Product Overview
ATS11057 air filter element is a genuine Ingersoll Rand intake filter element engineered specifically for ATS series oil-free centrifugal compressors. Built with micro-fiberglass media rated at 99.97% @ 2.0 μm, it blocks dust and particulate matter from entering the core compression chamber, protecting precision impellers and diffusers from wear while supporting ISO 8573-1 Class 0 oil-free air quality.
As an original accessory in 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 cut downtime for maintenance.

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 (EPA, HEPA, 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 8,000 hours or 12 months, whichever comes first
- High-dust environments (mining, building materials, foundries): every 4,000–6,000 hours
- Replace immediately when the pressure differential alarm triggers (≥750 Pa)
Installation Steps
- Shut down and lock out: switch off main power, apply lockout/tagout (LOTO), confirm the unit has fully stopped.
- Open the intake filter housing: release the housing latches or bolts and remove the cover.
- Remove the old element: pull the old ATS11057 straight up; check whether the gasket remains in the housing groove.
- Clean the housing interior: wipe the inner wall and sealing surface with a clean cloth — no dust, oil, or 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, ensuring the gasket contacts the sealing surface evenly without tilting.
- Refit the housing: replace the cover and tighten bolts or latches evenly for a gap-free seal.
- Start up and leak-check: run the compressor, listen for air leaks at the intake filter, and confirm the differential 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 in the 110 kW class. If you are unsure about your model, provide the compressor serial number and we will match the correct part for you.
Q2: How is the ATS11057 different from a standard screw compressor intake filter?
A: Centrifugal compressors demand much higher intake cleanliness. 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 impeller, disturb dynamic balance, and even lead to impeller wear and scrapping.
Q3: How do I know when to replace the filter element?
A: Three conditions require replacement: (1) operating differential reaches the 750 Pa alarm value; (2) the 8,000-hour or 12-month interval is reached; (3) visual inspection shows damaged media or an aged, deformed gasket.
Q4: Is the ATS11057 a genuine original part?
A: The ATS11057 is a genuine Ingersoll Rand original accessory, 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. Plan your procurement in advance to avoid affecting compressor operation.
