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 candle filter element is placed inside the filter housing (housing). It is a compact device that can typically hold 1–20 candles, depending on the size of the filter. The filter element is arranged vertically in the pressure vessel to filter liquids with low solid content. The candle filter allows high productivity, easy bottom sediment discharge.

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.

Frequently Asked Questions (FAQ)

QWhat is a candle filter element and how does it work?

A candle filter element is a tubular filtration component placed inside a filter housing. Polymer melt or liquid is forced through the filter media under pressure, trapping impurities and particulates while allowing the clean fluid to pass through. The elements are arranged vertically inside a pressure vessel, making them suitable for liquids with low solid content.

QWhat filter media materials are available for polymer candle filter elements?

The main filter media options are stainless steel wire mesh and stainless steel sintered fiber. Wire mesh offers smooth pores, easy cleaning, and high temperature resistance. Sintered fiber provides high porosity, excellent air permeability, strong dirt-holding capacity, and superior regeneration ability.

QWhat is the filtration rating range for these candle filter elements?

Our candle filter elements cover a filtration rating range of 1 to 200 microns, allowing them to handle a wide variety of polymer melt filtration applications across different industries.

QWhat is the maximum working temperature and pressure these filters can handle?

The candle filter elements are rated for working temperatures up to 350°C and can withstand an allowed pressure difference of up to 10 bar (14 psi), making them suitable for demanding high-temperature polymer processing environments.

QCan the candle filter elements be cleaned and reused?

Yes. Candle elements made from 304L or 316L stainless steel are designed for repeated cleaning and long-term use. They are highly resistant to high temperatures and corrosive environments, ensuring a long service life and cost-effective operation.

QHow is quality assured before the filter elements are shipped?

Every polymer filter element undergoes bubble-point and air flow testing before shipment to verify product integrity and performance. A test certificate is provided with each lot. Additionally, all elements are laser marked at the bottom of the end fittings for easy identification and traceability.
