Product Overview
The ATS11057 air filter element is a genuine Ingersoll Rand intake filter element engineered specifically for ATS series oil-free centrifugal compressors. Built with micro-fiberglass media rated at 99.97% efficiency @ 2.0 μm, it blocks dust and particulate matter from entering the core compression chamber, protecting precision impellers and diffusers from erosion and helping maintain ISO 8573-1 Class 0 oil-free air quality.
As an original part in 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 cut energy consumption and reduce unplanned downtime.

Filtration Performance
| Parameter | Value |
|---|---|
| Filtration Rating | 2.0 μm |
| 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 |
Micro-fiberglass media captures 99.97% of particles 2.0 μm and larger — well above standard screw compressor intake filters (F5 class, 98% @ 5 μm) — meeting the stringent intake cleanliness demands of centrifugal compressors.
Flow and Pressure Drop
| Parameter | Value |
|---|---|
| Rated Air Flow | Approx. 17–32 Nm³/min (110 kW class centrifugal units) |
| Initial Pressure Drop | Approx. 120–180 Pa (clean, rated flow) |
| Operating Differential Range | 180–600 Pa |
| Alarm / Terminal Resistance | Alarm: 750 Pa; terminal: 1000 Pa (replace immediately) |
| Pressure Drop vs. Energy | Every 100 Pa rise in intake loss adds approx. 0.35% to compressor shaft power |
Ingersoll Rand data indicates this intake filter series runs a clean pressure drop roughly 40% lower and dust-holding capacity about 89% higher than comparable alternatives, reducing energy use and extending replacement intervals.

Applicable Standards
- ISO 5011 — Inlet air cleaning equipment for internal combustion engines and compressors (efficiency and dust capacity)
- ISO 16889 — Hydraulic fluid power filters, determination of beta ratio
- ISO 29463 / EN 1822 — High-efficiency air filters (HEPA and ULPA) classification and testing
- GB/T 14295 — Air filters
- GB/T 6165 — Test methods for air filter performance (efficiency and resistance)
Maintenance and 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 the differential pressure alarm triggers (≥750 Pa)
Installation Steps
- Shut down and isolate power — switch off main power, apply lockout/tagout (LOTO) and confirm the unit has fully stopped.
- Open the intake filter housing — release the housing clamps or bolts and remove the cover.
- Remove the old element — pull the old ATS11057 element straight up; check whether the gasket remains in the housing groove.
- Clean the housing interior — wipe the inner walls and sealing face with a clean cloth; ensure no dust, oil or debris remains.
- Inspect the new element — verify part number ATS11057 and check media for damage and gasket for deformation.
- Install the new element — seat it vertically in the housing center, ensuring the gasket contacts the sealing face evenly with no tilt.
- Refit the housing — replace the cover and tighten bolts or clamps evenly for a gap-free seal.
- Start up and leak-check — run the unit, listen for air leaks at the intake filter and confirm the differential pressure gauge reads normal (initial drop should be 120–180 Pa).
Frequently Asked Questions
Q1: Which Ingersoll Rand compressors does 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 about your model, provide the compressor serial number and we will match it precisely.
Q2: How is ATS11057 different from a standard screw compressor intake filter?
A: Centrifugal compressors demand far higher intake cleanliness than screw machines. ATS11057 uses H11 micro-fiberglass media (99.97% @ 2.0 μm), while standard screw intake filters are only F5 class (98% @ 5 μm). Using the wrong filter allows dust build-up on centrifugal impellers, upsets dynamic balance and can lead to impeller wear or scrapping.
Q3: How do I know when to replace the element?
A: Three triggers: (1) operating differential pressure reaches the 750 Pa alarm value; (2) the 8,000-hour or 12-month interval is reached; (3) visual inspection reveals damaged media or an aged, deformed gasket.
Q4: Is ATS11057 a genuine original part?
A: Yes — ATS11057 is a genuine Ingersoll Rand original part manufactured to Ingersoll Rand global technical standards and designed to fit the original intake filter housing.
Q5: What is the lead time for ATS11057?
A: ATS11057 is a long-lead order part with a standard lead time of approximately 110 days. We recommend planning procurement in advance to avoid downtime.
