Product Overview
The ATS11057 air filter element is a genuine Ingersoll Rand replacement intake filter engineered specifically for ATS series oil-free centrifugal compressors. Built with H11-grade micro-fiberglass media, it delivers 99.97% filtration efficiency at 2.0 μm, effectively blocking dust and particulate matter from entering the core compression chamber. This protects the precision impeller and diffuser from erosion and helps maintain ISO 8573-1 Class 0 oil-free air quality.
As an OEM part under 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 extended service life—help operators reduce energy consumption and minimize unplanned downtime.

| Alarm / Terminal Resistance | Alarm: 750 Pa; Terminal: 1000 Pa (must replace) |
| Pressure Drop vs. Energy | Every 100 Pa increase in inlet pressure loss raises compressor shaft power by approx. 0.35% |
According to Ingersoll Rand data, this intake filter series offers 40% lower clean pressure drop and 89% higher dust holding capacity than comparable competitors, reducing energy consumption and extending replacement intervals.

Compliance Standards
- ISO 5011: Inlet air cleaning equipment for internal combustion engines and compressors—performance testing (efficiency and dust 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)
Maintenance and Installation
Replacement Schedule
- 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: Disconnect main power to the compressor, apply lockout/tagout (LOTO), and verify 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 for any gasket residue in the housing groove.
- Clean the housing interior: Wipe the inner walls and sealing surfaces with a clean cloth—no dust, oil, or debris.
- Inspect the new element: Verify the part number ATS11057, check the media for damage, and ensure the gasket is not deformed.
- Install the new element: Place it vertically into the housing center, ensuring the gasket seats evenly on the sealing surface without tilting.
- Reassemble 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 confirm the differential pressure gauge reads normal (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 in the 110 kW power range. If you are unsure about your model, provide the compressor serial number and we will match it precisely.
Q2: How does the ATS11057 differ from a standard rotary 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), while standard screw compressor filters are typically F5 grade (98% @ 5 μm). Using a standard filter can lead to dust buildup on the impeller, imbalance, and even impeller wear or 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 8,000-hour or 12-month interval is reached; or (3) visual inspection shows damaged media or an aged/deformed gasket.
Q4: Is the ATS11057 a genuine OEM part?
A: Yes, the ATS11057 is a genuine Ingersoll Rand replacement part, manufactured to Ingersoll Rand global technical standards and designed to fit the original 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 your procurement in advance to avoid operational disruptions.
