Product Overview
The ATS11057 air filter element is a genuine Ingersoll Rand intake filter element engineered specifically for ATS series oil-free centrifugal compressors. Manufactured with micro-fiberglass media, it achieves 99.97% filtration efficiency at 2.0 μm, effectively blocking dust and particulate matter from entering the compressor's core compression chamber. This protects precision impellers and diffusers from wear and helps maintain ISO 8573-1 Class 0 oil-free air quality.
As an original accessory in the Ingersoll Rand CC (Centrifugal Compressor) product line, P266 product group, the ATS11057 is produced to Ingersoll Rand's global technical standards. Its three core advantages — low initial pressure drop, high dust holding capacity, and extended service life — help operators reduce energy consumption and minimize downtime for maintenance.

Standard Maintenance and Installation
Replacement Intervals
- Standard conditions: every 8,000 hours or 12 months, whichever comes first
- High-dust conditions (mining, building materials, foundries): 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 to the compressor, apply lockout/tagout (LOTO), and confirm the unit has fully stopped.
- Open the intake filter housing: Release the housing latches or bolts and remove the cover.
- Remove the old element: Pull the old ATS11057 element straight up and out; check whether the gasket remains in the housing groove.
- Clean the housing interior: Wipe the housing inner wall and sealing surface with a clean cloth; ensure no dust, oil, or foreign matter remains.
- Inspect the new element: Verify the part number ATS11057 and check the media for damage and the gasket for deformation.
- Install the new element: Place it vertically into the center of the housing, ensuring the gasket seats evenly on the sealing surface without tilting.
- Reassemble the housing: Refit the cover and tighten bolts or latches evenly to ensure a gap-free seal.
- Start up and leak-check: Run the compressor, listen for air leaks at the intake filter, and confirm the differential pressure gauge reads normally (initial drop should be 120–180 Pa).
Frequently Asked Questions
Q1: Which Ingersoll Rand compressors does the ATS11057 fit?
A: The ATS11057 is designed specifically for Ingersoll Rand ATS series oil-free centrifugal compressors in the 110 kW power range. If you are unsure whether it fits your model, provide the compressor serial number and we will match it precisely.
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 grade micro-fiberglass media (99.97% @ 2.0 μm), whereas standard screw compressor filters are only F5 grade (98% @ 5 μm). Using a standard filter can cause dust buildup on centrifugal impellers, 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 in three cases: (1) operating differential pressure reaches the alarm value of 750 Pa; (2) the 8,000-hour or 12-month replacement interval is reached; (3) visual inspection reveals media damage or a hardened, deformed gasket.
Q4: Is the ATS11057 a genuine original part?
A: The ATS11057 is a genuine Ingersoll Rand original accessory, manufactured to Ingersoll Rand's global technical standards, and fits the original Ingersoll Rand intake filter housing.
Q5: What is the lead time for the ATS11057?
A: The ATS11057 is a long lead-time order item with a standard lead time of approximately 110 days. We recommend planning purchases in advance to avoid affecting compressor operation.
