Ingersoll Rand ATN72018 Air Filter Element
Product Overview
ATN72018 is a genuine Ingersoll Rand air filter element designed for the intake filtration system of ATN series 720kW oil-free centrifugal compressors. Manufactured with micro-fiberglass media, it delivers over 99.9% filtration efficiency for particles of 3.0 μm and above, blocking dust and particulate matter from entering the compression chamber. This protects 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 for Ingersoll Rand centrifugal compressor intake systems, ATN72018 is produced to Ingersoll Rand global technical standards. It 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 Parameters
1. Filtration Performance
| Parameter | Value |
|---|---|

| Beta Ratio β | β₃.₀ ≥ 1000 |
ATN72018 uses micro-fiberglass media with 99.9% efficiency at 3.0 μm, significantly higher than standard screw compressor air filters (F5, 98% @ 5 μm). It meets the high intake cleanliness requirements of high-power centrifugal compressors and protects 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 Pressure | 350–600 Pa |
| Alarm / Final Resistance | Alarm: 700 Pa; Final: 800 Pa (replace immediately) |
| 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 89% higher dust-holding capacity than comparable competitors, reducing energy consumption and extending replacement intervals in high-flow applications.

| Mounting Interface | Flange or end-cap slot type, connects to large intake filter housing |
| Sealing | Polyurethane (PU) foam gasket integrated into the end frame, seamless zero-leak fit |
4. Material Construction
| Parameter | Value |
|---|---|

| Special Features | High flow, low resistance, high dust-holding capacity, long replacement interval, zero-leak seal |
6. Service Life and Maintenance
| Parameter | Value |
|---|---|
| Service Life | Approx. 4,000–6,000 hours (8–10 months) under standard conditions; 3,000 hours in high-dust environments |
| Shelf Life | 36 months in original sealed packaging, dry, room-temperature storage |

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, 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 pressure is released.
- Open intake filter housing: Release latches or bolts, remove cover or access door.
- Remove old element: Pull the old ATN72018 element straight up; check that the gasket is not left 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 remains.
- Inspect new element: Verify part number ATN72018; check media for damage, pleats for deformation, gasket for aging.
- Install new element: Place vertically into the center of the housing; ensure the gasket seats evenly without skewing or twisting.
- Reassemble housing: Refit 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; verify pressure differential gauge reads 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 compatibility, 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 require much higher intake cleanliness and flow than screw compressors. ATN72018 uses micro-fiberglass high-efficiency media (99.9% @ 3.0 μm) and handles 50–80 Nm³/min per element, whereas standard screw compressor filters are F5 class (98% @ 5 μm) with much lower flow capacity. Using a standard filter can cause dust buildup on the impeller, disrupt dynamic balance, and lead to costly impeller damage.
Q3: How do I know when to replace the air filter element?
A: Replace when: ① operating pressure differential reaches the alarm value of 700 Pa; 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 designed to fit original Ingersoll Rand intake filter housings.
Q5: Is one filter element enough?
A: 720kW large centrifugal compressors typically use multiple elements in parallel. The exact quantity depends on the intake filter assembly specification. Provide the compressor serial number to confirm the required quantity.
