Product Overview
The ATS11057 air filter element is a genuine Ingersoll Rand replacement part engineered 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 from entering the core compression chamber, protecting precision impellers and diffusers from wear while supporting ISO 8573-1 Class 0 oil-free air quality.
As an OEM part under the Ingersoll Rand CC (Centrifugal Compressor) product line, group P266, 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 minimize downtime.

| Filter Class | H11 (sub-high efficiency, per EN 1822 / ISO 29463) |
| Dust Holding Capacity | Approx. 2.2 kg (at rated flow, final resistance) |
| Filtration Ratio β | β₂.₀ ≥ 3333 |
The ATS11057 uses micro-fiberglass media with 99.97% efficiency for particles 2.0 μm and above — far exceeding standard screw compressor air filters (F5 class, 98% @ 5 μm) and meeting the stringent intake cleanliness requirements of centrifugal compressors.
2. 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) |
| Operating Differential Range | 180–600 Pa |
| Alarm / Final Resistance | Alarm: 750 Pa; Final: 1000 Pa (must replace) |
| Pressure Drop vs. Energy | Each 100 Pa increase in intake pressure loss raises compressor shaft power by approx. 0.35% |
Ingersoll Rand data indicates this intake 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.
3. Dimensions and Installation
| Parameter | Value |
|---|---|
| Dimensions | Approx. φ350 × φ180 × 320 mm (OD × ID × height) |

| Sealing | Polyurethane (PU) foam gasket, integrated into end frame for seamless zero-leak fit |
4. Material Construction
| Parameter | Value |
|---|---|
| Media | Micro-fiberglass |
| Media Weight | Approx. 120–150 g/m² |
| Inner/Outer Support | Inner galvanized metal support mesh + outer protective mesh, prevents media collapse |
| End Caps | Polystyrene frame, lightweight, corrosion-resistant, incinerable |
| Seal | Polyurethane (PU) one-piece foam gasket, high elasticity, seamless fit |
| Adhesive | Polyurethane adhesive bonds end caps to media, heat-resistant, no debonding |
5. Operating Tolerance

| Relative Humidity | ≤95% RH, no condensation |
| Collapse Pressure Resistance | Overall ≥ 3.0 kPa differential |
| 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 capacity)
- ISO 16889: Hydraulic fluid power filters — determination of filtration ratio β
- 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
Replacement Intervals
- 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 compressor main power, apply lockout/tagout (LOTO), confirm complete stop.
- Open intake filter housing: Release housing latches or bolts and remove the cover.
- Remove old element: Pull the old ATS11057 element vertically upward; check for any seal remaining in the housing groove.
- Clean housing interior: Wipe the housing 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 seal for deformation.
- Install new element: Place vertically into the housing center, ensuring the seal seats evenly on the sealing surface without skewing.
- Reassemble housing: Refit cover, evenly tighten bolts or secure latches to ensure a gap-free seal.
- Start and leak-check: Run the machine, listen for air leaks at the intake filter, and verify differential pressure gauge returns to normal (initial 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 class. If unsure, provide your 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 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 in three cases: ① operating differential reaches the alarm value of 750 Pa; ② the 8,000-hour or 12-month interval is reached; ③ visual inspection reveals media damage or seal aging/deformation.
Q4: Is the ATS11057 a genuine OEM part?
A: Yes, the ATS11057 is a genuine Ingersoll Rand part manufactured to Ingersoll Rand global technical standards, 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 item with a standard lead time of approximately 110 days. Plan procurement in advance to avoid impact on compressor operation.
