Ingersoll Rand ATN72018 Air Filter Element — Product Details
Product Overview
ATN72018 is a genuine Ingersoll Rand air filter element engineered for the intake filtration system of ATN series 720kW oil-free centrifugal compressors. Manufactured to Ingersoll Rand global technical standards, it uses micro-fiberglass media that captures 99.9% of particles at 3.0 μm, blocking dust and particulate from entering the compression chamber. This protects high-speed precision impellers and diffusers from erosion and maintains stable ISO 8573-1 Class 0 oil-free air quality.
As a core consumable in the centrifugal compressor intake filtration system, ATN72018 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.

Technical Specifications
1. Filtration Performance

| Beta Ratio β | β₃.₀ ≥ 1000 |
The micro-fiberglass media achieves 99.9% efficiency at 3.0 μm and above — well above standard screw compressor air filters (F5, 98% @ 5 μm) — meeting the high intake cleanliness demands of large centrifugal compressors and protecting the precision impeller and diffuser of 720kW units.
2. Flow and Resistance
| 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 (must replace) |
| Pressure Drop vs. Energy | Each 100 Pa increase in intake pressure loss raises compressor shaft power by approx. 0.35% |
The micro-fiberglass design delivers approximately 40% lower clean pressure drop and approximately 89% higher dust-holding capacity than comparable competitors, reducing energy consumption and extending replacement intervals under high-flow conditions.

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 lock out: Turn off main power, apply LOTO, confirm the unit has fully stopped and depressurized.
- Open the intake filter housing: Release the latches or bolts on the large intake filter housing and remove the cover or access door.
- Remove the old element: Pull the old ATN72018 element straight up. Check whether the gasket remains in the housing groove.
- Clean the housing: Wipe the inner walls and sealing surfaces with a clean cloth. Ensure no dust, oil, or foreign matter remains.
- Inspect the new element: Verify part number ATN72018, check for media damage, pleat deformation, or gasket aging.
- Install the new element: Place vertically into the housing center. Ensure the gasket seats evenly on the sealing surface without skew or twist.
- Reassemble the housing: Refit the 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 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 high-power 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 much higher intake cleanliness and airflow than screw compressors. ATN72018 uses micro-fiberglass high-efficiency media (99.9% @ 3.0 μm) with a rated flow of 50–80 Nm³/min per element, whereas standard screw compressor filters are F5 class (98% @ 5 μm) with flow of only a few to tens of Nm³/min. Using a standard filter can cause dust buildup on the impeller, disrupt dynamic balance, and lead to costly impeller wear or scrapping.
Q3: How do I know when to replace the air filter element?
A: Replace in three cases: 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 ATN72018 a genuine original part?
A: ATN72018 is a genuine Ingersoll Rand part manufactured to Ingersoll Rand global technical standards and designed to fit the original intake filter housing.
Q5: Is one filter 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 the configuration quantity.
