4. Maintenance and installation procedure
Replacement cycle
- Standard conditions: every 6,000–8,000 hours or 8–12 months (whichever comes first)
- High-dust environments (mines, construction materials, cement, steel...): every 3,000–4,000 hours
- Replace immediately when a differential pressure warning occurs (≥650 Pa)
Installation steps
- Stop the machine and disconnect power: Turn off the compressor main power, hang a lockout tag (LOTO), confirm the unit has fully stopped and depressurize.
- Open the intake air filter housing: Loosen the housing latches or bolts, remove the top cover or inspection door.
- Remove the old filter element: Pull the old ATN18504 element straight up, check whether any gasket remains in the housing groove.
- Clean the inside of the housing: Use a clean cloth to wipe the inner surface and sealing surface of the filter housing, ensuring there is no dust, oil, or foreign matter.
- Inspect the new filter element: Verify the ATN18504 code, check that the filter material is not torn, the pleats are not deformed, and the gasket is not aged.
- Install the new filter element: Place the new element straight into the central position of the housing, ensuring the gasket contacts the sealing surface evenly, without misalignment or twisting.
- Close the housing: Reinstall the top cover, tighten the bolts or latches evenly by hand, ensuring a tight seal with no gaps.
- Start up and check for leaks: Run the machine, check for air leakage sounds at the filter, and observe whether the differential pressure gauge returns to normal (initial loss in the range of 220–300 Pa).
5. Frequently Asked Questions
Q1: Which Ingersoll Rand compressors is ATN18504 compatible with?
A: ATN18504 is specifically designed for Ingersoll Rand ATN series 185kW oil-free centrifugal compressors. If you are unsure, please provide the compressor serial number so we can look it up accurately.
Q2: How is ATN18504 different from a standard screw compressor filter element?
A: Centrifugal compressors require much higher intake air cleanliness than screw compressors. ATN18504 uses glass microfiber material (99.5% @ 3.0μm), while screw compressor filter elements only reach F5 grade (98% @ 5μm). Using a standard filter element will cause dust buildup on the turbine blades, dynamic imbalance, and even costly turbine blade damage.
Q3: How do I know when the air filter element needs to be replaced?
A: There are three cases that require replacement: ① The operating differential pressure reaches the 650 Pa warning threshold; ② The 6,000–8,000 hour or 8–12 month cycle is reached; ③ Visual inspection reveals torn filter material or deformed, aged gaskets.
Q4: Is ATN18504 a genuine part?
A: ATN18504 is a genuine Ingersoll Rand spare part, manufactured to Ingersoll Rand's global technical standards, and compatible with the original intake air filter housing.
Q5: Is one ATN18504 element enough?
A: The intake air filter of a centrifugal compressor may use one or multiple elements. The specific quantity depends on the intake air filter assembly; please provide the serial number for confirmation.
