The micro-fiberglass media achieves 99.9% efficiency at 3.0 μm—well above standard screw compressor intake filters (F5, 98%@5μm)—meeting the high intake cleanliness demands of 720kW centrifugal units and protecting precision impellers and diffusers.
Flow & Resistance
| Parameter | Value |

Maintenance & 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 lock out: Disconnect main power, apply LOTO, confirm the unit is fully stopped and depressurized.
- Open the intake filter housing: Release latches or bolts, remove the cover or access door.
- Remove the old element: Pull the old ATN72018 straight up; check for any residual gasket in the housing groove.
- Clean the housing interior: Wipe the inner walls and sealing surface free of dust, oil, and foreign matter.
- Inspect the new element: Verify part number ATN72018, check media for damage, pleats for deformation, gasket for aging.
- Install the new element: Place vertically in the housing center; ensure the gasket seats evenly without skew or twist.
- Reassemble the housing: Refit the cover or access door; 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 pressure gauge returns to normal (initial drop should be 250–350 Pa).
FAQ
Q1: Which Ingersoll Rand compressors does ATN72018 fit?
A: ATN72018 is designed for Ingersoll Rand ATN series 720kW oil-free centrifugal compressors. If you are unsure about your model, provide the compressor serial number and we will match it precisely.
Q2: How is ATN72018 different from a standard screw compressor air filter?
A: Centrifugal compressors demand far higher intake cleanliness and flow than screw compressors. ATN72018 uses micro-fiberglass media (99.9%@3.0μm) with a single-element flow of 50–80 Nm³/min, while standard screw filters are F5 (98%@5μm) with only a few to tens of Nm³/min. Using a standard filter can cause impeller fouling, dynamic imbalance, and costly impeller wear.
Q3: How do I know when to replace the air filter element?
A: Replace when: ① operating differential pressure reaches the 700 Pa alarm; ② the 4,000–6,000 hour or 8–10 month interval is reached; ③ visual inspection shows media damage or gasket aging/deformation.
Q4: Is ATN72018 a genuine original part?
A: ATN72018 is a genuine Ingersoll Rand original part, manufactured to Ingersoll Rand global technical standards and compatible with Ingersoll Rand original intake filter housings.
Q5: Is one filter element enough for a 720kW centrifugal compressor?
A: Large 720kW centrifugal compressor intake filters typically use multiple elements in parallel. The exact quantity depends on the intake filter assembly specification. Provide the compressor serial number to confirm the configuration quantity.
