Ingersoll Rand ATN72018 Air Filter Element
Product Overview
The ATN72018 air filter element is a genuine Ingersoll Rand inlet filter element designed for ATN series 720kW high-power oil-free centrifugal air compressors. Manufactured with micro-fiberglass filter media, it achieves over 99.9% filtration efficiency for particles at 3.0 μm, effectively blocking dust and particulate matter from entering the compression chamber. This protects the high-speed precision impellers and diffusers from wear, helping maintain stable ISO 8573-1 Class 0 oil-free air quality.
As a core spare part of the Ingersoll Rand centrifugal compressor inlet 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 — helping large centrifugal compressor stations reduce energy consumption and unplanned downtime.

The ATN72018 uses micro-fiberglass media with 99.9% efficiency at 3.0 μm, significantly higher than standard screw compressor air filters (F5 class, 98% @ 5 μm). It meets the high inlet air cleanliness requirements of high-power 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 Pressure Differential | 350–600 Pa |
| Alarm / Terminal Pressure Drop | Alarm: 700 Pa; Terminal: 800 Pa (replace immediately) |
| Pressure Drop vs. Energy | Every 100 Pa increase in inlet pressure loss raises compressor shaft power by approx. 0.35% |
Designed with micro-fiberglass media, the Ingersoll Rand centrifugal compressor inlet filter has a clean pressure drop approximately 40% lower than comparable competitors and dust-holding capacity approximately 89% higher, reducing energy consumption and extending replacement intervals under high-flow conditions.

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

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, building materials, cement, steel, etc.): every 3,000 hours
- Replace immediately when pressure differential alarm triggers (≥700 Pa)
Installation Steps
- Shut down and lock out: Turn off main power, apply lockout/tagout (LOTO), confirm the unit has fully stopped and depressurized.
- Open inlet filter housing: Release latches or bolts on the large inlet filter housing, remove cover or access door.
- Remove old element: Pull the old ATN72018 element vertically upward; check whether the gasket remains in the housing groove.
- Clean housing interior: Wipe the inner walls and sealing surfaces with a clean cloth; ensure no dust, oil, or foreign matter.
- Inspect new element: Verify part number ATN72018; check media for damage, pleat deformation, and gasket aging.
- Install new element: Place vertically into the housing center, ensuring the gasket seats evenly on the sealing surface without skewing or twisting.
- Reassemble housing: Reinstall 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 inlet filter, and verify the pressure differential 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 about compatibility, provide the compressor serial number and we will match it precisely.
Q2: What is the difference between the ATN72018 and a standard screw compressor air filter?
A: Centrifugal compressors require much higher inlet air cleanliness and flow than screw compressors. The ATN72018 uses micro-fiberglass high-efficiency media (99.9% @ 3.0 μm) with a single-element flow of 50–80 Nm³/min, while standard screw compressor filters are only F5 class (98% @ 5 μm) with flow of a few to tens of Nm³/min. Using a standard filter can cause impeller fouling, dynamic imbalance, and even costly impeller wear and scrapping.
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 OEM part?
A: The ATN72018 is a genuine Ingersoll Rand part, manufactured to Ingersoll Rand global technical standards and compatible with original Ingersoll Rand inlet filter housings.
Q5: Is one filter element enough?
A: 720kW large centrifugal compressors typically use multiple filter elements in parallel. The exact quantity depends on the inlet filter assembly specification. Provide the compressor serial number to confirm the configuration quantity.
