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 and manufactured for N55 and N75 series screw air compressors. Using high-efficiency synthetic/fiberglass media, it blocks dust and airborne particles from entering the screw airend, protecting rotors, bearings, and oil seals from wear and extending compressor service life.

The 54672530 is a large cylindrical pleated element: 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. The HiFi Filter cross-reference is SA17281.

Maintenance and Installation

Replacement Schedule

• Standard conditions: every 4,000 hours or 8–12 months, whichever comes first
• High-dust conditions: every 2,000–3,000 hours
• Replace immediately if visual inspection shows darkening or heavy dust loading, or if differential pressure reaches 900 Pa

Installation Steps

1. Shut down and isolate: Turn off the main power, apply lockout/tagout (LOTO), and confirm the machine has fully stopped.
2. Open the filter housing cover: Loosen the retaining bolts or clips and remove the cover.
3. Remove the old element: Pull out the old 54672530 element and check whether the seal remains in the housing groove.
4. Clean the housing: Wipe the inner wall and sealing surface 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 the red seal for aging.
6. Install the new element: Place it vertically into the center of the housing, ensuring both seals seat correctly with no misalignment.
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 around the filter housing.
