China Suppliers Factory for Polymer Candle Filter Elements SUS 304 - High-Performance Filtration Solutions
Description
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)
What is a polymer pleated candle filter element used for?
A polymer pleated candle filter element is used in extrusion lines to remove impurities from polymer melts before the spinning process. It ensures the melt is clean and consistent, resulting in high-quality continuous filaments or staple fibers.
What filter media are available for pleated candle filters?
The two primary filter media are stainless steel wire mesh and stainless steel sintered fiber. Wire mesh offers smooth pores and easy cleaning, while sintered fiber provides high porosity, excellent dirt holding capacity, and strong regeneration ability.
What is the maximum operating temperature for these filter elements?
The pleated candle filter elements can withstand a working temperature of up to 350°C, making them suitable for high-temperature polymer melt filtration applications.
What filtration ratings are available for polymer candle filters?
The filtration rating ranges from 1 to 200 microns, covering a wide spectrum of filtration needs from fine to coarse filtration across various industrial applications.
How do you clean and maintain industrial pleated filter cores?
Most industrial filter cores need to be removed from their housing, then sterilized and washed. Some systems support backwashing or CIP (Clean-In-Place) designs. After cleaning, the filters should be dried and stored in sealed or vacuum-packed conditions to prevent contamination.
Which industries commonly use polymer pleated candle filter elements?
These filter elements are widely used across petrochemical, metallurgy, textile, electronics, pharmaceutical, food and beverage, automobile manufacturing, thermal power, and nuclear power industries — anywhere that reliable high-temperature or high-viscosity filtration is required.
