What Is an Leaf Disc Filter?

Multilayer Sintered Filter Disc

A leaf disc filter is a precision industrial filtration component designed to remove impurities from liquids, polymers and gases. It is a circular or leaf-shaped filtration component made from sintered stainless steel mesh layers. The multilayer sintered filter disk is created by bonding multiple mesh layers through high-temperature sintering to form a strong and porous filtration structure. 

Compared to traditional mesh filters, the sintered filter leaf discs provide the following advantages:

  • Precise micron filtration accuracy
  • Excellent mechanical strength
  • High pressure resistance
  • Long service life
  • Reliable performance on industrial filtration 

This makes the stainless steel filter disc ideal for continuous industrial operations.

Structure of Multilayer Sintered Leaf Disc Filter?

The structure consists of several bonded mesh layers that work together to provide efficient filtration performance.

Typical layers include:

  • Protective layer
  • Filtration layer
  • Support layer
  • Reinforcement layer 

This multilayer design ensures the filter maintains structural integrity even under high pressure and temperature conditions.

Benefits of Using Leaf Disc Filter?

Installing a high-quality leaf disk filter can provide numerous advantages in industrial filtration systems.

1. High Filtration Precision

The multilayer sintered leaf disc filter provides micron-level filtration, ensuring removal of fine particles and contaminants.

2. Long Service Life

Durable stainless steel construction ensures the stainless steel leaf disc filter lasts significantly longer than traditional filter mesh.

3. Better Corrosion Resistance

The industrial filter disc resists corrosion from chemicals, oils,gas and solvents.

4. High Pressure Resistance

The sintered structure allows the sintered leaf disc filter to bear high operating pressure.

While our leaf disc filters can provide exceptional precision for high-pressure polymer processing, some high-volume production lines may also require automated filtration systems. For such applications, using a Continuous Belt Screen can significantly reduce downtime by automating the screen-changing process.”
