The self-cleaning filter back-flush filter is automatically removes particulate impurities on the inner surface
of the filter element, in an effective way of mechanical scraping.
The scraper is made of PTFE/ stainless steel, equipped with a
high-precision spring, which can accurately expand and stretch. The
spring is close to the surface of the filter element, and can
efficiently remove impurities.
When the impurities accumulate to a certain extent, the automatic
drain valve opens and the impurities are discharged from the bottom
sewage outlet. The filter is suitable for high impurity content and
continuous uninterrupted production conditions, for it 1) can
realize continuous online filtration and 2) particulate impurities
recovery, 3) generates no filter consumables, and 4) does not need
frequent manual cleaning.
