Product Description

Description

The melt filter element is installed in the extrusion line, where the polymer melt is forced through the filter to remove impurities. The candle filter element is placed inside the filter housing (housing). It is a compact device that can typically hold 1-20 candles, depending on the size of the filter. The filter element is arranged vertically in the pressure vessel to filter liquids with low solid content. The candle filter allows high productivity, easy bottom sediment discharge.

The main filter layer of Pleated Filter mainly uses two materials: stainless steel wire mesh and stainless steel Sintered fiber. Stainless steel wire mesh is woven from stainless steel wire. Its pleated filter has the characteristics of smooth pores, easy cleaning, high temperature resistance, corrosion resistance, no wire mesh falling off, and long filtration cycle. Stainless steel sintered fiber is a porous deep filter material made of stainless steel fibers sintered at high temperature. Its pleated filter has the characteristics of high porosity, good air permeability, strong dirt holding capacity, and strong regeneration ability.
