New automatic backflush filter Principle of BOCIN automatic backflush filter
Continuous and versatile operation Self-cleaning process without interruption of the filtration process Backflushing through intrinsic medium Backflushing activated by differential pressure and / or time-interval setting
Durable construction Slot type filter elements with triangular profile for wear-resident operationAdapted for extreme operating conditions Ensuring long service life with minimal maintenance
Flexible design with optimal flow characteristics Adaptability to existing pipeline configurations Minimal pressure loss at the highest possible flow rates
Optimal backflush process Slotted type filter elements and smooth filter surface enable additional jet-effect Optimal backflush process due to time-controlled back flushing and surge cleaning Even the smallest particles with adhesive properties are detached from the filter elements

BOCIN Automatic Back-flushing Filter can remove the solid particles from various water resource and low viscosity liquid (e.g. machining coolant). It makes the fluid meet cleanness requirement and protects downstream key equipments from clogging, abasing and fouling. It increases the key equipment running efficiency and service life. BOCIN Automatic Back-flushing Filter automatically works continuously on-line and reduces the downtime cost, maintenance cost and labor cost. BOCIN Automatic Back-flushing Filter is the advanced solution for the self-cleaning filtration of water and low viscous liquids.
BOC AC-Backw series are kinds of automatic backwashing self-cleaning filter suitable for demanding environments, for different application requirements ,3500micron -50micron filter screens are available.with 8"-36" inlet/outlet diameter. The self-cleaning filtration is started by a differential pressure switch which is monitoring the pressure difference on the filter inlet and outlet. Continuity water supply: very less cleaning water requirement ,just 1% of the out water.the flushing time is2-15 seconds, and the whole system is continuity water supply. High filtration precision: the filtration precision can be up to 20 microns, with a variety of precision filter screens. Large filtration area: the standard effective filtration area is larger 7 to 40 times than the entrance area. Reliable cleaning: there are a variety of control modes, such as manual, pressure difference , time, setting and PLC program logic control . Low-cost and simple installation: various structure forms, suitable for installation various of conditions. Long service life: more than 10 years ; the filter screen is made of stainless steel, and if necessary, the filter screens of different specifications can easily be replaced.
