High-throughput security filter

High-throughput security filters are mostly used in water treatment for security filters with large flow rates, cleaning filtration, backwash filtration, condensate filtration, and more. They feature a compact structure, advanced technology, and stable, reliable quality, and are widely applied in multiple fields.

 Dirty water enters from the filter inlet, first passing through the coarse filter screen to remove larger particles, then reaching the fine filter screen. During filtration, the fine filter screen gradually accumulates dirt and impurities from the water, forming a filter impurity layer. Because the impurity layer accumulates on the inside of the fine filter screen, a pressure difference forms on the inside and outside of the fine filter screen. When the pressure difference of the self-cleaning filter reaches the preset value, a switch signal is sent to the control box PLC system to start a cleaning cycle. Cleaning process: The cleaning mechanism of the fully automatic negative pressure suction filter is a stainless steel spiral up-and-down moving suction scanner. It is hollow in structure, with several suction nozzles vertically distributed at certain distances along its axis. The inside of the suction scanner communicates with the 3” drain valve. When the drain valve opens, the pressure difference between the internal water pressure of the filter and the external atmospheric pressure generates strong suction at each suction nozzle. At each suction nozzle, water flows rapidly from outside to inside in reverse, washing impurities attached to the inner wall of the filter screen into the suction nozzle, through the hollow shaft of the suction scanner, then discharged through the drain valve, completing the cleaning process which takes about 30-60 seconds. At this time, the pressure difference returns to normal, the cleaning process ends, and filtration resumes. During cleaning, the system continues to flow.

Performance Features:

High flow security filters are mostly used in water treatment for security filters with large flow, cleaning filtration, backwash filtration, condensate filtration, etc. They have a compact structure, advanced technology, stable and reliable quality, and are widely used in multiple fields.

The equipment uses Parker, 3M, Pall, or domestic high-flow filter elements to achieve a larger effective filtration area, ensuring stable filtration performance in a compact space.

Single filter element flow is larger, with 40" reaching up to 350 gallons per minute (1325 liters per minute). Vertical or horizontal structures can be selected according to space size.

Design Temperature: 5~40℃ (notify if exceeding 80℃)

Sealing Materials: Silicone, Nitrile Rubber, Fluororubber

Connection Types: Threaded, Standard Flange

Recommended Replacement Differential Pressure: 2.0 bar

Maximum Replacement Differential Pressure: 2.4 bar

Surface Treatment: Matte Sandblasting, Polishing

Tank Materials: SS304, SS316L, Carbon Steel Lined with Rubber
