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.
