Stainless Steel Pleated Cartridge for for Polymer Melt Filtration

Stainless steel pleated cartridge is made of stainless steel woven mesh or stainless steel sintered felt after pleating and welding. It is generally installed in melt filters to remove impurities from polymer melts in chemical fiber, textile and plastics industries, therefore, it is also known as polymer candle filter or polymer melt candle filter.

According to its filtration layer, it is divided into pleated wire mesh candle filters and pleated sintered fiber candle filters.
The filter area of the pleated cartridge is 5-10 times as large as the traditional cartridge filter, which makes it dirt holding capacity and service life greatly improved.
Filtration efficiency up to 95%
Suitable for melt filter or high pressure, highly corrosive, high viscous or radioactive applications.
Stainless steel construction can be reused after backwashing or ultrasonic cleaning.

Structure

Stainless steel pleated cartridge consists of a position fixing, a pleated layer (protective layer, wire mesh support layer), an inner support tube, an outer protective sleeve and an adapter.

The pleated layer consists of a protective layer, a filtration layer and a support layer. The filtration layer is made of stainless steel woven mesh or stainless steel sintered felt. As the filtration layer has a poor strength, therefore, a protective layer at the top and a support layer at the bottom are provided to protect the filtration layer.
Outer protective sleeve makes the cartridge have a better compressive strength. You may choose to install it or not as your needed.
End caps are available in a variety of types including double opening ends, single opening end, threaded caps, etc.
