Candle Filter Elements are groups of metal pleated filter elements fixed with candle holders to work as an candle-like filtration unit. Porous metal filters for high-temperature, high pressure polymer processing applications. Designed to remove the impurities ( such as titanium dioxide, gels and other solid residues ) of the polymer melt in chemical fiber, textile and plastics industries. Suitable for monomer, pre-polymer or polymer filter systems.Woven metal Screen Pleated Candle Elements
Polymer Melt Candle Filter Elements with Multi-Pleated Layers and Extended Filtration Area.
Pleated filter elements have one apparent advantage over cylindrical filter elements: Over three to four times of the extended filtration areas. This means lower differential pressures, greater dirt-holding capacity and longer on-stream life, and saving of cost in long term uses. Though pleated candle filter elements cost higher than cylindrical filter elements due to the material cost, processing cost, they are still popularly used in polymer melt processing.
Two main filter materials for Pleated Elements:
1. Stainless steel sintered fiber felt
Stainless steel sintered fiber is a filter material made of stainless steel fibers random arranged and sintered in high temperature. The sintered web is supported with two or more layers of woven wire cloth, and pleated and finished with high-precision welding. Polymer pleated filter cartridge made of sintered metal fiber has the advantages of high porosity, good air permeability, high dirt holding capacity, can be used repeatedly, etc.
2. Stainless steel woven wire mesh.
Stainless steel wire mesh is made of stainless steel wire by weaving. The stainless steel woven wire meshes with coarse opening and fine opening are arranged in different layers, then pleated. It has the advantages of smoth pore, easy to wash ,resistant to high temperature & corrosion, firm structure, long working life etc.
Polymer Filter with Woven Mesh and Perforated Support TubePleated candle filters are mainly used in high molecular polymer, water and oil treatment, high temperature medicine filtration etc.
