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

54672530 is a genuine Ingersoll Rand intake air filter element engineered for N55 and N75 rotary screw air compressors. The pleated cylindrical cartridge uses high-efficiency synthetic fiberglass media to block dust and particulate matter before it reaches the screw airend — protecting rotors, bearings, and shaft seals from abrasive wear and extending compressor service life.

The 54672530 measures approximately 247 mm outside diameter by 365 mm overall height and features a red polyurethane (PU) end-cap seal. It is cross-compatible with several Atlas Copco part numbers and carries the aftermarket reference HiFi Filter SA17281.

• Relative humidity: ≤95% RH, no condensation
• Collapse pressure resistance: ≥4.0 kPa
• 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 sealed original packaging, dry ambient conditions

Standards

• 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

Installation & Maintenance

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 the media appears blackened or heavily loaded, or when differential pressure reaches 900 Pa

Installation Steps

1. Shut down and isolate: switch off main power, apply lockout/tagout (LOTO), and confirm the unit has fully stopped.
2. Open the filter housing: release the cover bolts or clamps and remove the cover.
3. Remove the old element: pull out the used 54672530 element and check whether the old gasket 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: seat it vertically in the center of the housing with both seals fully engaged — do not tilt.
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.

Frequently Asked Questions

Q1: Is 54672530 a genuine OEM part?
A: Yes — 54672530 is a genuine Ingersoll Rand part with yellow high-efficiency media and a red polyurethane end-cap seal, designed for N55/N75 rotary screw compressors.
