Filtration is an essential process in many industries, including food and beverage, pharmaceuticals, chemicals, and oil and gas. The filtration process removes impurities, contaminants, and other unwanted particles from liquids and gases, ensuring that the end product is safe and of high quality.
There are various types of filters available in the market, but metal filter cartridges have gained popularity due to their durability, high efficiency, and versatility. In this blog, we will take an in-depth understanding of metal filter cartridges.
What are Metal Filter Cartridges?
Metal filter cartridges, commonly known as stainless steel filter cartridges, are essential components for industrial filtration applications. A metal filter cartridge is specifically made to supply clean fluid for downstream equipment and safeguard it from wear and tear in order to achieve process purification and requirements.
Metal filter cartridges can be constructed with a variety of materials, including standard 304 or 316L stainless steel, as well as special alloys like titanium and nickel. Additionally, they can be sealed using various materials such as NBR, EPDM, silicone, Viton, and others.
These filters are available in various sizes and configurations, including pleated, cylindrical, and disc-shaped. They are designed to fit into standard filter housings and can be used for both liquid and gas filtration.
How do metal filter cartridges work?
Metal filter cartridges work by trapping impurities and contaminants within their porous structure. The filter media can be made from woven metal wire mesh, sintered metal powder, or metal fibers. The size of the filter pores determines the level of filtration, with smaller pores providing finer filtration. Metal filter cartridges can also be designed with multiple layers of different pore sizes to achieve a specific level of filtration.
Metal filter cartridges are primarily utilized to eliminate harmful impurities of different sizes, ranging from coarse to fine, from water, oil, steam, or air/gas mediums. The micron rating of metal filter cartridges can vary between 0.1 to 200 microns. These filters can function in both outside-to-inside and inside-to-outside flow patterns, as they retain dirt particles on their surface while allowing clean fluid to flow out.
Benefits of Metal Filter Cartridges
Durability
Metal filter cartridges are highly durable and can withstand harsh conditions, making them ideal for industrial applications. They are resistant to corrosion, high temperatures, and pressure, ensuring that they last longer than other types of filters.
High Efficiency
Metal filter cartridges are highly efficient in removing impurities and contaminants from fluids. They have a high dirt-holding capacity, which means that they can hold a large amount of dirt before needing to be replaced. This makes them ideal for applications where a high level of filtration is required.
Versatility
Metal filter cartridges are versatile and can be used in a wide range of applications. They are suitable for filtering liquids such as water, oil, and chemicals, as well as gases such as air and natural gas. They can also be used in different industries, including food and beverage, pharmaceuticals, and petrochemicals.
Easy to Clean
Metal filter cartridges are easy to clean and can be reused multiple times. They can be cleaned using different methods, including backwashing, ultrasonic cleaning, and chemical cleaning. This makes them a cost-effective solution for filtration needs.
Types of metal filter cartridges
Brother Filtration offers a wide range of metal filter cartridges designed to meet various filtration needs. The four main types of metal filter cartridges we produce are Metalman PSF filter cartridges, Metalman PSM/CSM filter cartridges, Metalman Titanium filter cartridges, and Metalman CSSM filter cartridges. Each type has unique properties that make them suitable for different industrial applications.
Metalman PSF filter cartridges
Metalman stainless steel felt cartridges utilize folding and forming to create a large filtration area, resulting in an absolute filtration accuracy. The stainless steel fiber sintered felt used in these cartridges is a porous depth type filter material that is created by sintering stainless steel fibers at high temperatures. This process results in a highly durable and efficient filter material that can effectively remove impurities from fluids such as water, oil, and gas.
The unique structure of the stainless steel fiber sintered felt allows for high dirt holding capacity, low pressure drop, and long service life. Metalman’s stainless steel felt cartridges are an excellent choice for applications that require high filtration efficiency and durability.
Metalman PSM/CSM filter cartridges
The Metalman pleated stainless steel mesh cartridge is constructed using woven stainless steel mesh that can be shaped into both pleated and cylindrical structures. The pleated design of this cartridge provides a larger filtration area, resulting in improved performance in terms of flow rate and lifespan. This makes it an ideal choice for a wide range of applications.
The woven stainless steel mesh used in the construction of this cartridge is resistant to corrosion and can effectively remove impurities from fluids such as water, oil, and gas. The pleated stainless steel mesh cartridge is one of the most commonly used stainless steel cartridges due to its versatility, efficiency, and durability.
Metalman Titanium filter cartridges
The Metalman Titanium Cartridge Filter (TCF) is a highly efficient solid-liquid separation cartridge that is composed of over 99.4% high purity titanium structure. Its extensive chemical compatibility makes it a great option for the filtering of most liquids. The unique properties of the titanium structure used in the TCF make it highly durable, corrosion-resistant, and capable of withstanding harsh environments.
The TCF is particularly effective in separating rigid particles from low viscosity liquids. For optimal results, it is recommended to use the TCF in combination with a titanium rod filter. With its superior solid-liquid separation performance, the Metalman TCF is an ideal choice for various applications in the chemical, pharmaceutical, and food and beverage industries.
Metalman CSSM filter cartridges
The Metalman CSSM filter cartridge is made of sintering multiple layers of 316 or 304 stainless steel mesh, resulting in a highly durable and corrosion-resistant filter. The high dirt-holding capacity of the CSSM filter cartridge is a noteworthy feature, making it an excellent choice for applications that require efficient filtration
This stainless steel cartridge is known for its exceptional back flushing effect, making it an ideal choice for solid-liquid separation of liquids with rigid particles. This filter cartridge is particularly effective in back flushing rigid particles, resulting in an even better back flushing effect.
Conclusion
Metal filter cartridges are an essential component of many industrial processes, like Chemical Processing, Food and beverage, and Oil and gas, providing reliable and efficient filtration performance. Metal filter cartridges also have features of high temperature and high pressure and corrosive chemicals.
By combining cutting-edge technology with premium materials, Brother Filtration produces high-quality metal filter cartridges.
