Types Of Sintered Filter Disc
FiltEdge has over a hundred types of sintered filter discs, with filter discs of different sizes, accuracies, materials, and structures to meet your various process requirements.
The Sintered filter sheet is made of 304, 316, and 316L stainless steel materials, which combine cost-effectiveness and high performance.
In addition to stainless steel materials, there are high-performance metals such as nickel alloys and titanium/titanium alloys that can handle higher temperatures and corrosive harsh working conditions for you.
Porous powder-sintered structure， The precision can reach 0.1 microns, which can deeply filter fine impurities for you.
Multi layer woven metal mesh is laminated and sintered together, which is sturdy, not easily deformed, and easy to clean, suitable for working conditions that can withstand large pressure differentials or backwashing.
Advantages Of Sintered Filter Disc
The 6 major advantages of FiltEdge’s Sinteredfilter disc can accurately solve pain points in production and operation, and stabilize the quality of each batch of products for you.
FiltEdge’s sintering technology can achieve consistent narrow pore size distribution for each batch, achieving quantifiable interception efficiency and providing you with quantifiable and traceable filtering results to ensure your product yield.
The Sintered filter disc can withstand positive pressure differentials of up to 0.6 MPa or more, as well as frequent backwashing, achieving no deformation, rupture, or medium detachment, thus eliminating secondary pollution in production.
Excellent pore size, porosity, and filtration area ensure long-term stable pressure drop operation of the sintered filter disc. Stable circulation and predictable cleaning cycles help you avoid unplanned downtime.
FiltEdge can provide you with various metal materials such as stainless steel, nickel alloy, titanium alloy, etc., to cope with acidic, alkaline, chloride containing ions, organic solvents and other corrosive media.
Support various cleaning and regeneration methods such as gas-liquid mixing backwash, ultrasonic cleaning, chemical cleaning, and high-temperature calcination. The flow recovery rate after cleaning can reach over 85%, reducing the long-term cost of disposable filter materials for you.
The metal material of the sintered filter disc can be used in a working environment of 600-700 ℃ for a long time, which can maintain a more stable structure and filtration accuracy than plastic filter materials, providing a reliable barrier for your process.

Okay. FiltEdge supports you to customize your Sinteredfilter disc based on your drawing. You only need to provide CAD or PDF drawings of the external dimensions, scheme method, thickness, accuracy, and material requirements. Our engineers can provide you with a feasible plan.
To better customize the Sintered filter disc, we suggest that you provide the following information:
- Operating conditions: filter media (gas/liquid/melt), operating temperature, system pressure, flow requirements
- Filtration requirements: filtration accuracy, maximum allowable pressure drop, inlet and outlet particle concentration
- Equipment interface: filter disc installation size, sealing method (such as flange/clamp/welding), sealing surface requirements.
- Cleaning method: Is backwashing used? Cleaning frequency? Have you come into contact with chemical cleaning agents?
- Certification report: Is FDA/GMP compliance required? Do I need a material certificate? And do you need any other compliance documents that comply with your local/sales market?
The more complete the information you provide, the more matching the solution we will provide for you.
Of course. We can usually provide you with 3-5 pieces of sintered filter disc samples for working condition verification. And it will record material reports and precision testing data of the samples to prepare for mass production in the later stage, ensuring that the same process standards and testing procedures are followed for bulk production, and providing you with bulk products of the same quality as the samples.
