Ingersoll Rand ATS11057 Air Filter Element | Genuine ATS Centrifugal Compressor Intake Filter

Product Overview

The ATS11057 air filter element is a genuine Ingersoll Rand intake filter element engineered for ATS series oil-free centrifugal compressors. Using micro-fiberglass media, it achieves 99.97% filtration efficiency at 2.0 μm, blocking dust and particulate matter from entering the core compression chamber, protecting the precision impeller and diffuser from wear and supporting ISO 8573-1 Class 0 oil-free air quality.

As an original part within 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 long service life — help operators reduce energy consumption and maintenance downtime.

Technical Data

Filtration Performance

• Filtration rating: 2.0 μm

• Dust holding capacity: approx. 2.2 kg (at rated airflow, terminal resistance)
• Beta ratio: β₂.₀ ≥ 3333

With micro-fiberglass media, the ATS11057 captures 99.97% of particles at 2.0 μm and above — significantly higher than standard screw compressor air filters (F5 class, 98% @ 5 μm) — meeting the stringent intake cleanliness requirements of centrifugal compressors.

Flow and Resistance

• Rated 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 pressure range: 180–600 Pa
• Alarm / terminal resistance: alarm at 750 Pa; terminal at 1000 Pa (must replace)
• Pressure drop vs. energy: every 100 Pa increase in inlet pressure loss raises compressor shaft power by approx. 0.35%

According to Ingersoll Rand data, this intake filter series offers a clean pressure drop 40% lower and dust holding capacity 89% higher than comparable alternatives, reducing operating energy consumption and extending replacement intervals.

Dimensions and Installation

• Dimensions: approx. φ350 × φ180 × 320 mm (outer diameter × inner diameter × height)
• Effective filtration area: approx. 8–10 m² (pleated cartridge unfolded area)
• Pleats / pleat spacing: approx. 150–180 pleats, spacing approx. 6–8 mm
• Mounting interface: flange / end-cap slot type, mating with the intake filter housing
• Sealing: polyurethane (PU) foam gasket integrated into the media end frame for seamless, zero-leak fit

Materials of Construction

• Media: micro-fiberglass
• Media weight: approx. 120–150 g/m²
• Inner / outer support: galvanized metal support mesh inside, protective mesh outside, preventing media collapse
• End caps: polystyrene frame — lightweight, corrosion-resistant, incinerable
• Seal: one-piece polyurethane (PU) foam gasket, high elasticity, seamless fit
• Bonding: polyurethane adhesive bonding end caps to media, heat-resistant, no debonding

Operating Conditions

• Operating temperature: continuous -20°C to 80°C; maximum 93°C (200°F)
• Relative humidity: ≤95% RH, no condensation
• Collapse / burst pressure resistance: overall collapse differential pressure ≥ 3.0 kPa
• Special features: low initial pressure drop, high dust holding capacity, long 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, at room temperature and dry conditions

Standards

• ISO 5011: inlet air filter performance testing for internal combustion engines and compressors (efficiency and dust holding capacity)
• ISO 16889: determination of beta ratio for hydraulic transmission 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 Intervals

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

Installation Steps

1. Shut down and disconnect power: switch off the compressor main power, apply lockout/tagout (LOTO), and confirm the unit has fully stopped.
2. Open the intake filter housing: release the housing clips or bolts and remove the cover.
3. Remove the old element: pull the old ATS11057 element straight up and check whether the gasket remains in the housing groove.
4. Clean the housing interior: wipe the inner wall and sealing surface with a clean cloth; ensure no dust, oil or foreign matter remains.
5. Inspect the new element: verify part number ATS11057 and check the media for damage and the gasket for deformation.
6. Install the new element: place it vertically in the center of the housing, ensuring the gasket seats evenly on the sealing surface without skewing.
7. Refit the housing: reinstall the cover and tighten bolts or clips 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 pressure drop should be 120–180 Pa).

FAQ

Q1: Which Ingersoll Rand compressors does the ATS11057 fit?

A: The ATS11057 is designed for Ingersoll Rand ATS series oil-free centrifugal compressors, 110 kW class. If you are unsure whether it fits your machine, provide the 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 dust buildup on the centrifugal impeller, 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 cases: (1) operating differential pressure reaches the 750 Pa alarm value; (2) the 8000-hour or 12-month interval is reached; (3) visual inspection reveals media damage or a hardened, deformed gasket.

Q4: Is the ATS11057 a genuine original part?

A: The ATS11057 is a genuine Ingersoll Rand original part, manufactured to Ingersoll Rand global technical standards and compatible with Ingersoll Rand original 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 procurement in advance to avoid impacting compressor operation.
