IV. Standard Maintenance and Installation Steps
Replacement Interval
- Standard operating conditions: every 8000 hours or 12 months (whichever comes first)
- High-dust conditions (mining, building materials, foundry, etc.): every 4000~6000 hours
- Replace immediately when the differential pressure alarm is triggered (≥750 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.
- Open the intake filter housing: Loosen the clips or bolts of the filter housing and remove the upper cover.
- Remove the old filter element: Pull out the old ATS11057 filter element vertically upward, and check whether the sealing 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, no oil contamination, and no foreign matter.
- Inspect the new filter element: Verify the new part number ATS11057, and check whether the filter media is damaged and whether the sealing ring is deformed.
- Install the new filter element: Place the new filter element vertically into the center of the housing, ensuring that the sealing ring fits evenly against the sealing surface without deviation.
- Reinstall the housing: Refit the upper cover, and evenly tighten the bolts or fasten the clips to ensure a tight seal with no gaps.
- Start up and check for leaks: Start the machine and run it, 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 120~180 Pa).
V. Frequently Asked Questions
Q1: Which Ingersoll Rand air compressors is ATS11057 compatible with?
A: ATS11057 is designed specifically for Ingersoll Rand ATS series oil-free centrifugal air compressors and is compatible with units in the 110kW power range. If you are unsure whether it applies to your model, please provide the air compressor serial number, and we will match it precisely for you.
Q2: What is the difference between ATS11057 and the air filter element of an ordinary screw air compressor?
A: Centrifugal air compressors have much higher requirements for intake air cleanliness than screw compressors. ATS11057 uses H11-grade micro-glass fiber filter media (99.97%@2.0μm), while ordinary screw compressor air filter elements are only F5 grade (98%@5μm). Using an ordinary air filter element will cause dust accumulation on the impeller of the centrifugal air compressor, damage to dynamic balance, and may even cause impeller wear and scrapping.
Q3: How can I determine whether 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 750 Pa; ② the replacement interval of 8000 hours or 12 months is reached; ③ visual inspection reveals damaged filter media or an aged and deformed sealing ring.
Q4: Is ATS11057 a genuine original part?
A: ATS11057 is a genuine Ingersoll Rand original accessory, manufactured strictly in accordance with Ingersoll Rand's globally unified technical standards, and is compatible with Ingersoll Rand original intake filter housings.
Q5: What is the delivery lead time for ATS11057?
A: ATS11057 is a long-lead-time ordered part, with a standard delivery lead time of approximately 110 days. It is recommended to plan procurement in advance to avoid affecting the normal operation of the unit.
