What are Sinter Metal Filters used for?

All-metal sintered filters are resilient to parts-corrosive conditions and can withstand high temperatures. They allow a selected fluid to travel through a sintered mass to capture suspended particulates. The powder compaction process varies, so the filter permeability can be tailored to the selected fluid. The bore pitch can range from 10 to 50 microns. A standard screening solution will feel the strain when high-temperature gases are forced down a channel sealed at the top.

High filtration efficiency

Sinter Metal Filters is manufactured by bonding particles in powder form together and sintering them at temperatures below the melting point. This process involves three key steps: the sintering process, the pore size of the sintered metal, and the pressure drop during the flow of the filter material. The sintered metal filter elements can be manufactured from a variety of materials, including nickel, titanium, chromium, and more.

The sinter metal fiber medium provides good permeability and low pressure drop. These characteristics result in a low total cost of ownership, and low operating costs. The porous structure also provides a high level of clean ability. As a result, this type of filter is suitable for industrial use. For further research, sintered metal filters can help reduce emissions into the atmosphere and protect downstream equipment. In a future paper, the results of the experiment will be discussed.

Low pressure drop

Sinter Metal Filters is used in the production of high-quality air filtration media. These filters are composed of metal fibers that are randomly laid, and then sinter bonded to produce a uniform, high-porosity filter medium. These filters demonstrate low pressure drop and excellent dirt holding capacity. Furthermore, they can be cleaned in situ, reducing the time and effort required to clean them. They are also suitable for aggressive air filtration applications.

The filtration efficiency of sintered metal filters is determined by the micron rating of the filter element. The micron rating is dependent on the process used to produce the filter element. During the manufacturing process, metal spheres are pressed together and bonded with each other. A sintered metal filter’s micron rating is described by the microns, it can withstand. The process is complicated and requires precise heat, pressure, and specialized machinery. The cost can run into the six figures.

Chemical resistance

The chemical resistance of Sinter Metal Filters depends on its structure. The porous metal media used in this type of filter are designed with high rigidity and good resistance to acid, alkali, and corrosion. Their high filtration accuracy makes them a versatile choice for many applications. Furthermore, their simple design and reliability allow them to be easily cleaned and reused. In addition, sintered metal filters are available in different shapes.

The fabrication of these filters can be done in several different metal alloys, each with its own specific properties. Most of these porous metal filters are made of nickel-based alloys, such as Inconel 400 and Hastelloy. Other alloys used for these filters include GKN Sinter Metals and Monel 400. They are also made of FeCrAl. The nickel-based materials used in these filters have a high level of corrosion resistance, making them ideal for applications where chemical resistance is paramount.

Noise reduction

Sinter Metal Filters (SMF) are designed to reduce noise generated by industrial processes by trapping airborne impurities and converting them into non-resonant gas. They are made of stainless steel or bronze and have a high porosity level (25-60%). These filters are manufactured using powder metallurgy technology, which involves molding and sintering metal powders to form preforms. The resulting metals are then cooled, tempered, and shaped into the shape desired by the manufacturer.

The most common application for Sinter Metal Filters is noise reduction. They are used in air solenoids and air tools and are highly effective in reducing noise levels. Their design is based on the science of metal porous materials. Sinter Metal Filters is durable and withstands parts corrosion and soaring temperatures. They are also available in multiple materials, including copper, nickel, and alloys. The sintering process can create filters with a pore pitch of ten to fifty microns.

Powder fluidization

Sinter Metal Filters is highly efficient air filtration systems. They contain both filter and catalyst reaction portions. The filter part traps the dust and the catalyst reaction part undergoes catalytic reactions with the gas. This results in the removal of the harmful substances in the gas and allows the fluid to flow through the system. This high-performance system is also designed to be economical and requires minimal maintenance. There are many uses for a Sinter Metal Filter.


Sinter Metal Filters is widely used in powder fluidization processes because they are versatile and easy to manufacture. They can be fabricated into various shapes, including flat sheets, fluidizing elements, and complex conical assemblies. In addition to being versatile, Sinter metal filters are lightweight and can be used intermittently at temperatures ranging from 210°F to 230°F. They are available in both a surface and depth filter and have self-sealing properties.
