Ingersoll Rand ATN72018 Air Filter Element
Product Overview
The ATN72018 air filter element is a genuine Ingersoll Rand replacement part designed specifically for ATN series 720kW oil-free centrifugal compressors. Manufactured with micro-fiberglass media, it achieves over 99.9% filtration efficiency for particles 3.0 μm and larger, effectively blocking dust and particulate matter from entering the compression chamber. This protects high-speed precision impellers and diffusers from wear, helping maintain stable ISO 8573-1 Class 0 oil-free air quality.
As a core consumable in the centrifugal compressor intake filtration system, the ATN72018 is produced to Ingersoll Rand global technical standards. It offers high flow capacity, low resistance, high dust holding capacity, and long service life — reducing energy consumption and unplanned downtime for large centrifugal compressor stations.

Technical Parameters
1. Filtration Performance (Core Metrics)
| Parameter | Value |
|---|---|
| Filtration Rating | 3.0 μm |
| Filtration Efficiency | 99.9% @ 3.0 μm |
| Filter Class | F8 (medium-high efficiency, per EN 779 / ISO 16890) |
| Dust Holding Capacity | Approx. 7.2 kg (at rated flow and final resistance) |
| Beta Ratio β | β₃.₀ ≥ 1000 |
The ATN72018 uses micro-fiberglass media with 99.9% efficiency at 3.0 μm, significantly higher than standard screw compressor air filters (F5 grade, 98% @ 5μm). It meets the stringent intake air cleanliness requirements of high-power centrifugal compressors, protecting the precision impellers and diffusers of 720kW units.
2. Flow and Resistance Parameters
| Parameter | Value |
|---|---|
| Rated Air Flow | Approx. 50–80 Nm³/min (per element, for 720kW class centrifugal units) |
| Initial Pressure Drop | Approx. 250–350 Pa (clean, at rated flow) |
| Operating Pressure Differential | 350–600 Pa |
| Alarm / Final Resistance | Alarm: 700 Pa; Final: 800 Pa (must replace) |
| Pressure Drop vs. Energy | Every 100 Pa increase in intake pressure loss raises compressor shaft power by approx. 0.35% |
The Ingersoll Rand centrifugal compressor intake filter is designed with micro-fiberglass media, achieving approximately 40% lower clean pressure drop and 89% higher dust holding capacity compared to similar competitors. This reduces energy consumption and extends replacement intervals under high-flow conditions.

| Special Features | High flow low resistance, high dust holding capacity, long replacement interval, zero-leak seal |
6. Service Life and Maintenance
| Parameter | Value |
|---|---|
| Service Life | Approx. 4,000–6,000 hours (8–10 months) under standard conditions; reduced to 3,000 hours in high-dust environments |
| Shelf Life | 36 months in original sealed packaging, dry ambient conditions |

Standard Maintenance and Installation Steps
Replacement Interval
- Standard conditions: every 4,000–6,000 hours or 8–10 months (whichever comes first)
- High-dust environments (mining, construction materials, cement, steel, etc.): every 3,000 hours
- Replace immediately when pressure differential alarm triggers (≥700 Pa)
Installation Steps
- Shut down and disconnect power: Turn off main power, apply lockout/tagout (LOTO), confirm the unit has fully stopped and pressure is released.
- Open intake filter housing: Release latches or bolts on the large intake filter housing; remove cover or access door.
- Remove old element: Pull out the old ATN72018 element vertically; check for any residual gasket in the housing groove.
- Clean housing interior: Wipe inner walls and sealing surfaces with a clean cloth; ensure no dust, oil, or foreign objects remain.
- 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; ensure gasket seats evenly on sealing surface without skew or twist.
- Reassemble housing: Replace 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 check that pressure differential 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 for Ingersoll Rand ATN series 720kW high-power oil-free centrifugal compressors. If you are unsure about your model, please provide the compressor serial number for precise matching.
Q2: How does the ATN72018 differ from standard screw compressor air filters?
A: Centrifugal compressors require much higher intake air cleanliness and flow than screw compressors. The ATN72018 uses micro-fiberglass high-efficiency media (99.9% @ 3.0μm) with a single-element flow of 50–80 Nm³/min, whereas standard screw compressor filters are only F5 grade (98% @ 5μm) with flow of a few to tens of Nm³/min. Using a standard filter can cause dust accumulation on centrifugal compressor impellers, disrupt dynamic balance, and even lead to costly impeller damage.
Q3: How do I know when to replace the air filter element?
A: Replace in three cases: ① operating pressure differential reaches the alarm value of 700 Pa; ② replacement interval of 4,000–6,000 hours or 8–10 months is reached; ③ visual inspection reveals media damage or gasket aging/deformation.
Q4: Is the ATN72018 a genuine original part?
A: The ATN72018 is a genuine Ingersoll Rand replacement part, manufactured to Ingersoll Rand global technical standards and compatible with original intake filter housings.
Q5: Is one filter element enough?
A: 720kW large centrifugal compressors typically use multiple filter elements in parallel. The exact number depends on the intake filter assembly specification. Please provide the serial number to confirm the required quantity.
