Porous Sintered Metal Filter | Metallic and Cleanable Filters

Porous Sintered Metal Filter is a depth-based sintered products element. It removes the particle through capturing particles and placing them in the filter medium structure. It statically presses the metal powder in the flexible molds with specific shapes. The size of the removal particle is adjusted by changing the compaction pressure or/and the particle size of the powder. The next step is sintering, which is conducted at the temperature below the melting point through the diffusion bonding of powder metal particles. After sintering, the original powder particle is replaced by a fully connected sintered filter with the porous metal structure. This process control determines the micron class of the filtration medium, Also the sintered medium is always described by its porosity. The configurations of these porous metal filters are determined by the detailed requirements of your system.

The filter medium of the sintered metal filter can be all kinds of alloys, where the most common alloy is 316. Other grades of stainless steel alloys also can be used for production, such as chromium-nickel-iron alloys, Hartz alloy, and Monel alloy, etc., each of which has its specific characteristic and applied purpose. The filter elements flexibly deployed by different sizes, shapes, and components can meet the characteristics and configurations customers required.

These components are identical to those used in our industrial high temperature dust filter assemblies, which are often used in challenging applications.

Compared with other filer elements, the direct advantages of porous sintered metal filters produced by Saifilter are that they can bear higher pressure and temperature, ductility and tenacity, and the sintered metal filter can bear process shock resistance and disturbance. Our sintered products are the popular choice in many industrial filter applications because of the heat-resisting, corrosion resistance, and abrasive resistance. The provision for all kinds of cleanable all-metal filter elements can achieve the best filtration in key applications. Our sintered metal filters play a role in the liquid and gas applications at the worst temperature, pressure, and corrosion conditions.


The sintered porous metal filter elements are mostly used in the low flow system, are mainly used for gas filtration. When hydraulic oil or viscous flow goes across this filter, the pressure drop is obviously higher. It can be used at the temperature up to 580℃(1,076ºF)according to the process conditions.
Dimensions: we have both standard and customized dimensions.
Configuration: tubular, slab-like, flake-like, discal, ring-like, rod-like, cone.

To confirm the proper design according to your requirements,please prepare the following pieces of information:
●Gas/liquid flow
●The process pressure and temperature of gas/liquid
●System pressure drop
●The expected gas preservation purity and particle reservation
●Cleanliness requirements
●The density and  viscosity of the medium

The optimum allocation can be designed by the Saifilter team, and make it is suitable for your system configuration. It is an honor to be your best sintered metal filter supplier.
