Product Overview
The ATS11057 air filter element is a genuine Ingersoll Rand inlet filter designed specifically for ATS series oil-free centrifugal compressors. Using micro-fiberglass media with 99.97% filtration efficiency at 2.0 μm, it blocks dust and particulate matter from entering the core compression chamber, protecting precision impellers and diffusers from wear while helping maintain ISO 8573-1 Class 0 oil-free air quality.
As an original part under the Ingersoll Rand CC (Centrifugal Compressor) product line, P266 product group, the ATS11057 is manufactured to Ingersoll Rand global technical standards. It delivers three core advantages — low initial pressure drop, high dust holding capacity, and long service life — helping operators reduce energy consumption and maintenance downtime.

The ATS11057 uses micro-fiberglass media achieving 99.97% efficiency for particles ≥2.0 μm — far exceeding standard screw compressor air filters (F5 class, 98% @ 5 μm) and meeting the stringent inlet cleanliness requirements of centrifugal compressors.
Flow and Pressure Drop
| Parameter | Value |
|---|---|
| Rated Air Flow | Approx. 17–32 Nm³/min (for 110 kW class centrifugal units) |
| Initial Pressure Drop | Approx. 120–180 Pa (clean, at rated flow) |

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 — determination of filtration 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 Interval
- Standard 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 differential pressure alarm triggers (≥750 Pa)
Installation Steps
- Shut down and lock out: Turn off main compressor power, apply lockout/tagout (LOTO), confirm the unit is fully stopped.
- Open inlet filter housing: Release housing clamps or bolts and remove the cover.
- Remove old element: Pull the old ATS11057 element vertically upward; check whether the gasket remains in the housing groove.
- Clean housing interior: Wipe the inner wall and sealing surface with a clean cloth — no dust, oil, or foreign matter.
- Inspect new element: Verify 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 skewing.
- Reassemble housing: Refit the cover and tighten bolts or clamps evenly for a gap-free seal.
- Start up and leak-check: Run the compressor, listen for air leaks at the inlet filter, and confirm the differential pressure gauge reads normal (initial drop should be 120–180 Pa).
FAQ
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 class. If unsure, provide your compressor serial number and we will confirm the exact match.
Q2: How is the ATS11057 different from a standard screw compressor air filter?
A: Centrifugal compressors require much higher inlet cleanliness than screw compressors. The ATS11057 uses H11 micro-fiberglass media (99.97% @ 2.0 μm), while standard screw compressor filters are only F5 class (98% @ 5 μm). Using a standard filter can cause impeller fouling, imbalance, and even 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 750 Pa alarm value; ② 8000 hours or 12 months have elapsed; ③ visual inspection shows media damage or gasket aging/deformation.
Q4: Is the ATS11057 a genuine original part?
A: The ATS11057 is a genuine Ingersoll Rand original part manufactured to Ingersoll Rand global technical standards, designed to fit original Ingersoll Rand inlet 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. Plan procurement in advance to avoid affecting compressor operation.
