Technical characteristics
1.High fineness of filter, stable quality of outlet water
2.Self-detection and response functions are deployed to make automatic backwash to deal with unstable fluctuation of
   water quality without manual operation.
3.Control system with double functions of differential pressure and time presetting can quickly make response and
   precisely operate; backwash differential pressure or time preset value can be flexibly adjusted on the basis of different
   water sources and filtration fineness.
4.Cleaning is efficient and thorough; filter screen can fully restore to the original status, hence it can be permanently used
   without replacement.
5.Operations for producing water will not be interrupted at the time of backwash and will continue, and is stable and
   reliable.
6.Time for backwash is short; water consumption for backwash is only 0.001～0.002% of water quantity produced under
   normal condition, and meanwhile water, electricity and energy will also be saved.
7.Compact and rational design occupies small area and facilitates flexible installation and movement.
8.Equipment has small quantity of wearing parts without consumable materials and is operated and maintained at low
   cost and simple for operation and management.
9.It has found wide applications and is suitable for different quality of water sources and water use.

Technological innovations
1.316L stainless steel sintered filter screen is firstly adopted and features high strength, high fineness and corrosion
   resistance; its highest filter fineness can reach 2 micrometers.
2.atented internal mechanical structure is adopted to achieve high pressure backwash function; external high pressure
   backwash of filter screen combined with internal self-priming can fundamentally remove the impurities in filter screen
   and clean all areas; and no mitigation occurs on flux so as to ensure the filter efficiency and long service life.
3.Differential signal for leaning is transmitted by means of pressure difference transmitter to overcome the shortcoming of
   large inaccuracy of differential pressure switch.
4.Transmission mechanism is made in built-in mode to be isolated from flow components and equipped with disengaging
   protection function to prevent motor or components of filter body from damaging to ensure stable operation.
5. The drain outlet featuring simple and practical style is made with hydraulic seal and requires no electromagnetic valve
    or other vulnerable sealing elements.
6.The flanges in inlet and outlet are designed in flexible structure; screw can be flexibly rotated and adjusted and is easy
   for on-site installation.  
7.Innoxious anti-rot material is adopted inside, which has good performance in weather resisting property, acid and
   alkaline resistance, salt spray resistance and mould proofing.
8.Electrical appliance adopts integrated control mode and exercises remote control.
