Argon arc welding technic was adopted in each sealing surface, and it was multi-fold structure folding technic that has been taken in the manufacturing process of filtration layers.

A complete filter element has been made up, under the action of enlarging filtration area and the action of evenly distributed apertures.

Because of the corrosion resistance; thermostability; acid and alkali resistance; organic solvents and drugs resistance; this kind of filter elements is able to operate properly at 500 degree centigrade. Thus, the high-pressure backwash folding filter elements could be used to filter high-temperature exhaust gas from boilers and incinerators which results from the glass industry.

The precision could be customized to be 1-200 microns, according to the actual demand of filtration system. And the material would be selected among SUS316L, 304, or Iron chromium aluminum fiber.

What's more, owing to its high porosity, the permeability could be so excellent that the high-pressure backwash folding filter elements are often used to filter a variety of polymer melts in the chemical fiber thin film industry.

Another advantage of high-pressure backwash folding filter element is the outstanding mechanical strength, which make the filter operate under a pressure of 0.1-30MPa.

What makes it easier to process welding is the point mentioned above, too. There is a necessary understanding of the high precision which makes the whole filtration system more suitable for high-viscous liquid filtration.

Through the anti-flushing method, it becomes easier for the filter elements to be cleaned, thus being replaced after a longer time.
