Product Description

Pleated metal mesh filter is made of pleated metal wire mesh material. Choose a combination of three to four layers of metal wire cloth pleated, The inner and outer coarse mesh is usually used as a reinforcement layer or support layer, the micron rating depends on the core filter layer. Pleated metal mesh filters allow for larger filtration areas and high fouling control capabilities, and can also fit into smaller housings, which allow for fine filtration without applying significant pressure.

Product 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.
