Product Overview
ATS11057 is a genuine Ingersoll Rand intake air filter element engineered specifically for the ATS series oil-free centrifugal compressors. Built with micro-fiberglass filtration media, it delivers a filtration efficiency of 99.97% @ 2.0 μm, effectively blocking dust and particulate matter from entering the core compression chamber. This protects the precision impeller and diffuser from wear and supports ISO 8573-1 Class 0 oil-free air quality.
As an original part in the Ingersoll Rand CC (Centrifugal Compressor) product line, P266 product group, the ATS11057 is manufactured to Ingersoll Rand global technical standards. Its three core advantages — low initial pressure drop, high dust holding capacity, and long service life — help operators reduce energy consumption and downtime.

Standard Maintenance and Installation
Replacement Interval
- Standard conditions: every 8,000 hours or 12 months, whichever comes first
- High-dust conditions (mining, building materials, foundry, etc.): every 4,000–6,000 hours
- Replace immediately when differential pressure alarm triggers (≥750 Pa)
Installation Steps
- Shut down and lock out: Turn off main power, apply lockout/tagout (LOTO), confirm the unit has fully stopped.
- Open the intake filter housing: Release housing clamps or bolts and remove the top cover.
- Remove old element: Pull out the old ATS11057 element vertically upward. Check whether the gasket remains in the housing groove.
- Clean housing interior: Wipe the inner walls and sealing surfaces with a clean cloth; ensure no dust, oil, or foreign matter.
- Inspect new element: Verify the new part number ATS11057; check media for damage and gasket for deformation.
- Install new element: Place vertically into the housing center, ensuring the gasket seats evenly on the sealing surface without tilting.
- Reassemble housing: Replace the top cover, tighten bolts or clamps evenly to ensure a gap-free seal.
- Start up and leak-check: Run the compressor, listen for air leaks at the intake filter, and check the differential pressure gauge (initial pressure drop should be 120–180 Pa).
Frequently Asked Questions
Q1: Which Ingersoll Rand compressors does the ATS11057 fit?
A: The ATS11057 is designed for Ingersoll Rand ATS series oil-free centrifugal compressors, 110 kW power class. If you are unsure about your model, provide the compressor serial number and we will match the exact part.
Q2: How is the ATS11057 different from a standard screw compressor air filter?
A: Centrifugal compressors require much higher intake cleanliness than screw compressors. The ATS11057 uses H11 micro-fiberglass media (99.97% @ 2.0 μm), while standard screw compressor filters are only F5 grade (98% @ 5 μm). Using a standard filter can cause dust buildup on the impeller, disrupt dynamic balance, and even lead to impeller wear and scrapping.
Q3: How do I know when to replace the air filter element?
A: Replace when: ① operating differential pressure reaches the alarm value of 750 Pa; ② the replacement interval of 8,000 hours or 12 months is reached; ③ visual inspection reveals media damage or gasket aging/deformation.
Q4: Is the ATS11057 a genuine original part?
A: Yes, the ATS11057 is a genuine Ingersoll Rand original part, manufactured to Ingersoll Rand global technical standards and compatible with Ingersoll Rand original intake filter housings.
Q5: What is the lead time for the ATS11057?
A: The ATS11057 is a long lead time item with a standard delivery of approximately 110 days. We recommend planning your purchase in advance to avoid impacting compressor operation.
