Product Overview
ATS11057 is a genuine Ingersoll Rand intake air filter element built for ATS series oil-free centrifugal compressors. The element uses micro-fiberglass media rated at 99.97% filtration efficiency at 2.0 μm, blocking dust and particulate from reaching the compression chamber, protecting the impeller and diffuser from erosion and helping maintain ISO 8573-1 Class 0 oil-free air quality.
As an OEM part within the Ingersoll Rand CC (Centrifugal Compressor) product line, P266 product group, ATS11057 is manufactured to Ingersoll Rand global technical standards. Its three core advantages are low initial pressure drop, high dust holding capacity and long service life, which together reduce compressor energy consumption and maintenance downtime.

Technical Data
Filtration Performance
| Parameter | Value |
|---|---|
| Filtration Rating | 2.0 μm |
| Filtration 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, final resistance) |
| Beta Ratio β | β₂.₀ ≥ 3333 |
The micro-fiberglass media captures 99.97% of particles at 2.0 μm and above, well above the F5 class (98% @ 5 μm) typical of standard screw compressor intake filters, meeting the stricter intake cleanliness requirements of centrifugal compressors.
Flow and Pressure Drop
| Parameter | Value |
|---|---|
| Rated Air Flow | Approx. 17–32 Nm³/min (110 kW class centrifugal unit) |
| Initial Pressure Drop | Approx. 120–180 Pa (clean, rated flow) |
| Operating Differential Range | 180–600 Pa |
| Alarm / Final Resistance | Alarm: 750 Pa; final resistance: 1000 Pa (replace immediately) |
| Pressure Drop vs. Energy | Each 100 Pa increase in intake loss adds approx. 0.35% to compressor shaft power |
Ingersoll Rand data for this intake filter series indicates a clean pressure drop approximately 40% lower than comparable alternatives and dust holding capacity approximately 89% higher, which lowers compressor running energy and extends replacement intervals.
Dimensions and Installation
| Parameter | Value |
|---|---|
| Dimensions | Approx. φ350 × φ180 × 320 mm (OD × ID × height) |
| Effective Filter Area | Approx. 8–10 m² (pleated cartridge, unfolded) |
| Pleats / Pleat Spacing | Approx. 150–180 pleats, spacing approx. 6–8 mm |
| Mounting Interface | Flange / end-cap slot type, mates with intake filter housing |
| Sealing | Polyurethane (PU) foam gasket integrated into the media end frame for gap-free, leak-free seating |
Construction Materials
| Parameter | Value |
|---|---|
| Media | Micro-fiberglass |
| Media Weight | Approx. 120–150 g/m² |
| Support Structure | Inner galvanized metal support mesh plus outer protective mesh to prevent media collapse |
| End Caps | Polystyrene frame — lightweight, corrosion-resistant, incinerable |
| Gasket | One-piece polyurethane (PU) foam gasket, high elasticity, seamless fit |
| Bonding | Polyurethane adhesive bonds end caps to media; heat-resistant, no de-bonding |
Operating Conditions
| Parameter | Value |
|---|---|

| Relative Humidity | ≤95% RH, no condensation |
| Collapse Pressure Resistance | ≥ 3.0 kPa differential |
| Features | Low initial pressure drop, high dust holding capacity, long replacement interval, zero-leak seal |
Service Life and Storage
| Parameter | Value |
|---|---|
| Service Life | Approx. 8,000 hours (about 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 |
Standards
- ISO 5011 — intake filter performance testing (efficiency and dust capacity) for engines and compressors
- ISO 16889 — determination of beta ratio for hydraulic filters
- ISO 29463 / EN 1822 — classification and testing of high-efficiency air filters (HEPA and ULPA)
- GB/T 14295 — air filters
- GB/T 6165 — air filter performance test methods (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, foundries): 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 the compressor 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 and check whether the gasket remains in the housing groove.
- Clean the housing interior: wipe the inner wall and sealing face with a clean cloth; ensure no dust, oil or foreign matter remains.
- Inspect the new element: verify part number ATS11057 and check the media for damage and the gasket for deformation.
- Install the new element: place it vertically in the housing center so the gasket seats evenly on the sealing face without tilting.
- Refit the housing: reinstall 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 intake filter, and confirm the differential pressure gauge returns to normal (initial pressure drop should be 120–180 Pa).
FAQ
Q1: Which Ingersoll Rand compressors does ATS11057 fit?
A: 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 confirm exact fitment.
Q2: How is ATS11057 different from a standard screw compressor intake filter?
A: Centrifugal compressors require much cleaner intake air than screw compressors. ATS11057 uses H11 micro-fiberglass media (99.97% @ 2.0 μm), while standard screw compressor intake filters are typically F5 class (98% @ 5 μm). Using a standard filter can cause dust buildup on the impeller, disturb dynamic balance, and even lead to impeller wear and scrapping.
Q3: How do I know when to replace the intake filter element?
A: Replace in any of three cases: (1) operating differential pressure reaches the 750 Pa alarm value; (2) the 8,000-hour or 12-month interval is reached; (3) visual inspection shows damaged media or a hardened, deformed gasket.
Q4: Is ATS11057 a genuine OEM part?
A: ATS11057 is a genuine Ingersoll Rand OEM part, produced to Ingersoll Rand global technical standards and designed for 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. Plan procurement in advance to avoid unplanned downtime.
