Ingersoll Rand ATS11057 Air Filter Element | ATS Centrifugal Compressor OEM Part

Product Overview

ATS11057 is a genuine Ingersoll Rand air filter element engineered for the ATS series oil-free centrifugal compressor intake. Manufactured with micro-fiberglass media rated at 99.97% @ 2.0 μm, it blocks dust and particulate from entering the compression chamber, protecting precision impellers and diffusers from erosion and supporting 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, ATS11057 is built 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.

Technical Data

Filtration Performance

• Filtration Rating: 2.0 μm
• Efficiency: 99.97% @ 2.0 μm
• Filter Class: H11 (sub-high efficiency, per EN 1822 / ISO 29463)
• Dust Holding Capacity: Approx. 2.2 kg (at rated flow, terminal resistance)
• Beta Ratio: β₂.₀ ≥ 3333

The micro-fiberglass media delivers 99.97% efficiency at 2.0 μm and above — well beyond standard rotary-screw compressor filters (F5 class, 98% @ 5 μm) — meeting the strict intake cleanliness demands of centrifugal compressors.

Flow and Pressure Drop

• Rated Air Flow: Approx. 17–32 Nm³/min (for 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 at 750 Pa; terminal resistance 1000 Pa (replacement mandatory)
• Pressure Drop vs. Energy: Every 100 Pa increase in intake loss raises compressor shaft power by approx. 0.35%

Ingersoll Rand data indicates this intake filter series runs at a clean pressure drop 40% lower and dust holding capacity 89% higher than comparable alternatives, reducing energy use and extending replacement intervals.

Dimensions and Installation

• Dimensions: Approx. φ350 × φ180 × 320 mm (OD × ID × height)
• Effective Filtration Area: Approx. 8–10 m² (pleated cartridge, unfolded)
• Pleats: Approx. 150–180 pleats, approx. 6–8 mm pitch
• Mounting Interface: Flange / end-cap slot type, mates with intake filter housing
• Sealing: Polyurethane (PU) foam gasket integrated into the media end frame for seamless zero-leak fit

Construction Materials

• Media: Micro-fiberglass
• Media Weight: Approx. 120–150 g/m²
• Support: Inner galvanized metal support mesh + 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 debonding

Operating Conditions

• Operating Temperature: Continuous -20°C to 80°C; max. 93°C (200°F)
• Relative Humidity: ≤95% RH, no condensation
• Collapse Pressure Resistance: ≥ 3.0 kPa overall differential
• Features: Low initial pressure drop, high dust holding capacity, extended replacement interval, zero-leak sealing

Service Life and Storage

• Service Life: Approx. 8000 hours (about 1 year) under standard conditions; 4000–6000 hours in high-dust environments
• Shelf Life: 36 months in original sealed packaging, dry, ambient-temperature storage

Standards Referenced

• ISO 5011: Inlet air filters for internal combustion engines and compressors — efficiency and dust capacity testing
• 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: Test methods for air filter performance (efficiency and resistance)

Maintenance and Installation

Replacement Intervals

• Standard conditions: every 8000 hours or 12 months, whichever comes first
• High-dust conditions (mining, building materials, foundries): every 4000–6000 hours
• Replace immediately when differential pressure alarm triggers (≥750 Pa)

Installation Steps

1. Shut down and isolate: Turn off main compressor power, apply lockout/tagout (LOTO), confirm the unit has fully stopped.
2. Open the intake filter housing: Release housing clamps or bolts and remove the cover.
3. Remove the old element: Pull the old ATS11057 element straight up; check for gasket residue in the housing groove.
4. Clean the housing interior: Wipe the housing wall and sealing face with a clean cloth — no dust, oil or foreign matter.
5. Inspect the new element: Verify part number ATS11057 and check media for damage and gasket for deformation.
6. Install the new element: Lower it vertically into the housing center; ensure the gasket seats evenly on the sealing face without skewing.
7. Reassemble the housing: Refit the cover and tighten bolts or clamps evenly for a gap-free seal.
8. 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 drop should read 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 of your model, provide the compressor serial number and we will match it precisely.

Q2: How is ATS11057 different from a standard rotary-screw compressor air filter?

A: Centrifugal compressors require far cleaner intake air. 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 lead to impeller fouling, dynamic balance loss and even impeller wear and scrapping.

Q3: How do I know when to replace the air filter element?

A: Replace when any of these occur: ① operating differential pressure reaches the 750 Pa alarm value; ② the 8000-hour or 12-month interval is reached; ③ visual inspection shows media damage or gasket aging and deformation.

Q4: Is ATS11057 a genuine original part?

A: 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-time order item with a standard lead time of approximately 110 days. Plan procurement in advance to avoid affecting compressor availability.
