The sintered metal fiber filter cartridge is made by sintering and bonding randomly laid 361L metal fibers to form a uniform high-porosity (up to 85%) filter medium and high flow rate (up to 20 times that of other media types). It has a significant low pressure drop, high permeability and good dirt retention ability. These filter elements are the same as those used in our hot gas filtration system components, which are often used in challenging high temperature applications.
The metal felt media can provide absolute particle retention, longer flow time and high dust holding capacity of the filter element below 60 microns. Although more expensive, it usually has obvious advantages over metal wire mesh and non-metallic fibers. Its high temperature, high pressure, corrosion resistance and repeated cleaning make it very economical in harsh environments.
The sintered metal fiber filter cartridge has an operating temperature range of -269°C (-452°F) to 1000°C (1832°F) and can withstand a typical maximum pressure difference (normal flow) direction up to 15bar (218psi). Various micron grades from 5µm to 60µm (nominal) are available.
Because the metal fiber formula can meet specific application requirements and inherent durability, the sintered metal fiber filter can be cleaned on site without interrupting the process flow. By minimizing downtime, this will provide an economical final process.
