Ingersoll Rand ATN72018 Air Filter Element — Product Details
1. Product Overview
ATN72018 is a genuine Ingersoll Rand air intake filter element engineered for ATN-series 720kW oil-free centrifugal compressors. Built with micro-fiberglass media, it captures 99.9% of particles at 3.0 μm, preventing dust and particulate from entering the compression chamber and protecting high-speed precision impellers and diffusers from erosion. This supports stable delivery of ISO 8573-1 Class 0 oil-free air.
As a core consumable in the centrifugal compressor intake filtration system, ATN72018 is manufactured to Ingersoll Rand global technical standards. It combines high flow capacity with low resistance, high dust-holding capacity and long service life — helping large centrifugal compressor stations reduce energy consumption and unplanned downtime.

3. Technical Specifications
3.1 Filtration Performance (Core Metrics)
| Parameter | Value |
|---|---|
| Filtration Rating | 3.0 μm |

| Dust-Holding Capacity | Approx. 7.2 kg (at rated flow, terminal pressure drop) |
| Beta Ratio β | β₃.₀ ≥ 1000 |
With micro-fiberglass media, ATN72018 achieves 99.9% efficiency at 3.0 μm — well above standard screw compressor air filters (F5, 98% @ 5 μm). This meets the high intake cleanliness requirements of high-power centrifugal compressors, protecting the precision impellers and diffusers of 720kW units.
3.2 Flow and Pressure Drop
| Parameter | Value |
|---|---|
| Rated Air Flow | Approx. 50–80 Nm³/min (per element, for 720kW centrifugal units) |
| Initial Pressure Drop | Approx. 250–350 Pa (clean, at rated flow) |
| Operating Differential Range | 350–600 Pa |
| Alarm / Terminal Pressure Drop | Alarm: 700 Pa; Terminal: 800 Pa (replace immediately) |
| Pressure Drop vs. Energy | Each 100 Pa increase in intake 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 alternatives, reducing energy consumption and extending replacement intervals in high-flow applications.

| Support Grid | Inner galvanized metal support mesh + outer protective mesh to prevent media collapse |
| End Caps | Polystyrene frame — lightweight, corrosion-resistant, incinerable |
| Gasket | One-piece polyurethane (PU) foam gasket, high elasticity, seamless fit |
| Adhesive | Polyurethane adhesive bonding end caps to media; high-temperature resistant, no debonding |

| Relative Humidity | ≤95% RH, non-condensing |
| Collapse Pressure Resistance | ≥ 2.8 kPa overall |
| Special Features | High flow low resistance, high dust-holding capacity, long replacement interval, zero-leak seal |
3.6 Service Life and Maintenance
| Parameter | Value |
|---|---|
| Service Life | Approx. 4,000–6,000 hours (8–10 months) under standard conditions; reduced to 3,000 hours in high-dust environments |
| Shelf Life | 36 months in original sealed packaging, dry ambient conditions |

4. Standard Maintenance and Installation Steps
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 drop 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 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 for any gasket residue 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, and gasket for aging.
- Install new element: Place the new element vertically into the housing center; ensure the gasket seats evenly on the sealing surface without skewing or twisting.
- Reassemble 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 verify the pressure differential gauge returns to normal (initial pressure drop should be 250–350 Pa).
5. Frequently Asked Questions
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 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 require much higher intake cleanliness and flow capacity than screw compressors. ATN72018 uses micro-fiberglass media (99.9% @ 3.0 μm) with a single-element flow of 50–80 Nm³/min, whereas standard screw compressor filters are F5 (98% @ 5 μm) with flow of only a few to tens of Nm³/min. Using a standard filter can cause dust buildup on large centrifugal compressor impellers, disrupt dynamic balance, and even lead to costly impeller damage.
Q3: How do I know when to replace the air filter element?
A: Replace in three cases: ① operating pressure drop 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 OEM part?
A: ATN72018 is a genuine Ingersoll Rand part manufactured to Ingersoll Rand global technical standards and fits original Ingersoll Rand intake 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 intake filter assembly specification; provide the compressor serial number to confirm the configuration.
