Ingersoll Rand 54672530 Air Filter Element for N55/N75 Screw Compressors

Product Overview

The Ingersoll Rand 54672530 air filter element is a genuine OEM intake filter for N55 and N75 screw air compressors. Its pleated synthetic fiber/glass fiber media captures dust and airborne particles before they reach the airend, helping protect rotors, bearings, and shaft seals from abrasive wear.

This large cylindrical element measures approximately 247 mm outside diameter by 365 mm overall height, with a red polyurethane end-cap gasket. It cross-references HiFi Filter SA17281 and is compatible with several Atlas Copco part numbers (see cross-reference table below).

Technical Specifications

• 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 & 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 filter performance

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 is blackened, heavily loaded, or pressure differential reaches 900 Pa

Installation Steps

1. Shut down and isolate: switch off main power, apply lockout/tagout (LOTO), confirm the machine has fully stopped.
2. Open the filter housing: release the retaining bolts or clamps and remove the cover.
3. Remove the old element: pull out the old 54672530 element; check for any gasket residue in the housing groove.
4. Clean the housing: wipe the inner walls and sealing surfaces 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 clamps evenly.
8. Start-up check: start the compressor and listen for air leaks around the filter housing.
