Product Overview
The ATS11057 air filter element is a genuine Ingersoll Rand intake filter designed specifically for ATS series oil-free centrifugal compressors. Using micro-fiberglass media with 99.97% filtration efficiency at 2.0 μm, it blocks dust and particulate matter from entering the core compression chamber, protecting precision impellers and diffusers from wear while helping maintain ISO 8573-1 Class 0 oil-free air quality.
As an original factory part under the Ingersoll Rand CC (Centrifugal Compressor) product line, P266 product group, 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 minimize downtime.

Compliance 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 — determination of 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 air filter performance (efficiency and resistance)
Maintenance and Installation
Replacement Interval
- Standard conditions: every 8,000 hours or 12 months, whichever comes first
- High-dust environments (mining, building materials, foundry, etc.): every 4,000–6,000 hours
- Replace immediately when pressure drop alarm triggers (≥750 Pa)
Installation Steps
- Shut down and disconnect power: Turn off main power to the compressor, 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 seal remains in the housing groove.
- Clean the housing interior: Wipe the inner walls and sealing surfaces with a clean cloth — no dust, oil, or foreign matter.
- Inspect the new element: Verify part number ATS11057; check media for damage and seal for deformation.
- Install the new element: Place it vertically into the center of the housing, ensuring the seal sits evenly against the sealing surface without tilting.
- Reassemble the housing: Refit 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 check that the differential pressure gauge returns to normal (initial pressure drop should be 120–180 Pa).
Frequently Asked Questions
Q1: Which Ingersoll Rand compressors does ATS11057 fit?
A: ATS11057 is designed for Ingersoll Rand ATS series oil-free centrifugal compressors, 110 kW class. If you are unsure about your model, provide the compressor serial number and we will match it precisely.
Q2: What is the difference between ATS11057 and a standard screw compressor air filter?
A: Centrifugal compressors require much higher intake cleanliness than screw compressors. 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, disrupting dynamic balance and potentially leading to impeller wear and scrapping.
Q3: How do I know when to replace the air filter element?
A: Replace in three cases: ① operating pressure drop reaches the alarm value of 750 Pa; ② the 8,000-hour or 12-month interval is reached; ③ visual inspection reveals damaged media or an aged, deformed seal.
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 original Ingersoll Rand intake filter housings.
Q5: What is the lead time for ATS11057?
A: ATS11057 is a long lead time item with a standard lead time of approximately 110 days. We recommend planning your procurement in advance to avoid affecting compressor operation.
