Sintered metal powder filters are a powerful filtration solution made by bonding metal particles through a high-temperature process. These tough filters are made by fusing metal powder at high temperatures, creating a strong, porous structure. Sintered powder filters can handle both liquids and gases, making them suitable for various applications like filtration, flow control, and ventilation. They can also be used as flame arrestors and silencers. Compared to other filter materials, sintered filters boast superior mechanical strength and can withstand high pressure and continuous use as their thickness can be tailored easily.
The use of stainless steel/titanium/nickel-based alloy/intermetallic powder in their construction provides exceptional resistance to corrosive chemicals, ensuring reliable performance in harsh environments. Cold isostatic pressing and sintering creates a highly porous and stable filter media. This translates to long-lasting performance and efficient filtration. These filter cartridges are simple to install and replace within their filter housing. Sintered filters can often be effectively cleaned or backwashed, extending their service life and reducing waste compared to disposable filter options. They are available in various materials, including 316L stainless steel, Hastelloy C-22/C276, amongst others.
What is a Sintered Metal Filter?
A sintered metal filter is a filter engineered using the sintering technology. Sintered metal filters designed with perfect combination of metal membrane materials, pore structure, composition, and pressure strength last longer and filter consistently over the time. Variants of such filters offer compatibility and are designed for various harsh operation environments like high pressure, high temperature, corrosive chemicals, to name a few.
What is Sintering?

Sintering is a technology that fuses particles together by using heat and pressure without melting the metals. Various metals are sintered to engineer filter equipment, elements and different type of cartridges with a variety of pore size structure and composition.
Why Sintered Metal Filters?
Sintered metal filters are robust and exhibit excellent performance for separation of particulate matter from either liquid or gas process streams. The filter media is fabricated from metal power or fiber and sintered to form filter elements. These filter elements can withstand higher temperature as compared to other filter elements. Along with high temperature resistance, corrosion is also other criteria where sintered elements prove superior. Additionally, the cost of ownership of sintered filter systems is considerably low as they can be cleaned via &#;blowback cleaning&#; multiple times and reused with the same filtration efficiency.
The sintered filter systems and elements are critical in achieving effective particulate removal to protect equipment, meet environmental regulations and achieve successful cost-effective filtration operations.
