seal

Dimensions are reference values for this class of small-machine air filter element; physical measurement is recommended for confirmation.

Material Construction

• Media: synthetic fiber media (imported high-efficiency filter paper)
• Media weight: approx. 80–100 g/m²
• Support: inner metal support mesh prevents media collapse
• End caps: polyurethane (PU), oil and aging resistant
• Gasket: polyurethane foam gasket, integrally molded with end cap
• Bonding: polyurethane adhesive, temperature resistant, no debonding

Operating Conditions

• Operating temperature: continuous -20°C to 80°C; short-term up to 100°C
• Relative humidity: ≤95% RH, no condensation
• Collapse pressure resistance: ≥2.5 kPa overall
• Special feature: low resistance, suitable for continuous operation

Service Life and Maintenance

• 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 at room temperature

Standards

• ISO 5011: inlet air filter performance testing for internal combustion engines and compressors (efficiency and dust capacity)
• ISO 16889: determination of beta ratio for hydraulic filters
• ISO 16890 / EN 779: classification of general ventilation air filters
• 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 or heavily loaded media, or if differential pressure reaches 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: release 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 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 gaskets.
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 and listen for air leaks at the intake; confirm normal operation.

FAQ

Q1: Is the 89295976 a genuine original part?
A: Yes. The 89295976 is a genuine Ingersoll Rand part manufactured to Ingersoll Rand global technical standards and fits original Ingersoll Rand intake filter housings.

Q2: Which compressor models does the 89295976 fit?
A: This legacy common part covers a wide range, 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 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? Are they interchangeable?
A: The 89295976 is a legacy design; some newer models may use a different element number. Installation dimensions and interfaces can differ, so they are not freely interchangeable. Provide the serial number to confirm any superseding part.

Q4: How do I know when to replace the air filter element?
A: Replace when: (1) visual inspection shows darkened or heavily loaded media; (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 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, wearing rotors and bearings and aging shaft seals, which can increase oil carryover and even lead to airend failure.
