Product Overview
ATS11057 is a genuine Ingersoll Rand air intake filter element, purpose-built for ATS series oil-free centrifugal compressors. The element uses micro-fiberglass media rated at 99.97% efficiency @ 2.0 μm, blocking dust and particulate from entering the compression chamber, protecting the impeller and diffuser from wear, and supporting ISO 8573-1 Class 0 oil-free air quality.
As an original part in the Ingersoll Rand CC (Centrifugal Compressor) product line, group P266, 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.

- GB/T 14295 — air filters
- GB/T 6165 — air filter performance test methods (efficiency and resistance)
Maintenance & Installation
Replacement Interval
- Standard conditions: every 8000 hours or 12 months, whichever comes first
- High-dust conditions (mining, building materials, foundry): every 4000–6000 hours
- Replace immediately when differential pressure alarm triggers (≥750 Pa)
Installation Steps
- Shut down and lock out — disconnect main power, apply LOTO, confirm the unit has fully stopped.
- Open the intake filter housing — release clamps or bolts and remove the cover.
- Remove the old element — pull the old ATS11057 straight out; check whether the gasket remains in the housing groove.
- Clean the housing interior — wipe the inner wall and sealing surface free of dust, oil, and foreign matter.
- Inspect the new element — verify part number ATS11057, check media for damage and gasket for deformation.
- Install the new element — seat it vertically in the housing center; ensure the gasket contacts the sealing surface evenly without skewing.
- Refit the housing — replace 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 filter, and confirm the differential pressure gauge returns to normal (initial 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, 110 kW class. If you are unsure, provide the compressor serial number and we will confirm the correct match.
Q2: How does ATS11057 differ from a standard 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 (98% @ 5 μm). Using a standard filter can cause impeller fouling, imbalance, and premature impeller wear.
Q3: How do I know when to replace the element?
A: Replace when: (1) operating differential pressure reaches the 750 Pa alarm value; (2) the 8000-hour or 12-month interval is reached; or (3) visual inspection shows damaged media or a hardened, deformed gasket.
Q4: Is ATS11057 a genuine original part?
A: Yes. ATS11057 is a genuine Ingersoll Rand original part, produced 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 purchases in advance to avoid downtime.
