Custom China SUS 304 Polymer Candle Filter Elements - Quality Suppliers & Factory for High-Viscosity Filtration Suppliers, Company
Candle filters, named for their resemblance to candles, are essential filtration elements composed of tubular structures typically made from durable stainless steel mesh or sintered mesh. Each candle features a cap at the bottom and a threaded connector at the top, designed for easy integration with corresponding filter systems. To enhance their filtration capabilities, some models incorporate an outer layer made from perforated metal sheets, expanded metal, sintered metal, or porous ceramic, providing additional support for the filter media, These candle filter elements are designed for installation within filter housings and can accommodate between 1 to 20 candles, depending on the overall filter size. Arranged vertically within the pressure vessel, they effectively filter liquids with low solid content, ensuring high productivity while facilitating easy discharge of bottom sediments, Our melt filter elements are specifically engineered for the chemical fiber industry, making them ideal for filtering polymer melts and other viscous substances. By effectively removing solid impurities such as carbonized particles and metal oxides, they significantly enhance the purity of the melt. This process ensures that downstream operations receive high-quality raw materials and that the melt filter operates effectively, As a premier supplier and factory in China, we take pride in delivering high-quality candle filters and melt filter elements that meet the rigorous demands of various industries
The melt filter element is installed in the extrusion line, where the polymer melt is forced through the filter to remove impurities. The filtered polymer melt then proceeds to the spinning process, where it is solidified into continuous filaments or staple fibers.
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.

How to Clean Industrial Filter Cores?
🏭
Industrial fine filters are widely used in industries such as pharmaceutical, chemical, ink and paint, food and beverage, automobile manufacturing, cement industry, petroleum, oil refineries, petrochemical, etc. It is important to clean these filter cartridges to ensure that they filter consistently over a long period of time.
🔧
Industrial filter cores provided by Song Phung have high dirt holding capacity, are easy to install, clean and maintain. The fine filter element is sturdy, has a solid quality core and has well-formed layers, so cleaning and installing them is very easy.
💧
Some filtration systems allow backwashing and have a CIP system design. But most have to be taken out of their shells, sterilized and washed. When not in use, these cleaned filter cartridges are dried and sealed or vacuumed to prevent contamination or wear.
Frequently Asked Questions (FAQ)
Q
What is a pleated candle filter element used for?
A pleated candle filter element is used in polymer melt filtration systems, particularly in extrusion lines. It removes impurities from the polymer melt before it proceeds to the spinning process, ensuring the quality and consistency of the final filaments or fibers.
Q
What filter media materials are available for pleated candle filters?
The main filter media options are stainless steel wire mesh and stainless steel sintered fiber. Wire mesh offers smooth pores and easy cleaning, while sintered fiber provides high porosity, strong dirt-holding capacity, and excellent regeneration ability.
Q
What is the maximum operating temperature for these filter elements?
The pleated candle filter elements can operate at temperatures up to 350℃, making them suitable for high-temperature polymer melt filtration applications in petrochemical, textile, and other demanding industries.
Q
What filtration ratings are available for polymer candle filters?
The filtration rating ranges from 1 to 200 microns, allowing customers to select the appropriate level of filtration precision depending on their specific polymer melt filtration requirements.
Q
How should industrial filter cores be cleaned and maintained?
Cleaning methods depend on the system design. Some systems support backwashing or CIP (Clean-In-Place) procedures. In most cases, the filter cores are removed from their housings, sterilized, and washed manually. After cleaning, they should be thoroughly dried and stored in sealed or vacuum-packed conditions to prevent contamination or damage.
Q
Which industries commonly use pleated candle filter elements?
Pleated candle filter elements are widely used across multiple industries including petrochemical, metallurgy, textile, electronics, pharmaceuticals, food and beverage, thermal power, and nuclear power. They are suitable for any application requiring reliable high-temperature and high-pressure polymer or fluid filtration.
