In addition, the sintered felt type of candle filter has good breathability, large pollution capacity, long service life, uniform mesh size, high strength, good processability, and convenient cleaning. This type of filter can not only be used on self-designed filters, but also as a substitute for imported similar filters to meet the needs of highly automated unmanned cabins and large lubrication equipment. At the same time, its appearance is exquisite, all using a metal mesh structure, with a long service life, lightweight and easy to replace.

Candle type filter cartridges are mainly used for filtering high temperature, high pressure, and high viscosity polymer and polyester melts. The upper and lower covers are made of stainless steel material (316L) to ensure its corrosion resistance, while the filtering medium is made of stainless steel fiber sintered felt and stainless steel wire woven mesh folded and corrugated, with a small external size and a large filtering area, which can be repeatedly cleaned and used.
