3-in-1 Compressed Air Filter for Water, Oil, and Oil Mist Filtration in Compressed Air Systems
The 3-in-1 Multi-Dry Filter from MAEDA SHELL SERVICE is a high-performance compressed air filter designed to remove water, moisture, oil, oil mist, and contaminants from compressed air systems. With a 3-stage filtration system in a single unit, it ensures cleaner, drier, and more stable compressed air.
It is suitable for factories and industries requiring high-quality compressed air, such as CNC machines, NC machines, paint sprayers, electronic component manufacturing plants, precision measuring instruments, Leak Testers, cleanroom air systems, and medical equipment.
Why are these factories interested? Clean compressed air reduces machine damage, lowers maintenance costs, increases production process accuracy, reduces waste, and effectively extends the lifespan of equipment in the compressed air system.
Is there water and oil in your compressed air?
In factory compressed air systems, contamination by water, moisture, oil, or oil mist can directly affect production quality and machine lifespan, for example:
- Valves, cylinders, and pneumatic equipment wear out quickly.
- Machines operate unstably or unexpectedly shut down.
- Precision measuring instruments, such as CMMs or Leak Testers, provide inaccurate readings.
- Paint jobs exhibit defects, such as speckling, mottling, or uneven surfaces.
- Rust or damage occurs in the piping system.
- Increased maintenance costs and expenses from production line downtime.
- Increased waste in the production process.
Installing an efficient compressed air filter is crucial for maintaining system quality, reducing damage, and enhancing production process stability.
Key Features of the 3-in-1 Multi-Dry Filter
🌀 High-Efficiency 3-in-1 Filtration System
The 3-in-1 Multi-Dry Filter uses three types of filter elements working together in a single unit: First Element, Second Element, and Oil Mist Element, to separate water, moisture, oil, and oil mist from the compressed air system. It can capture particles as small as 0.01 microns (µm) and remove up to 99.99% of oil mist, ensuring clean, dry compressed air and effectively reducing contaminants in the system.
🌪️ Tornado Dry System for Air Drying
The second filter element is made from special cotton fabric with numerous small pores. As air passes through, it creates a swirling motion similar to a tornado, causing a pressure differential that rapidly evaporates water droplets. This principle helps produce drier compressed air than conventional filtration systems, making it ideal for applications requiring strict moisture control in compressed air systems.
⚡ Reduces Pressure Loss, Saves Energy
The filter is designed with a pressure drop approximately 30–50% lower than typical oil filters, reducing the workload on the compressed air system, lowering energy consumption, and helping to reduce CO₂ emissions. With less pressure drop, the compressed air system operates more stably, and long-term energy costs are reduced.
🔧 Easy Filter Replacement, Reduced Maintenance Time
The threaded structure allows for easy removal and replacement of filter elements for cleaning without the need for tools. It takes approximately 20 seconds, reducing maintenance time and minimizing impact on production.
📊 Convenient Filter Replacement Cycle Monitoring
Standard models come with two pressure gauges, allowing users to easily monitor pressure differences to determine the optimal time for filter replacement. (Note: Model T-103A-1000 does not have pressure gauges)
Filter Elements of the 3-in-1 Multi-Dry Filter

The 3-in-1 Multi-Dry Filter from MAEDA SHELL SERVICE uses three types of filter elements working together in a single unit to progressively remove water, moisture, oil, oil mist, and contaminants from the compressed air system. This results in clean, dry compressed air suitable for industrial applications requiring high air quality.
First Element
The First Element separates water, oil, and large particles in the initial stage before the compressed air passes into subsequent filter elements. This reduces the load on the inner filters and extends the overall lifespan of the filtration system.
This filter element can be washed with water and reused, or replaced according to the manufacturer's recommended maintenance schedule.
Second Element
The Second Element is a filter for drying compressed air using the Tornado Dry principle. As air passes through, it creates a swirling motion similar to a tornado, accelerating the evaporation of water droplets and reducing residual moisture in the compressed air system.
This filter stage is crucial for producing drier compressed air than conventional filtration systems, making it suitable for applications that require reducing water problems in air systems, such as CNC machines, measuring instruments, and paint spraying.
Oil Mist Element
The Oil Mist Element removes oil mist and small particles in the final stage. It can filter particles down to 0.01 µm and remove up to 99.99% of oil mist.
This filter stage ensures highly clean compressed air, reducing the risk of oil or contaminants entering machinery, measuring instruments, or production processes that require exceptional cleanliness.
How the 3 Filter Stages Work Together
When all three filter elements work together, the compressed air system can remove water, moisture, oil, oil mist, and small particles in a single unit, reducing installation complexity and ensuring more consistent compressed air quality.
