Product Overview
ATS11057 is a genuine Ingersoll Rand air filter element engineered for the ATS series of oil-free centrifugal compressors. Built with micro-fiberglass media, it delivers 99.97% filtration efficiency at 2.0 μm, blocking dust and particulate 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 original 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 long service life — help operators cut energy consumption and reduce unplanned downtime.

The ATS11057 uses micro-fiberglass media with 99.97% efficiency at 2.0 μm and above — far exceeding standard screw compressor air filters (F5 class, 98% @ 5 μm). It meets the strict inlet cleanliness demands of centrifugal compressors.
Flow & Pressure Drop
| Parameter | Value |
|---|---|
| Rated Air Flow | Approx. 17–32 Nm³/min (for 110 kW centrifugal units) |
| Initial Pressure Drop | Approx. 120–180 Pa (clean, rated flow) |
| Operating Differential Range | 180–600 Pa |
| Alarm / Final Resistance | Alarm: 750 Pa; Final: 1000 Pa (must replace) |
| Pressure Drop vs. Energy | Each 100 Pa rise in inlet loss increases compressor shaft power by approx. 0.35% |
According to Ingersoll Rand data, this inlet filter series has a clean pressure drop 40% lower than comparable competitors and 89% higher dust holding capacity, reducing energy consumption and extending replacement intervals.

Applicable Standards
- ISO 5011 — Inlet air filters for internal combustion engines and compressors: efficiency and dust capacity test
- ISO 16889 — Hydraulic filter elements: beta ratio determination
- ISO 29463 / EN 1822 — High-efficiency air filters (HEPA and ULPA): classification and testing
- GB/T 14295 — Air filters
- GB/T 6165 — Air filter performance test methods (efficiency and resistance)
Maintenance & 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 LOTO, confirm the unit has fully stopped.
- Open the inlet filter housing — Release the housing latches or bolts and remove the cover.
- Remove the old element — Pull the old ATS11057 straight up; check whether the gasket remains in the housing groove.
- Clean the housing interior — Wipe the inner wall and sealing surface with a clean cloth; ensure no dust, oil, or foreign matter.
- Inspect the new element — Verify part number ATS11057, check media for damage and gasket for deformation.
- Install the new element — Place vertically into the housing center; ensure the gasket seats evenly on the sealing surface without tilting.
- Refit the housing — Reinstall the cover and tighten bolts or latches 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 you are unsure, 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 inlet cleanliness than screw compressors. The ATS11057 uses H11 micro-fiberglass media (99.97% @ 2.0 μm), while standard screw compressor filters are typically 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: Three triggers: ① operating differential pressure reaches the 750 Pa alarm; ② 8,000 hours or 12 months of service; ③ visual inspection reveals media damage or a hardened/deformed gasket.
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 designed to fit the original inlet filter housing.
Q5: What is the lead time for the ATS11057?
A: The ATS11057 is a long-lead order item with a standard lead time of approximately 110 days. Plan procurement in advance to avoid affecting compressor operation.
