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

Product Overview

The 54672530 air filter element is a genuine Ingersoll Rand inlet filter designed for N55 and N75 series screw air compressors. Its high-efficiency synthetic/glass-fiber media captures airborne dust and particulate before it reaches the airend, helping protect rotors, bearings and shaft seals from abrasive 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-referenced to HiFi Filter SA17281 and is compatible with several Atlas Copco part numbers.

Maintenance & Installation

Replacement interval: every 4000 hours or 8–12 months (whichever comes first) under standard conditions; every 2000–3000 hours in high-dust environments. Replace immediately if the element is visibly darkened or heavily loaded, or if the differential pressure reaches 900 Pa.

1. Isolate and lock out the compressor main power (LOTO); confirm the unit has fully stopped.
2. Release the filter housing cover bolts or clamps and remove the cover.
3. Withdraw the old 54672530 element; check that no seal remains in the housing groove.
4. Wipe the housing interior and sealing surfaces clean.
5. Inspect the new element: verify part number 54672530, check media for damage, end caps for cracks and red seals for aging.
6. Insert the new element vertically into the housing center, ensuring both seals seat correctly without skewing.
7. Refit the cover and tighten bolts or clamps evenly.
8. Start the compressor and check for air leaks at the filter housing.
