ZS1238408 D8/23291 Coalescing Filter Element – Technical Specifications & Application Guide

1. Product Overview

The ZS1238408 D8/23291 is a high-performance coalescing filter element designed for compressed air systems, primarily used to remove oil aerosols, water droplets, and fine solid particles from compressed air streams. It employs advanced coalescence technology to ensure clean, dry air output, protecting downstream equipment (e.g., pneumatic tools, valves, cylinders) from contamination and extending their service life. Compliant with international standards (e.g., ISO 8573-1 for air purity), this filter element is suitable for industrial applications requiring reliable oil-water separation.

3. Design & Construction Features

The ZS1238408 D8/23291 is engineered for durability and efficiency, with the following key design elements:

• Multi-Layer Filter Media: Combines a pre-filtration layer (to capture large particles), a coalescing layer (to merge small oil/water droplets into larger ones), and a hydrophobic layer (to repel water and ensure dry air output). This layered structure optimizes separation efficiency while minimizing pressure drop.

  
  

• Robust End Caps: Made of reinforced polypropylene (PP) to withstand mechanical stress and ensure a secure fit in the filter housing.

  
  

• Anti-Static Treatment: The filter media is treated with an anti-static agent to prevent static electricity buildup, reducing the risk of fire in explosive environments.

  
  

• Drainage System: An integrated sump at the bottom of the element collects separated oil and water, which is automatically discharged via a drain valve (included in the filter assembly).

  
  

4. Primary Functions & Benefits

This coalescing filter element serves critical roles in compressed air systems, delivering the following benefits:

1. Oil-Water Separation: Effectively removes oil aerosols (≥0.3 µm) and water droplets from compressed air, ensuring compliance with strict air purity standards (e.g., ISO 8573-1 Class 1). This protects downstream equipment from corrosion, clogging, and malfunction.

   
   

2. Energy Efficiency: The low-pressure-drop design reduces the load on the compressor, resulting in energy savings of up to 10% compared to conventional filters.

   
   

3. Extended Service Life: The high-capacity filter media and automatic bypass valve minimize maintenance requirements, with a recommended replacement interval of 6–12 months (depending on operating conditions).

   
   

4. Versatility: Suitable for a wide range of industrial applications, including manufacturing, food processing, pharmaceuticals, and automotive, where clean compressed air is essential.

   
   

5. Application Areas

The ZS1238408 D8/23291 is ideal for the following industrial applications:

• Manufacturing: Pneumatic tools, CNC machines, and assembly lines.

  
  

• Food & Beverage: Packaging equipment, bottling lines, and food processing machinery (requires oil-free air to meet hygiene standards).

  
  

• Pharmaceuticals: Tablet presses, sterilization equipment, and cleanroom environments.

  
  

• Automotive: Paint shops, tire inflation systems, and vehicle assembly lines.

  
  

6. Installation & Maintenance Guidelines

Installation Steps

1. Shutdown & Depressurization: Turn off the compressed air system and relieve pressure from the filter housing to avoid injury.

   
   

2. Remove Old Filter: Use a filter wrench to loosen the old filter element (counterclockwise rotation) and carefully remove it from the housing.

   
   

3. Clean Housing: Wipe the filter housing with a clean, lint-free cloth to remove dirt, oil, or debris (prevents contamination of the new filter).

   
   

4. Install New Filter: Apply a thin layer of silicone grease to the new filter’s seal (ensures a tight seal). Insert the filter into the housing and rotate clockwise until hand-tight. Tighten an additional 1/4 turn with a wrench (avoid over-tightening).

   
   

5. Test for Leaks: Reconnect the compressed air supply and check the filter housing for leaks. Tighten the filter if necessary.

   
   

Maintenance Best Practices

• Regular Inspection: Check the filter housing and seal monthly for signs of wear, corrosion, or damage.

  
  

• Pressure Drop Monitoring: Install a differential pressure gauge to track filter blockage. Replace the filter when the pressure drop exceeds 1.0 bar (14.5 PSI) (indicates clogging).

  
  

• Replacement Interval: Replace the filter every 6–12 months (or as recommended by the equipment manufacturer). Adjust the interval based on operating conditions (e.g., dusty environments may require more frequent replacements).

  
  

• Oil Analysis: Perform regular oil sampling of the separated oil to monitor contamination levels (helps optimize filter replacement intervals).
