Ingersoll Rand ATN72018 Air Filter Element
Product Overview
ATN72018 is a genuine Ingersoll Rand air intake filter element engineered for ATN-series 720kW oil-free centrifugal compressors. The element uses micro-fiberglass media rated at 99.9% filtration efficiency for particles of 3.0 μm and above, preventing dust and particulate matter from entering the compression chamber. This protects the 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 Ingersoll Rand centrifugal compressor intake filtration system, 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 (Core Indicators)
| Parameter | Value |
|---|---|
| Filtration Rating | 3.0 μm |
| Filtration Efficiency | 99.9% @ 3.0 μm |
| Filter Class | F8 (medium-high efficiency, per EN 779 / ISO 16890) |
| Dust-Holding Capacity | Approx. 7.2 kg (at rated flow and terminal pressure drop) |
| 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 grade, 98% @ 5 μm). This 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 Range | 350–600 Pa |
| Alarm / Terminal Pressure Drop | Alarm: 700 Pa; Terminal: 800 Pa (must replace) |
| Pressure Drop vs. Energy | Every 100 Pa increase in intake pressure loss raises compressor shaft power by approx. 0.35% |
The Ingersoll Rand centrifugal compressor intake filter design uses micro-fiberglass media with a clean pressure drop approximately 40% lower than comparable alternatives and dust-holding capacity approximately 89% higher. This reduces energy consumption and extends replacement intervals under high-flow conditions.

| Effective Filtration Area | Approx. 25–30 m² (pleated cartridge expanded area) |
| Pleats / Pleat Spacing | Approx. 300–350 pleats, spacing approx. 6–7 mm |
| Mounting Interface | Flange / end-cap groove type, mates with large intake filter housing |
| Sealing | Polyurethane (PU) foam gasket, integrated into filter end frame, seamless zero-leak fit |
4. Material Construction
| Parameter | Value |
|---|---|
| Filter Media | Micro-fiberglass |
| Media Weight | Approx. 120–150 g/m² |
| Inner/Outer Support | Galvanized metal inner support mesh + outer protective mesh, prevents media collapse |
| End Caps | Polystyrene frame, lightweight, corrosion-resistant, incinerable |
| Seal | Polyurethane (PU) integrally foamed gasket, high elasticity, seamless fit |
| Adhesive | Polyurethane adhesive bonds end caps to media, high-temperature resistant, no debonding |

| Collapse Pressure Resistance | Overall collapse differential pressure ≥ 2.8 kPa |
| 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 (approx. 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 temperature |

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 the main power, apply lockout/tagout (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 and check whether the gasket remains in the housing groove.
- Clean the housing interior: Wipe the inner walls and sealing surfaces with a clean cloth to remove dust, oil and foreign matter.
- Inspect the new element: Verify part number ATN72018, check media for damage, pleats for deformation and gasket for aging.
- Install the new element: Place the new element vertically into the center of the housing, ensuring the gasket seats evenly on the sealing surface without skew or twisting.
- Reassemble the housing: Reinstall the cover or access door and evenly tighten bolts or secure latches for 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 pressure drop should be within 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-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 require much higher intake cleanliness and flow than screw compressors. 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 F5 grade (98% @ 5 μm) with only a few to tens of Nm³/min. Using a standard filter can cause dust buildup on centrifugal compressor impellers, disrupt dynamic balance and even lead to costly impeller wear and scrapping.
Q3: How do I know when to replace the air filter element?
A: Replace when: (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; or (3) visual inspection reveals media damage or a hardened, deformed gasket.
Q4: Is ATN72018 a genuine original part?
A: ATN72018 is a genuine Ingersoll Rand part produced 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 filter elements in parallel. The exact quantity depends on the intake filter assembly specification. Provide the compressor serial number to confirm the required configuration.
