Sintered Porous Plastic Filters
Saifilter industrial filter manufacturer provides a complete choice of sintered porous plastic filters, candles, rods, discs, sheets, and custom-designed products. The sintered porous plastics have good chemical compatibility, excellent filtration efficiency of subtle stable particles， and outstanding mobility of liquid and gas. Most of the materials used in porous plastics can be any thermo-plasticity polymer, but polyethylene or polypropylene are more commonly used.
These plastic porous materials can produce multiple cellular structures of interconnection and aperture ranges by controlling granularity distribution and accurate circulating temperature during the sintered procedure. The porous plastics consist of thousands of tiny connecting holes or open spaces. These pore structures are designed and controlled to adapt to the application in all fields, and it is an ideal material for wicking and fluid transfer. It can manufacture different components according to your application, such as muffling, pneumatic filter elements, porous plastic sheets, PE candle filters, diffusion, or gaseous emission.
The porous plastics reserve the physical property of intercepting its corresponding sold particle. The unique “zigzag filtration path” combines the characteristics of surface and deep porous plastic filters to produce high filtration efficiency. The porous plastic has outstanding elasticity, airtightness, and increased physical strength. It is lightweight, providing firm and efficiently handled components that can realize a filtration rate of 99.8%, and the temperature tolerance is up to 110℃(230F°). According to all kinds of applications, various products are provided to meet your different needs.
Pneumatic Muffler
A porous pneumatic silencer design provides the best balance among the acceptable backpressures in the noise reduction and air-operated system, effectively reducing the noise of pneumatic equipment. Compared with a metal silencer, it has more advantages.
Porous plastic air silencer design has significantly lower weight and the capacity of corrosion resistance and filtering particles and aerosol, which brings higher durability, installation rate, and cost-effectiveness for our partners. Our air silencer is designed using a firm, integrated screwed nipple to ensure the easy installment of pneumatic equipment.

Pneumatic Filter Element
It can provide needed gas for cleaning the air and regulating air pressure to the gas source of pneumatic equipment. Our pneumatic porous plastic filter design is mainly applied for the coordination use of pneumatic controllers and lubricators. Traditional sintered metal filters can be completely replaced by it.
These sintered plastic filters are specially designed to provide particle filtration, a perfect match of airflow and backpressure performance. At the same time, they meet both strength and aesthetics requirements.
- Meet your filtration requirements – The design is optimized to meet the filtration, airflow, and pressure drop requirements.
- Low costs – The sintered polymer filter is more cost-effective than the sintered metal filter.
- Improve the service life of machines –The design is optimized for the reliability, efficiency, and service life of the pneumatic machinery.
- It is used in conjunction with a regulator and lubricator (FRL units) to offer clean and adjusted compressed air or gas.
- The stable strength can realize the longest service life and effectiveness.
- It is more cost-effective than the traditional sintered metal filter.
- Advanced porous plastic material(PE, PP).
- Constructible shapes: cylinder, cone, etc.
- The aperture of 3-200 microns
- 1-8"OD
- The length can be up to 40"

Applications
Liquid filtration: The porosity can reserve the solid particles contained in liquid and gaseous fluid, moreover, the liquid phase and solid phase can be separated. The applied areas include automobile, ship, aviation, railway industrial machinery, etc.
Flow control: The isotropy and uniform porosity allow the circulating liquid herein to have constant flow at the exit of porous parts. The typical applications are heat exchangers, medical gas, scuba diving industrial gas, etc.
Fluidization: The air circulation of porous components causes the same pressure distribution of the outlet flow at all points, allowing controlled handling of powder products. The applications of this property: are cement transportation, flour, aluminum oxide, ash, powered link, etc.
Moisture-proof: The porosity can maintain and control the moisture contained in the gas passing through it.
Frame protection: There are porous components in front of the frame, so the accident can be avoided when the frame returns. The typical applications include gas burners, heaters, and welding equipment, etc.
Porous Plastic Fluidizing Plate and Sheet
High molecular weight polyethylene material is used to produce high-quality porous plastic sheets, which are also named fluidized bedplates. The product can provide a homogeneous air distribution of material diffusion, air inflation, and fluidization.
Every side of the porous plastic sheet of Saifilter is upward, and it is easy to install. Conventional metal processing devices or standard hand tools can be used to modify. Standard RTV organosilicon or equivalent is used to seal the sheets in place. The full open network is used by these steady chemical inertness panels for effective filtration of the “zigzag path.” There are many optional apertures of these panels.
