Ingersoll Rand 54672530 Air Filter Element — N55/N75 Screw Compressor Intake Filter

Product Overview

The 54672530 air filter element is a genuine Ingersoll Rand intake filter designed for N55 and N75 series screw air compressors. Its synthetic glass-fiber media captures airborne dust and particulate before it reaches the airend, protecting rotors, bearings, and shaft seals from abrasive wear and extending compressor service life.

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

• Collapse pressure resistance: ≥4.0 kPa differential
• 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 storage

Standards Referenced

• ISO 5011 — intake 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 appears blackened or heavily loaded, or if differential pressure reaches 900 Pa

Installation Steps

1. Shut down and isolate: switch off main power, apply lockout/tagout (LOTO), and confirm the machine has fully stopped.
2. Open the filter housing: release the cover bolts or clamps and remove the cover.
3. Remove the old element: withdraw the old 54672530 element and check whether the gasket has remained 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 media for damage, end caps for cracks, and red seals for aging.
6. Install the new element: seat it vertically in the center of the housing, ensuring both seals contact correctly without misalignment.
7. Refit the cover: reinstall the cover and tighten bolts or clamps evenly.
8. Start-up check: start the compressor and listen for air leakage at the filter housing.
