Leaf Disc Filter

A leaf disc filter, also referred to as a polymer melt filter, is a precision filtration component fabricated from sintered stainless steel wire mesh laminate or sintered non-woven felt media, specifically engineered for high-temperature, high-viscosity, and corrosive polymer melt applications. With its large filtration area, structural durability, and extended service life, the leaf disc filter serves as an ideal solution for polymer filtration processes. As a manufacturer of leaf disc filters, we offer tailored solutions to meet the specific technical and performance requirements of partner filtration systems—from raw material selection to practical implementation—thereby optimizing user experience and minimizing operational costs. Should you wish to explore the technical specifications or potential collaboration opportunities regarding leaf disc filters, please do not hesitate to contact us.

Leaf Disc Filter Operating Principle

Install multiple pre-mounted leaf disc filters into the horizontal filter housing. The fluid containing contaminants enters through the inlet and flows simultaneously to the industrial filter elements via the top and bottom channels. Gel-like impurities in the fluid are intercepted on the surface of the industrial filter element, while the purified fluid passes through the central orifice of the filter element into the central tube and is ultimately discharged through the outlet of the vessel.

Leaf Disc Filter Media Materials

Fiber sintered felt:

Excellent filtration performance with high permeability, suitable for precision filtration.

Multi-layer sintered wire mesh:

High strength and superior filtration accuracy, ideal for high-pressure environments.

Sintered metal woven mesh:

Exceptional flexibility, suitable for industrial filters with complex shapes.

Leaf Disc Filter Structure

Leaf Disc Filter Features and Advantages

High filtration surface area

The dense arrangement and stacked configuration of leaf disc filters yield a large filtration area per unit volume, effectively minimizing the risk of polymer degradation.

Excellent filtration performance

With uniform pore size down to sub-micron levels, leaf disc filters ensure high filtration efficiency and enhanced precision through cake-assisted filtration.

High temperature and corrosion resistance

Constructed from premium stainless steel, leaf disc filters withstand high temperatures, corrosion, and acid/alkali extremes while maintaining stable operation with precise filtration and zero media leakage.

Superior mechanical strength

The durable stainless steel construction offers excellent durability, rigidity, and impact resistance, capable of withstanding high pressure without deformation or damage.

Leaf Disc Filter Quality Control System

Raw Material Control

All metal raw materials undergo chemical and physical testing to ensure that only qualified materials enter the workshop for production.

In-process Inspection

All molds and equipment undergo calibration to achieve minimal tolerances, ensuring compliance with order specifications and industry standards. Additionally, sampling inspections are conducted throughout the manufacturing process.

Finished Product Inspection

All metal filters undergo performance testing prior to warehousing and packaging. Bubble Test can be performed upon customer request to verify the sealing integrity of welds and joints. Products that pass inspection are stored in designated areas awaiting packaging and shipment.

Document Traceability

Guangtong employs unique coded tracking documents for each metal filter element from raw material intake. This system provides data support to ensure full traceability and order transparency at every stage, effectively reducing equipment downtime and mitigating quality issues.

Packaging

After thorough inspection, metal filter elements are packaged using plastic film and plywood cases to prevent damage during transportation.

Shipping

We collaborate with reliable freight forwarders to closely monitor logistics information for each shipment. Real-time tracking of delivery status ensures the safe and efficient arrival of every batch of metal filter elements, which remains our long-standing operational principle.

Customer Testimonials

Alexandra

US market

Our beverage factory has strict requirements for food safety, Guangtong customized a stainless steel pleated filter element for our filtration equipment, which exceeded our expectations completely. The R&D team of Guangtong had detailed communication with us to confirm the details on the drawings (including dimensions, material, filtration accuracy, etc.). This stainless steel pleated filter element fully meets our requirements. Its surface is polished to a mirror finish (roughness of 0.4 microns), and there are no installation problems. During use, it can effectively remove impurities from the juice while retaining the original flavor. The 3l6L stainless steel material enables it to withstand repeated high-temperature sterilization and maintain stable filtration accuracy, with a filtration efficiency of 99.6%, this has significantly enhanced our production efficiency and enabled us to successfully pass the FDA inspection. The rapid response mechanism, the professional R&D team, and the rigorous quality control have facilitated our subsequent collaboration and enabled us to become long-term partners.

Oliver Fuchs

European market

As a chemical enterprise, we established contact with Guangtong this year and inquired about a metal sintered filter element. Guangtong provided a complete ISO certificate and customized a sintered filter with high temperature tolerance up to 200 degrees Celsius based on our filter medium drawings. This sintered filter has been in use for 6 months and has not shown any leakage. Compared with previous sintered filter suppliers, its maintenance cost has been reduced by 40%. For an enterprise with customization needs like ours, we highly recommend it!

Afri o.

Southeast Asian market

Guangtong has specially designed a large-capacity stainless steel mesh filter for our municipal water treatment project in Indonesia. This stainless steel filter has a large filtration area and a processing capacity of up to 500L/h, fully meeting our requirements for filtration efficiency and accuracy. It has been operating stably for one year without any deformation or clogging issues, and the maintenance cost is also low. We highly appreciate Guangtong's professional customization capabilities and after-sales maintenance work, and look forward to future cooperation.
