Product Overview
ATS11057 is a genuine Ingersoll Rand air filter element engineered specifically for the ATS series oil-free centrifugal compressors. Built with H11-grade micro-fiberglass media, it delivers 99.97% filtration efficiency at 2.0 μm, blocking dust and particulate matter from entering the core compression chamber, protecting precision impellers and diffusers from erosion, and supporting ISO 8573-1 Class 0 oil-free air quality.
As an original accessory from 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 minimize unplanned downtime.

Technical Parameters
1. Filtration Performance (Core Metrics)

| Filtration Efficiency | 99.97% @ 2.0 μm |
| Filter Class | H11 (sub-HEPA, per EN 1822 / ISO 29463) |
| Dust Holding Capacity | Approx. 2.2 kg (at rated flow, terminal resistance) |
| Beta Ratio β | β₂.₀ ≥ 3333 |
The ATS11057 uses micro-fiberglass media with 99.97% efficiency for particles 2.0 μm and above — significantly higher than standard screw compressor air filters (F5 class, 98% @ 5 μm). This meets the stringent intake air cleanliness requirements of centrifugal compressors.
2. Flow and Resistance Parameters
| Parameter | Value |
|---|---|
| Rated Air Flow | Approx. 17–32 Nm³/min (for 110 kW class centrifugal units) |
| Initial Pressure Drop | Approx. 120–180 Pa (clean condition, rated flow) |
| Operating Differential Pressure Range | 180–600 Pa |
| Alarm / Terminal Resistance | Alarm: 750 Pa; Terminal: 1000 Pa (must replace) |
| Pressure Drop vs. Energy | Every 100 Pa increase in intake pressure loss raises compressor shaft power by approx. 0.35% |
Ingersoll Rand data indicates this intake filter series offers approximately 40% lower clean pressure drop and 89% higher dust holding capacity than comparable competitor filters, reducing compressor energy consumption and extending replacement intervals.
3. Dimensions and Installation

| Sealing | Polyurethane (PU) foam gasket integrated into media end frame, seamless zero-leak fit |
4. Material Construction
| Parameter | Value |
|---|---|
| Media | Micro-fiberglass |
| Media Weight | Approx. 120–150 g/m² |

| Relative Humidity | ≤95% RH, no condensation |
| Collapse Pressure Resistance | Overall collapse differential pressure ≥ 3.0 kPa |
| Special Features | Low initial pressure drop, high dust holding capacity, long replacement interval, zero-leak seal |
6. Service Life and Maintenance
| Parameter | Value |
|---|---|
| Service Life | Approx. 8,000 hours (approx. 1 year) under standard conditions; 4,000–6,000 hours in high-dust environments |
| Shelf Life | 36 months in original sealed packaging, dry ambient temperature |
7. Applicable Standards
- ISO 5011: Inlet air cleaning equipment for internal combustion engines and compressors — performance testing (efficiency and dust holding capacity)
- ISO 16889: Hydraulic fluid power filters — multi-pass method for evaluating filtration performance (beta ratio)
- ISO 29463 / EN 1822: High-efficiency air filters (HEPA and ULPA) — classification and testing
- GB/T 14295: Air filters
- GB/T 6165: Methods for testing air filter performance (efficiency and resistance)
Standard Maintenance and Installation Steps
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 disconnect power: Turn off the main compressor power supply, 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 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.
- 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 the new element vertically into the housing center, ensuring the gasket seats evenly on the sealing surface without tilting.
- Refit the housing: Reinstall 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 check that the differential pressure gauge reads normally (initial pressure drop should be in the 120–180 Pa range).
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 class. 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 demand far higher intake air cleanliness than screw compressors. The ATS11057 uses H11-grade 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 centrifugal compressor 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 under any of three conditions: (1) operating differential pressure reaches the 750 Pa alarm value; (2) the 8,000-hour or 12-month replacement interval is reached; (3) visual inspection reveals media damage or gasket aging/deformation.
Q4: Is the ATS11057 a genuine original part?
A: The ATS11057 is a genuine Ingersoll Rand original accessory, manufactured to Ingersoll Rand global technical standards and designed to fit original Ingersoll Rand intake filter housings.
Q5: What is the lead time for the ATS11057?
A: The ATS11057 is a long lead-time order part with a standard lead time of approximately 110 days. We recommend planning procurement in advance to avoid impacting normal compressor operation.
