Working Principle: Coalescing

The core of this filter element is coalescing filtration technology, which operates in three steps:

1. Pre-filtration: The outer layer of the filter element first intercepts larger solid particles and some liquid droplets.

2. Coalescing/Agglomeration: Compressed air containing fine oil mist (aerosol) and water molecules enters the high-efficiency glass fiber media deep within the filter element. As the tiny oil droplets pass through the fibers, they collide and are captured, coalescing into larger droplets.

3. Drainage: These larger droplets settle to the bottom of the filter housing under the influence of gravity and are discharged through an automatic drain or manual drain valve.

 3. Key Features and Standards

 Oil Removal Efficiency: Removal efficiency is extremely high for oil mist particles 0.01 microns and larger, typically reaching 99.99%+.  Compliant with International Standards: Its performance enables treated compressed air to achieve the highest air quality levels specified in ISO 8573-1:2010.

 Solid Particles: Typically Class 1 (≤ 0.1 µm)

 Moisture: Typically Class 4 (pressure dew point ≤ +3°C) or higher (depending on inlet air conditions)

 Oil Content: Typically Class 1 (≤ 0.01 mg/m³) or Class 2 (≤ 0.1 mg/m³)

 4. Main Applications

This filter element is used in applications requiring the highest compressed air quality to protect downstream equipment and products:

 Pneumatic Tools: Protects precision tools from wear and corrosion.

 Painting and Spraying: Prevents surface defects such as "fisheyes" on workpieces.

 Pneumatic Control Systems: Protects precision valves, cylinders, and instruments.  Material Conveying: For example, conveying powders in the food and pharmaceutical industries to prevent oil contamination.

 Instrument Breathing Air.

 Electronic Manufacturing: Chip packaging, circuit board cleaning, etc.

 Food and Beverage Industry: Although a subsequent activated carbon filter is often required, this filter element is a critical pre-oil removal step.

 

 5. Important Notes

 Installation Orientation: Coalescing filter elements must be installed vertically to ensure that condensate can be collected and drained downwards.

 Differential Pressure Monitoring: Filter elements will gradually become clogged during use, causing the inlet and outlet differential pressure (ΔP) to increase. When the differential pressure reaches the manufacturer's maximum specified value (typically 0.7-1.0 bar), the filter element must be replaced. Otherwise, energy consumption will increase and filtration efficiency will decrease.

 Pre-Filtration: To ensure its lifespan and effectiveness, a coarse filter (such as a particle filter) and a refrigerated dryer or adsorption dryer must be installed before this precision oil removal filter element to remove most of the moisture and particulate matter. Compatibility: When purchasing a replacement filter element, ensure that its size, accuracy, and interface are identical to the original filter element.

Summary: The P1404040-00202 is a high-performance coalescing oil mist filter element, a critical component for ensuring high-quality, oil-free air in compressed air systems and widely used in various industrial applications.
