Polyethersulfone foldable filter cartridge is made of asymmetric and high precision PES material. Its asymmetrical loose-compression-loose three-layer structure can effectively reduce the piezoresistance and increase the volume of dirt. It has a characteristic of large filtration area, low differential pressure and high filtration flow.

Because of the chemical resistance and hydrophilicity of the PES material, the polyethersulfone foldable filter cartridge can be widely used for precision filtration in the electronic, pharmaceutical, and food and beverage industries.

1、Polyethersulfone has an excellent hydrophilicity.

2、Large filtration area, low differential pressure, and high flow. 

3、Three-layer structure of filter section (loose-compression- loose). 

4、There is no surfactant in filter. It can reduce the cleaning time.

5、Manufactured in a dust-free environment, and filter cartridge is of high-level cleanliness.

6、End cap and joints are sealed by hot melt and no adhesive.
