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

Product Overview

The 54672530 air filter element is a genuine Ingersoll Rand intake filter designed for N55 and N75 screw air compressors. Its high-efficiency synthetic/fiberglass media blocks dust and particulate matter from entering the screw airend, protecting rotors, bearings, and oil seals to extend 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 several Atlas Copco part numbers.

• Relative humidity: ≤95% RH, non-condensing
• Collapse pressure: ≥4.0 kPa
• Features: low resistance, high dust holding capacity, suitable for continuous industrial duty

Service Life & Storage

• Service life: approx. 4,000 hours (8–12 months) under standard conditions; 2,000–3,000 hours in high-dust environments
• Shelf life: 36 months in original sealed packaging, dry, ambient temperature

Standards

• ISO 5011 — Inlet air cleaning equipment for internal combustion engines and compressors
• ISO 16890 / EN 779 — Air filters for general ventilation
• GB/T 14295 — Air filters
• GB/T 6165 — Test methods for air filters

Maintenance & Installation

Replacement Interval

• 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 media turns black, shows heavy dust build-up, or differential pressure reaches 900 Pa

Installation Steps

1. Shut down and isolate: switch off main power, apply lockout/tagout (LOTO), confirm the compressor has fully stopped.
2. Open the filter housing: loosen the cover bolts or clips and remove the cover.
3. Remove the old element: pull out the old 54672530 element and check for any gasket residue in the housing groove.
4. Clean the housing: wipe the inner wall and sealing surface with a clean cloth.
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: place it vertically into the housing center, ensuring both seals seat correctly without misalignment.
7. Refit the cover: reinstall the cover and tighten bolts or clips evenly.
8. Start-up check: start the compressor and listen for any air leaks at the filter housing.
