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

Product Overview

ATS11057 air filter element is a genuine Ingersoll Rand inlet filter element designed and manufactured specifically for ATS series oil-free centrifugal compressors. Featuring micro-fiberglass filter media with 99.97% @ 2.0 μm filtration efficiency, it effectively blocks dust and particulate matter from entering the core compression chamber, protecting precision impellers and diffusers from wear and ensuring ISO 8573-1 Class 0 oil-free air quality.

As an original accessory of the Ingersoll Rand CC (Centrifugal Compressor) product line, P266 product group, the ATS11057 is produced to Ingersoll Rand's global technical standards, offering three core advantages: low initial pressure drop, high dust holding capacity, and long service life — helping users reduce energy consumption and minimize downtime for maintenance.

Basic Specifications

Technical Specifications

1. Filtration Performance (Core Metrics)

The ATS11057 uses micro-fiberglass media with 99.97% efficiency for particles 2.0 μm and larger, significantly exceeding standard screw compressor air filters (F5 grade, 98% @ 5 μm), meeting the stringent inlet air cleanliness requirements of centrifugal compressors.

2. Flow and Pressure Drop

Ingersoll Rand data indicates this series of inlet filters has a clean pressure drop 40% lower than comparable competitors and 89% higher dust holding capacity, effectively reducing compressor energy consumption and extending replacement intervals.

7. Compliance Standards

• ISO 5011: Inlet air cleaning equipment for internal combustion engines and compressors — performance testing
• ISO 16889: Hydraulic fluid power filters — multi-pass method for evaluating filtration performance
• 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 Steps

Replacement Interval

• Standard conditions: every 8,000 hours or 12 months, whichever comes first
• High-dust conditions (mining, construction materials, foundry, etc.): every 4,000–6,000 hours
• Replace immediately when differential pressure alarm triggers (≥750 Pa)

Installation Steps

1. Shut down and lock out: Turn off main power to the compressor, apply lockout/tagout (LOTO), confirm the unit has fully stopped.
2. Open the inlet filter housing: Release the housing latches or bolts and remove the cover.
3. Remove the old element: Pull the old ATS11057 element straight up and out; check whether the gasket remains in the housing groove.
4. Clean the housing interior: Wipe the inner walls and sealing surfaces with a clean cloth; ensure no dust, oil, or foreign matter remains.
5. Inspect the new element: Verify the new part number ATS11057; check for media damage or gasket deformation.
6. Install the new element: Place the new element vertically into the center of the housing; ensure the gasket seats evenly on the sealing surface without tilting.
7. Reassemble the housing: Refit the cover and tighten bolts or latches evenly to ensure a gap-free seal.
8. Start up and leak-check: Run the compressor, listen for air leaks at the inlet filter, and check that 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 specifically for Ingersoll Rand ATS series oil-free centrifugal compressors in the 110 kW power range. If you are unsure whether it fits your model, provide the compressor serial number and we will match it precisely.

Q2: What is the difference between the ATS11057 and a standard screw compressor air filter?

A: Centrifugal compressors require much higher inlet air 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 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 situations: (1) operating differential pressure reaches the alarm value of 750 Pa; (2) the 8,000-hour or 12-month replacement interval is reached; (3) visual inspection reveals media damage or gasket aging/deformation.

Q4: Is the ATS11057 a genuine original part?

A: The ATS11057 is a genuine Ingersoll Rand original accessory, manufactured to Ingersoll Rand's global technical standards, and fits the original Ingersoll Rand inlet filter housing.

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 your procurement in advance to avoid affecting compressor operation.
