Automatic backwash filter is a kind of self-cleaning filter that consists of multiple stainless steel filer elements and can continuously perform filtration for 24 hours. It can effectively filter out solid particle contaminants from various water and low-viscosity liquids like rolling emulsions to make the liquid cleanliness meet the system operation and downstream process requirements and protect key downstream equipment. It is widely used in oil & gas, metallurgy, marine filtration systems, water treatment, Pulp & paper and other industries.

Continuous automatic online filtration, no flow interruption when back-flushing, reducing downtime and maintenance cost
Compact design, super high filtration capacity in single filter,remarkably saving the installation space and construction cost
Various filter housing materials and filter element materials available, meeting various filtration requirements of raw water,cooling water, process water and sea water
Multi-candle structure, large filter area, high dirt loading capacity, low surface velocity, low pressure drop, lower back- flushing frequency and less water waste
V-SLOT high performance filter element, V-shape slotted opening, efficient back-flushing performance especially when filtering sticky contaminants
Rigid structure standing high pressure impact, high reliablity with long service life usually over 10 years
lmpulse back-flushing,quick action, high back-flushing intensity, less flushing water purge
Double open ends of filter element allowing water flowing from both sides, no clogging at one blind end of the element, well-distributed filter cake, high flowrate and low pressure drop
D.P. transmitter with local display as the standard configuration, long term steady and reliable, remote monitor support, much better than the common D.P.switch
Reliable automatic control system, friendly Interface and operation, efficiently control the filter running
