Stainless Steel Filter Cartridges | Filter Elements

What is the stainless steel filter cartridges? Stainless steel filter cartridges is a filter made up of some layers of stainless steel 304/316 mesh and have protective stainless steel cartridge filter housing. The middle mesh layer determines the filtration efficiency and is overlaid with outer and inner layers of coarser mesh to offer support and protection. These metal filter elements can be designed as plain cylindrical or pleated configurations to increase the filtration area. Working principle: The stainless steel filter cartridge will trap or block the impurities( such as chemical impurities and physical impurities.) in the fluid when the fluid flows through.

Wide Applications: Catalyst Recovery In Petrochemical / Chemical Industries; Oil Filter; Gas Filter; Hot Gas Filtration; fuel filter; Polymer Filtration; Hydraulic Oil Filtration; Cross Flow Filtration; Medical devices; Analytical Devices; Aerosol Application; R.O. Pre Filtration; Gas-Liquid Separation, etc.

Saifilter stainless steel filter manufacturer produces cleanable stainless steel filter elements based on the industrial standard and customer's customization. Our stainless steel filter cartridges can be wrought into tubes, cartridges or disks, flat cylinder shape, pleated or according to your diversification design requirements. The filter mediums can be sintered wire mesh, sintered metal fiber, and stainless steel woven mesh.

A good amount of application for the Stainless Steel Filter is on an industrial basis; they involve significantly high temperatures and pressure systems.

Gearbox and Bearing Lube Oil Filtration

The systemic design of a vehicle's gearbox makes oil and lubricants a significant requirement, which helps to relieve friction in the moving parts.

A specific function of the Stainless Steel Filter Cartridge is to enable proper filtration of impurities in the oil or lubricants that can cause damage to the vehicle.

Catalyst Recovery

Many chemical reactions occur in the presence of solid catalysts. Powder catalysts based on precious metals (such as platinum) or zinc complexes are often used. These catalysts are usually highly specialized and therefore very expensive.

Cross-flow filtration can continuously recover the catalyst from the reaction mixture and then return to the process flow. This means long-term cost savings. Likewise, filter elements made of stainless steel or special alloys have a wide range of chemical resistance and are therefore best suited for this task.

Fluidized bed combustion (FBC)

This is a method of combustion effective in burning solid fuels.

Because of the sensitivity of the system, impurities can alter the entire chemical process. The stainless steel filter is effective in removing pollutants from the system.

Polymer Production

Polymer products such as injection molded parts, films or fibers will use polymer melts. According to their chemical structure and degree of polymerization, their viscosity is different, which is related to temperature and determines rheology.

The stainless steel filter element ensures that no particles or gels enter the processing machine and avoids defects in the finished product.

Water Treatment

Water is easily contaminated by dust, algae, chemicals, decaying sediments, organic matter, and rust. By allowing water to pass through the stainless steel filter cartridges, we can filter the water and make it free from contamination.

Seal Protection

Because of how constantly the seal of industrial tools like refiners and pumps are in rotation, a dent of impurities may lead to a total collapse of the system. The stainless steel filter cartridge helps to rid the system of any impurity capable of causing significant damage to the system.

Hot Gases

Stainless steel filter cartridge is very suitable for dust removal of hot exhaust gas. As an example of use is the processing of biomass gasification products. According to the quality of the fuel used, the gas contains condensed water and dust. The use of dust filter elements is based on polymer filter media. The exhaust gas must be cooled before filtering so that the heat exchanger installed here can separate some corrosive particles.

The use of high-temperature resistant stainless steel filter elements will ensure that dust is removed from the hot exhaust gas and protect downstream components.

  • High strength, High hypertonicity, lower original pressure drop; Great corrosion resistance, heat resistance, pressure resistance, and wear resistance
  • Stainless steel filter cartridges can be back washed & reused since there is no media migration
  • Corrosion Resistance to make it a suitable instrument that does not contaminate the passing fluid.
  • Suitable for harsh operation environments, including corrosivity conditions, high temperatures, or the place with poor system high pressure, and excellent product compatibility.

The stainless steel filter cartridge is useful for variants of experiments with large filtering areas and high filtration efficiency. To enable the filter cartridge to work at optimal conditions, you must periodically carry out specific methods of cleaning. Some of these methods include:

  • Ultrasonic Cleaning Method

In this cleaning method, some vacuum bubbles are generated via a cleaning liquid, usually the longitudinal wave. The impact force of the pressure drives the cleaning process of the stainless steel filter cartridge. It does this by exacting pressure on the bubbles until they burst.

  •  Reverse-water Cleaning Method

In this cleaning method, which is sometimes referred to as the backwashing method, an inert gas, usually nitrogen, backwashes the stainless steel filter in its opposite direction.

  • Solution Cleaning Method

In the solution cleaning method, the stainless steel filter cartridge is soaked for about an hour in a 5 percent nitric acid solution or sodium hydroxide solution.  You can extend or shorten the soaking time base on the level of contamination and then dry it naturally with clean air.

Precautions:

  • You can clean some of the stainless steel filter element directly in the detergent solution but avoid soaking it for an extended period. Also, consider cleaning the filter layers.
  • Paper materials for filter layers cannot be cleaned with water.
  • The cleaning direction and the filtration direction are complete opposites.
  • Although stainless steel filter has an immense solid structure, using hard objects to clean the filter layers can cause wear.
  • Dissuade from using powerful acid or alkali when cleaning the stainless steel filter.

When you want to buy stainless steel filter elements for your industrial filtration needs. How to choose a reliable supplier? Here are several reasons for choosing Saifilter stainless steel filter manufacturer:

Saifilter Stainless Steel Filter Elements Offer Various Assembly Technology

The production costs of wire mesh filters using glued structures technology are lower, but it can offer enough strength to many high-pressure applications. The epoxy resin bonding structure is the ideal choice for most fluid applications.

The production of stainless filter elements using hemming and welding technology can overcome the temperature and compatibility limitations of cellulose or synthetic fiber boxes. When the application of extreme temperature ranges breaks the traditional glue-structured elements, we anneal all sintered metal filter elements to minimize the possibility of element failure due to a combined influence of intergranular corrosion and high pressure.

All the components of the sintered mesh filter are made of 304 or 316 stainless steel. These components can be used in a higher temperature environment, and are suitable for harsh environmental applications related to extreme temperature, high pressure, and corrosive fluid.

Each component has been permanently marked by laser for easy identification and retrospect.
