Product Overview
The ATS11057 air filter element is a genuine Ingersoll Rand intake filter designed 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 compression chamber. This protects precision impellers and diffusers from wear and supports 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 reduce energy consumption and minimize downtime.

| Dust Holding Capacity | Approx. 2.2 kg (at rated flow, terminal resistance) |
| Beta Ratio β | β₂.₀ ≥ 3333 |
The ATS11057 uses micro-fiberglass media achieving 99.97% efficiency for particles 2.0 μm and larger — far exceeding standard screw compressor air filters (F5 grade, 98% @ 5 μm). This meets the stringent intake cleanliness requirements of centrifugal compressors.
2. Flow and Resistance Parameters
| Parameter | Value |
|---|---|
| Rated Air Flow | Approx. 17–32 Nm³/min (for 110 kW class centrifugal units) |
| Initial Pressure Drop | Approx. 120–180 Pa (clean condition, rated flow) |
| Operating Differential Pressure | 180–600 Pa |
| Alarm / Terminal Resistance | Alarm: 750 Pa; Terminal: 1000 Pa (must replace) |
| Pressure Drop vs. Energy | Every 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 and dust holding capacity 89% higher than comparable alternatives, reducing energy consumption and extending replacement intervals.
3. Dimensions and Installation

| Sealing | Polyurethane (PU) foam gasket integrated into filter end frame, seamless zero-leak fit |
4. Material Construction
| Parameter | Value |
|---|---|
| Filter 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 Cap | Polystyrene frame, lightweight, corrosion-resistant, incinerable |
| Gasket | Polyurethane (PU) one-piece foam gasket, high elasticity, seamless fit |

| Relative Humidity | ≤95% RH, no condensation |
| Collapse Pressure Resistance | Overall collapse differential pressure ≥ 3.0 kPa |
| Special Features | Low initial pressure drop, high dust holding capacity, extended replacement interval, zero-leak seal |
6. Service Life and Maintenance
| Parameter | Value |
|---|---|
| Service Life | Approx. 8,000 hours under standard conditions (approx. 1 year); 4,000–6,000 hours in high-dust environments |
| Shelf Life | 36 months in original sealed packaging, ambient dry conditions |
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 — 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 performance of air filters (efficiency and resistance)
Standard Maintenance and Installation Steps
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 main power to the compressor, apply lockout/tagout (LOTO), confirm the unit has fully stopped.
- Open the intake filter housing: Release housing clamps or bolts and remove the cover.
- Remove old filter: Pull the old ATS11057 element straight up; check whether the gasket remains in the housing groove.
- Clean housing interior: Wipe the inner walls and sealing surfaces with a clean cloth — ensure no dust, oil, or foreign matter.
- Inspect new filter: Verify part number ATS11057; check media for damage and gasket for deformation.
- Install new filter: Place the new element vertically into the center of the housing, ensuring the gasket seats evenly against the sealing surface without skewing.
- Reassemble housing: Reinstall the cover and tighten bolts or clamps 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 class. If you are unsure about compatibility, provide the compressor serial number and we will match the correct part for you.
Q2: How is the ATS11057 different from a standard screw compressor air filter?
A: Centrifugal compressors require far 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 only F5 grade (98% @ 5 μm). Using a standard filter can cause dust buildup on centrifugal compressor impellers, disrupt dynamic balance, and even lead to impeller wear and scrapping.
Q3: How do I know when to replace the air filter element?
A: Replace in three situations: (1) operating differential pressure 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 gasket aging/deformation.
Q4: Is the ATS11057 a genuine OEM part?
A: The ATS11057 is a genuine Ingersoll Rand original part, manufactured to Ingersoll Rand global technical standards, and fits 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. We recommend planning purchases in advance to avoid impacting compressor operation.
