304 Stainless Steel Sintered Mesh Filter Cartridge with G1/2 Male Thread

Product Description

The TOPEP 304 stainless steel sintered mesh filter cartridge is a compact reusable metal filter element designed for industrial liquid, gas and process filtration applications. Manufactured from stainless steel 304 sintered mesh, the filter provides a rigid and durable filtration structure compared with conventional disposable polymer or paper filter media.

Unlike disposable filter media, stainless steel sintered mesh elements can be cleaned using suitable methods according to the application and filter construction, which can make them suitable for repeated service. Industrial sintered metal filters are also used where thermal resistance, chemical resistance and durable filtration media are required.

TOPEP can manufacture standard and customized stainless steel sintered filters according to application requirements. Customers can provide a sample, drawing, dimensions, connection type or filtration requirement for technical evaluation.

Product Features

1. Durable 304 Stainless Steel Construction

The filter is manufactured from 304 stainless steel, providing a strong metallic structure suitable for industrial filtration environments. Compared with many disposable filter media, stainless steel mesh provides higher mechanical stability and can be designed for repeated service.

2. Sintered Mesh Filtration Media

The filtration media consists of sintered stainless steel wire mesh. Multi-layer metal mesh structures can combine different mesh layers to provide filtration performance, flow distribution and mechanical support in a single rigid filter medium.

3. Reusable and Cleanable Design

One of the main advantages of metal mesh filtration is its cleanability. Depending on the process fluid and contamination type, suitable cleaning methods can allow the filter element to be reused rather than discarded after a single filtration cycle. This characteristic makes cleanable metal filters attractive for applications requiring regular maintenance and repeated filtration.

4. Rigid Cylindrical Structure

The cylindrical construction provides a stable filtration surface and helps maintain the filter shape during operation. Sintered metal mesh is known for its robust, self-supporting structure and resistance to mechanical abrasion.

5. Compact G1/2 Male Thread Connection

The G1/2 male threaded connection provides a compact installation configuration for compatible filter housings, manifolds and filtration assemblies. The connection can also be customized when the standard configuration does not match the customer's equipment.

6. Suitable for Demanding Filtration Applications

Metallic filter media can be selected for applications where mechanical strength, cleanability, temperature resistance or chemical compatibility are important. Sintered metal filters are used across liquid, gas, steam and industrial process filtration applications.

Filter Structure

Stainless Steel Sintered Mesh Filter, also called Metal Mesh Sintered Filter, Alloy Mesh Filter, Sintered Layer Filter, along with porous powder sintered filter element, fiberglass sintered filter element, and PP/PE sintered filter element, all belong to the broad category of sintered filter elements.

The sintering mesh filter usually has five layers of stainless steel woven wire mesh, including one protective layer, one filter layer, one separating layer, and two supporting layers. Can also add a skeleton layer according to the using conditions sometimes.

Applications of Stainless Steel Sintered Mesh Filter Elements

Stainless steel sintered mesh filter elements are widely used in industrial filtration systems where high durability, precision filtration and long service life are required.

Due to their excellent mechanical properties and chemical resistance, these filters are commonly selected for applications involving liquid filtration, gas filtration, hydraulic systems, chemical processing equipment and industrial machinery.

The reusable design makes them especially valuable in industries where reducing downtime and maintenance costs is important. By selecting the appropriate pore size, material and structure, the filter element can provide efficient filtration performance for different operating environments.

For customers who need a customized solution, TOPEP can evaluate the application conditions and recommend a suitable filter design.

Different Kinds Of Connection Can Be Custom

Cleaning Methods of Sintered Mesh Filter

The stainless steel sintered filter elements require standardized cleaning and proper daily maintenance during regular use to extend their service life.

Physical Methods

► Backwashing--Use clean water or compressed air to flush out impurities from the pores and surface of the filter element by introducing it from the outlet end in the opposite direction. Suitable for removing surface particles, sediment, and dust-like impurities. The pressure is at a range of 0.3 - 0.6MPa, the flow rate should be large enough to produce a strong flushing effect, but not so large as to damage the filter element.

► Ultrasonic Cleaning--Place the filter element into an ultrasonic cleaning tank filled with cleaning solution. The high-frequency vibrations of the ultrasound will dislodge impurities from the surface and interior of the filter element. The ultrasonic frequency is typically between 20 and 80 kHz, and the cleaning time is generally 15 to 30 minutes. This method is suitable for cleaning fine particles, oil sludge, and gelatinous impurities from micropores.

► Mechanical Brushing--For filter elements with stubborn stains or large particulate impurities on their surface, you can gently brush the surface of the filter element with a soft brush after backwashing or ultrasonic cleaning. However, be careful not to apply too much force when brushing, as this may damage the filter element's mesh structure.

Chemical Methods

► Acid Cleaning--When the filter element surface contains metal oxides or scale-like impurities such as calcium and magnesium, acid cleaning can be used. Commonly used acid cleaning agents include hydrochloric acid, nitric acid, and citric acid. The acid is prepared into a solution of a certain concentration, and the filter element is immersed in the acid cleaning solution for a period of time, and then rinsed thoroughly with clean water.

► Alkaline cleaning--When the filter element is contaminated with oil or organic matter, alkaline cleaning is an effective cleaning method. Alkaline solutions such as sodium hydroxide or sodium carbonate can be used, typically at a concentration of 5% to 15%. The filter element is immersed in the alkaline solution and heated appropriately for 1 to 3 hours, and then rinsed with clean water until neutral.

► Surfactant cleaning--For organic contamination, cleaning can be combined with the use of surfactants or enzymes (high concentrations of citric acid can be used in the food and beverage industry).

High-temperature Roasting

When organic matter is severely carbonized, the residue can be removed by high-temperature baking. This method is suitable for high-temperature operating conditions and high-temperature resistant filter elements. The baking temperature is generally ≤450℃, followed by a period of heat preservation and then natural cooling. It should be noted that not all sintered mesh filter elements are suitable for this method; the suitability depends on the material.

FAQ

Q1: What is the difference between a stainless steel sintered mesh filter and a normal wire mesh filter?

A: Stainless steel sintered mesh filters are manufactured by bonding multiple layers of mesh through a sintering process. This creates a stronger structure with better pressure resistance, more uniform pores and longer service life compared with standard wire mesh filters.

Q2: Can this filter element be cleaned and reused?

A: Yes. Stainless steel sintered mesh filter elements are reusable. Proper cleaning methods such as backwashing, ultrasonic cleaning or chemical cleaning can restore filtration performance and extend service life.

Q3: Can TOPEP manufacture customized sizes?

A: Yes. TOPEP provides OEM and ODM services. Dimensions, filtration accuracy, connection types and special structures can be customized according to customer requirements.

Q4: Which stainless steel material is available?

A: Common materials include 304 and 316L stainless steel. The suitable material can be selected according to corrosion resistance requirements and working conditions.

Q5: How can I choose the correct sintered mesh filter?

A: Customers can provide information including filter size, filtration medium, operating temperature, pressure and filtration accuracy. Our engineers will recommend a suitable solution.
