Ingersoll Rand ATN72018 Air Filter Element
Product Overview
ATN72018 is a genuine Ingersoll Rand air intake filter element engineered for the ATN series 720kW high-capacity oil-free centrifugal compressor. Built with micro-fiberglass media, it achieves over 99.9% filtration efficiency at 3.0 μm, blocking dust and particulate from entering the compression chamber to protect high-speed precision impellers and diffusers — supporting stable ISO 8573-1 Class 0 oil-free air output.
As a core consumable of the centrifugal compressor intake filtration system, ATN72018 is manufactured to Ingersoll Rand global technical standards, offering high flow, low resistance, high dust-holding capacity and extended service life. It helps large centrifugal compressor stations reduce energy consumption and unplanned downtime.

Technical Specifications
1. Filtration Performance

| Beta Ratio β | β₃.₀ ≥ 1000 |
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). This meets the high intake cleanliness requirements of high-capacity centrifugal compressors, 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) |
| Initial Pressure Drop | Approx. 250–350 Pa (clean, at rated flow) |
| Operating Differential Range | 350–600 Pa |
| Alarm / Terminal Resistance | Alarm: 700 Pa; Terminal: 800 Pa (replace immediately) |
| Pressure Drop vs. Energy | Each 100 Pa inlet pressure loss increases compressor shaft power by approx. 0.35% |
The micro-fiberglass media design delivers approximately 40% lower clean pressure drop and approximately 89% higher dust holding capacity than comparable alternatives, reducing energy consumption and extending replacement intervals under high-flow conditions.

Standard Maintenance and Installation
Replacement Intervals
- Standard conditions: every 4,000–6,000 hours or 8–10 months, whichever comes first
- High-dust conditions (mining, construction materials, cement, steel): every 3,000 hours
- Replace immediately when differential pressure alarm triggers (≥700 Pa)
Installation Steps
- Shut down and disconnect power: Turn off main compressor power, apply lockout/tagout (LOTO), confirm the unit has fully stopped and pressure is released.
- Open the intake filter housing: Release latches or bolts on the large intake filter housing; remove the 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 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, pleats for deformation, gasket for aging.
- Install new element: Place vertically into the housing center; ensure 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; verify differential pressure gauge reads normal (initial drop should be 250–350 Pa).
Frequently Asked Questions
Q1: Which Ingersoll Rand compressors does ATN72018 fit?
A: ATN72018 is designed 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: How does ATN72018 differ from standard screw compressor air filters?
A: Centrifugal compressors demand far higher intake cleanliness and airflow than screw compressors. ATN72018 uses micro-fiberglass high-efficiency media (99.9% @ 3.0 μm) with 50–80 Nm³/min flow per element, while standard screw compressor filters are only F5 (98% @ 5 μm) with much lower flow. Using standard filters can lead to impeller fouling, dynamic imbalance, and costly impeller damage on large centrifugal compressors.
Q3: How do I know when to replace the air filter element?
A: Replace in three cases: (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 ATN72018 a genuine OEM part?
A: ATN72018 is a genuine Ingersoll Rand replacement part manufactured to Ingersoll Rand global technical standards, designed to fit original intake filter housings.
Q5: Is one element enough?
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 serial number to confirm configuration.
