Famous China Suppliers and Factory of High-Quality Polymer Candle Filter Elements SUS 304 for Efficient Filtration Manufacturers, Company

Candle filters, named for their resemblance to candles, are essential filtration elements commonly used in various industrial applications. These tubular filters are constructed from durable stainless steel mesh or sintered mesh and feature a cap at the bottom with a threaded connector at the top, which connects seamlessly to the core end. The design often includes an outer surface made of perforated metal sheets, expanded metal, or porous ceramics to reinforce the filter media, In a typical installation, the candle filter element is housed within a filter housing, accommodating 1 to 20 candles depending on the filter's size. Positioned vertically in the pressure vessel, these filters are ideal for processing liquids with low solid content, facilitating high productivity while allowing for easy discharge of bottom sediments, Candle filters are particularly vital in the chemical fiber industry, where melt filter elements are utilized for the filtration of polymer melts and other high-viscosity substances. Their primary role is to eliminate solid impurities, such as carbonized particles and metal oxides, enhancing the purity of the melt. This ensures that downstream processes receive high-quality raw materials, thereby maintaining the smooth operation of the melt filter, As a leading factory in China, we are dedicated to providing superior candle filters and ensuring our customers have access to high-performance solutions. Our commitment to quality and reliability has made us one of the top suppliers in the industry. Explore our range of candle filters today and experience the difference for yourself

Product Description

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)

Q What materials are used in pleated candle filter elements?
Pleated candle filter elements are primarily made from two materials: stainless steel wire mesh (woven from stainless steel wire) and stainless steel sintered fiber (a porous deep filter material made by sintering stainless steel fibers at high temperature). Both are available in SUS304 and SUS316L grades.
Q What filtration ratings are available for polymer candle filters?
Our polymer candle filters are available in filtration ratings ranging from 1 to 200 microns, allowing them to be tailored to a wide variety of polymer melt filtration applications and industry requirements.
Q What is the maximum working temperature for these candle filter elements?
The candle filter elements are rated for a maximum working temperature of 350°C (≤350℃), making them suitable for high-temperature polymer melt filtration processes in extrusion and spinning lines.
Q Which industries can use polymer pleated candle filters?
These filters are widely applicable across multiple industries including petrochemical, metallurgy, textile (polyester melt filtration), electronics, pharmaceuticals, thermal power, nuclear power, food and beverage, automobile manufacturing, and more.
Q How do you clean and maintain industrial pleated candle filter cores?
Cleaning methods depend on the filtration system. Some systems support backwashing with a CIP (Clean-In-Place) design. In most cases, filter cartridges must be removed from their housings, sterilized, and washed manually. After cleaning, they should be thoroughly dried and sealed or vacuum-packed to prevent contamination or wear before reuse.
Q What connector types are compatible with your candle filter elements?
Our candle filter elements support a wide range of connector types including 222, 226, 215, M36, M28, M24, M22, and M20, ensuring compatibility with most standard industrial filtration housings and systems.
