Why Porous Metal Plates Remain Essential in Industrial Filtration Having spent a good chunk of my career around dusty factories and precision-controlled filter lines, I can say porous metal plates are one of those quietly powerful components that you don’t always notice — until they stop working properly. These plates, typically made of sintered metal powder or woven mesh, serve as the backbone of many filtration and diffusion systems. Oddly enough, while their principle is simple, the variety in design and application often surprises newcomers. One of the most common questions I get from engi…
