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% @ 5 μm) — meeting the high intake cleanliness demands of high-power centrifugal compressors and protecting the precision impellers and diffusers of 720kW units.
2. Flow and Pressure Drop
| Parameter | Value |
|---|---|
| Rated Air Flow | Approx. 50–80 Nm³/min (per element, for 720kW-class centrifugal units) |

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): every 3,000 hours
- Replace immediately when differential pressure alarm triggers (≥700 Pa)
Installation Steps
- Shut down and isolate power: Turn off compressor main 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 straight up; check whether the gasket remains in the housing groove.
- Clean housing interior: Wipe the housing inner wall and sealing surface with a clean cloth; ensure no dust, oil, or foreign matter.
- Inspect new element: Verify part number ATN72018, check media for damage, pleat deformation, or gasket aging.
- Install new element: Place vertically into housing center, ensuring the gasket seats evenly on the sealing surface without skew 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 confirm the differential pressure gauge returns to normal (initial pressure drop should be 250–350 Pa).
FAQ
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 whether it applies to your model, provide the compressor serial number and we will match it precisely.
Q2: How is the ATN72018 different from a standard screw compressor air filter?
A: Centrifugal compressors demand far higher intake cleanliness and flow than screw compressors. The ATN72018 uses micro-fiberglass high-efficiency media (99.9% @ 3.0 μm) and handles 50–80 Nm³/min per element, while standard screw compressor filters are only F5 (98% @ 5 μm) with flows of a few to a few dozen Nm³/min. Using a standard filter can cause dust buildup on centrifugal compressor impellers, disrupt dynamic balance, and even lead to costly impeller wear and scrapping.
Q3: How do I know when to replace the air filter element?
A: Three conditions require replacement: (1) operating differential pressure reaches the 700 Pa alarm value; (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 part, manufactured to Ingersoll Rand global technical standards and compatible with Ingersoll Rand original intake filter housings.
Q5: Is one filter element enough?
A: 720kW large centrifugal compressors typically use multiple elements in parallel in the intake filter. The exact quantity depends on the intake filter assembly specification; provide the serial number to confirm the configuration.
