Ingersoll Rand 54672530 Air Filter Element | N55/N75 Screw Compressor

Product Overview

The 54672530 air filter element is a genuine Ingersoll Rand intake filter for N55 and N75 series screw air compressors. It uses high-efficiency synthetic fiberglass media to block dust and particulate matter from entering the screw airend, protecting rotors, bearings and shaft seals from wear and extending compressor service life.

This large cylindrical pleated element measures approximately 247 mm outside diameter and 365 mm overall height, with a red polyurethane (PU) end-cap seal. It is also cross-compatible with several Atlas Copco part numbers and carries the HiFi Filter cross-reference SA17281.

Technical Specifications

Filtration Performance

Operating Conditions

• Operating temperature: -20°C to 80°C continuous; 100°C short-term peak
• Relative humidity: ≤95% RH, no condensation
• Collapse pressure resistance: ≥4.0 kPa
• Features: low resistance, high dust holding capacity, suitable for continuous industrial duty

Service Life and Storage

• Service life: approx. 4000 hours (8–12 months) under standard conditions; 2000–3000 hours in high-dust environments
• Shelf life: 36 months in original sealed packaging, dry ambient conditions

Standards

• ISO 5011 — inlet air filter performance testing for internal combustion engines and compressors
• ISO 16890 / EN 779 — general ventilation air filter classification
• GB/T 14295 — air filters
• GB/T 6165 — air filter performance test methods

Maintenance and Installation

Replacement Interval

• Standard conditions: every 4000 hours or 8–12 months, whichever comes first
• High-dust conditions: every 2000–3000 hours
• Replace immediately if the media turns black, shows heavy dust loading, or the pressure differential reaches 900 Pa

Installation Steps

1. Shut down and isolate: switch off the main power, apply lockout/tagout (LOTO), and confirm the unit has fully stopped.
2. Open the filter housing: release the bolts or clips and remove the cover.
3. Remove the old element: pull out the old 54672530 element and check whether the old 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.
5. Inspect the new element: verify part number 54672530; check for media damage, cracked end caps, or aged red seals.
6. Install the new element: seat it vertically in the center of the housing, ensuring both seals fit correctly without tilting.
7. Refit the cover: reinstall the cover and tighten bolts or clips evenly.
8. Start-up check: start the compressor and listen for air leaks at the filter housing.

Frequently Asked Questions

Q1: Is the 54672530 a genuine OEM part?
