III. Standard Maintenance and Installation Steps
Replacement Interval
- Standard operating conditions: every 4000~6000 hours or 8~10 months (whichever comes first)
- High-dust conditions (mining, building materials, cement, steel, etc.): every 3000 hours
- Replace immediately when the differential pressure alarm is triggered (≥700 Pa)
Installation Steps
- Shut down and disconnect power: Turn off the main power supply of the air compressor, apply lockout/tagout (LOTO), and confirm that the unit has completely stopped running and has been depressurized.
- Open the intake filter housing: Loosen the latches or bolts of the large intake filter housing, and remove the upper cover or access door.
- Remove the old filter element: Pull the old ATN72018 filter element straight up and out, and check whether the seal ring remains in the housing groove.
- Clean the inside of the housing: Wipe the inner wall and sealing surface of the filter housing with a clean cloth to ensure there is no dust, oil, or foreign matter.
- Inspect the new filter element: Verify the new part number ATN72018, and check the filter media for damage, the pleats for deformation, and the seal ring for aging.
- Install the new filter element: Place the new filter element vertically into the center of the housing, ensuring that the seal ring fits evenly against the sealing surface without tilting or twisting.
- Reinstall the housing: Refit the upper cover or access door, and evenly tighten the bolts or fasten the latches to ensure a tight seal with no gaps.
- Start up and check for leaks: Start the machine and check for any air leakage noise at the intake filter, and observe whether the differential pressure gauge reading returns to normal (the initial pressure drop should be in the range of 250~350 Pa).
IV. Frequently Asked Questions
Q1: Which Ingersoll Rand air compressors is ATN72018 compatible with?
A: ATN72018 is designed specifically for Ingersoll Rand ATN series 720kW high-power oil-free centrifugal air compressors. If you are unsure whether it is suitable for your model, please provide the air compressor serial number, and we will match it precisely for you.
Q2: What is the difference between ATN72018 and the air filter element of an ordinary screw air compressor?
A: Centrifugal air compressors have much higher requirements for intake air cleanliness and air volume than screw compressors. ATN72018 uses high-efficiency micro-glass fiber filter media (99.9%@3.0μm), with a single unit handling 50~80 Nm³/min, whereas ordinary screw compressor air filter elements are only F5 grade (98%@5μm), with an air handling capacity of only a few to several dozen Nm³/min. Using ordinary air filter elements will cause dust accumulation on the impeller of large centrifugal air compressors, disrupt dynamic balance, and even cause expensive impeller wear and scrapping.
Q3: How can I tell when the air filter element needs to be replaced?
A: Replacement is required in three cases: ① the operating differential pressure reaches the alarm value of 700 Pa; ② the replacement interval of 4000~6000 hours or 8~10 months is reached; ③ visual inspection reveals damage to the filter media or aging and deformation of the seal ring.
Q4: Is ATN72018 a genuine original part?
A: ATN72018 is a genuine Ingersoll Rand original accessory, manufactured in strict accordance with Ingersoll Rand's globally unified technical standards, and is compatible with Ingersoll Rand original intake filter housings.
Q5: Is one filter element of ATN72018 enough?
A: The intake filter of a 720kW large centrifugal air compressor is usually designed with multiple filter elements in parallel. The exact number required depends on the specifications of the intake filter assembly; please provide the serial number to confirm the configuration quantity.
