Filtration & Cleaning Process for CAF-700 & CAF-7500 Series Electric Self-Cleaning Screen Filter supplier in Semenyih

Water enters the filter through the "Inlet" (1) and passes through the fine screen (2),
which purifies the flow by separating smaller particles from the water. As more water
flows through, impurities build up on the fine screen. As impurities on the screen
accumulate, a pressure imbalance is built up between the internal section of the fine
screen (2) and its external section.

Cleaning Process
When the difference in pressure (ΔP) reaches the preset value on the differential
pressure indicator, or the duel time between flushing passed, series of events is triggered
while water continues to flow to the system units. The controller transmits a signal for a 10
second flushing cycle. The flushing valve (4) opens, pressure is released from the inner
side of the fine screen (2).
The electric motor (5) simultaneously rotates the brushes (3) around its axis. The brushes
wipe all the dirt and efficiently clean the entire internal screen (3) surface.
At the end of the 10 second cycle the flushing valve (4) closes and the operation of the
electric motor (5) is stopped. The filter is now ready for the next cycle, with clean and
filtered water flowing through the "Outlet" (6).
The 10 second flushing cycle resumes operation whenever the difference in pressure
reaches the preset pressure value set on the differential pressure indicator. If the
pressure difference remains unchanged after one cycle, another cycle will start after a
delay of 10 seconds.
