Ingersoll Rand ATN72018 Air Filter Element
Product Overview
The ATN72018 air filter element is a genuine Ingersoll Rand intake filter designed for ATN series 720kW high-capacity oil-free centrifugal compressors. Manufactured with micro-fiberglass media, it captures 99.9% of particles at 3.0 μm, preventing dust and particulates from entering the compression chamber. This protects high-speed precision impellers and diffusers from erosion, supporting stable ISO 8573-1 Class 0 oil-free air output.
As a core consumable for Ingersoll Rand centrifugal compressor intake filtration systems, the ATN72018 is built to Ingersoll Rand global technical standards. It combines high flow capacity, low resistance, high dust holding capacity, and long service life—helping large centrifugal compressor stations reduce energy consumption and unplanned downtime.

The ATN72018 uses micro-fiberglass media with 99.9% efficiency at 3.0 μm and above—significantly higher than standard screw compressor air filters (F5, 98% @ 5μm). It meets the high intake cleanliness demands of high-capacity centrifugal compressors, protecting the precision impellers and diffusers of 720kW units.
2. Flow and Pressure Drop
| Parameter | Value |
|---|---|

Standard Maintenance and Installation
Replacement Interval
- Standard conditions: every 4,000–6,000 hours or 8–10 months, whichever comes first
- High-dust conditions (mining, building materials, cement, steel, etc.): every 3,000 hours
- Replace immediately when differential pressure alarm triggers (≥700 Pa)
Installation Steps
- Shut down and isolate power: Turn off main compressor power, apply lockout/tagout (LOTO), confirm the unit has fully stopped and depressurized.
- Open intake filter housing: Release latches or bolts on the large intake filter housing, remove cover or access door.
- Remove old element: Pull the old ATN72018 element vertically upward; check whether the gasket remains in the housing groove.
- Clean housing interior: Wipe the inner walls and sealing surface with a clean cloth—no dust, oil, or foreign objects.
- Inspect new element: Verify part number ATN72018; check media for damage, pleats for deformation, and gasket for aging.
- Install new element: Place vertically into housing center, ensuring the gasket seats evenly on the sealing surface—no tilt or twist.
- Reassemble housing: Refit cover or access door, tighten bolts or latches evenly to ensure a gap-free seal.
- Start up and leak-check: Run the compressor, listen for air leaks at the intake filter, and verify differential pressure gauge reads normal (initial drop should be 250–350 Pa).
Frequently Asked Questions
Q1: Which Ingersoll Rand compressors does the ATN72018 fit?
A: The ATN72018 is designed specifically for Ingersoll Rand ATN series 720kW high-capacity oil-free centrifugal compressors. If you are unsure about your model, provide the compressor serial number and we will match it precisely.
Q2: What is the difference between the ATN72018 and a standard screw compressor air filter?
A: Centrifugal compressors demand far higher intake cleanliness and flow capacity than screw compressors. The ATN72018 uses micro-fiberglass high-efficiency media (99.9% @ 3.0 μm) with a single-element flow capacity of 50–80 Nm³/min, while standard screw compressor filters are only F5 rated (98% @ 5μm) with flow capacities of just a few to tens of Nm³/min. Using a standard filter can cause impeller fouling, dynamic imbalance, and even costly impeller damage in large centrifugal compressors.
Q3: How do I know when to replace the air filter element?
A: Three conditions require replacement: ① operating differential pressure reaches the alarm value of 700 Pa; ② the 4,000–6,000 hour or 8–10 month interval is reached; ③ visual inspection reveals media damage or gasket aging/deformation.
Q4: Is the ATN72018 a genuine OEM part?
A: The ATN72018 is a genuine Ingersoll Rand replacement part, manufactured to Ingersoll Rand global technical standards and designed to fit Ingersoll Rand original intake filter housings.
Q5: Is one filter element sufficient?
A: 720kW large centrifugal compressors typically use multiple filter elements in parallel. The exact quantity depends on the intake filter assembly specification. Provide the serial number and we will confirm the configuration quantity.
