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.

Candle type filter element, or ship filter element (also known as candle type filter element), is mainly used for oil filtration. This filter element is composed of multiple filter elements and a magnetic filter element, which has the characteristics of low resistance pressure loss, high strength, repeated cleaning, and backwashing.
