Product Description
Pleated sintered felt filter element, pleated sintered felt filter element, metal pleated filter element
The main filter material of the pleated sintered felt filter element is sintered felt made of stainless steel fiber. Sintered felt made of stainless fiber is used as the core filter layer. Sintered stainless fiber felt is made by sintering metal fibers. Metal fibers are produced in the following manner: a number of metal wires are bundled and simultaneously drawn to the required fiber diameter, then bundled into a bundle of equal weight and standard diameter, cut, and then formed into a loose felt using a suitable method. Sintered felt is produced by sequentially laying several layers of loose felt from fibers of different diameters on top of each other, resulting in the formation of a layer of accumulated fibers of a certain thickness; the fibers intersect with each other, forming a three-dimensional porous structure, after which high-temperature vacuum sintering and subsequent rolling are carried out to obtain the finished sintered felt.
Due to the fact that the sintered felt is uniformly formed in a three-dimensional labyrinthine manner, pores of optimal size with uniform distribution are formed between the fibers; The porosity can reach more than 85%, which is twice the porosity of sintered metal powder filter elements. The stainless fiber sintered felt filter element uses a multi-layer pleated design to achieve maximum filtration area. The basic structure includes: outer protective frame, inner protective frame, precision filter layer, inner support layer and inner support frame. Due to its pleated shape, it is also called pleated filter element.
