Product Q&A

Q:What is the working principle of the filter?

Raw water passes through a thick layer of graded particles like sand or gravel. Suspended materials attach to the media, and clean water exits through nozzles.

Q:How does the automatic backwash process work?

When pressure differential reaches a preset value, the system sends a signal to the controller to reverse water flow, suspending the filter bed and washing out dirt.

Q:What materials are used for the tank housing?

The housing is available in Carbon Steel or Stainless Steel options.

Q:What are the maximum and minimum working pressures?

The minimum pressure is 0.2 Mpa and the maximum pressure is 1.0 Mpa.

Q:Can the filter be customized?

Yes, full customization is available from samples, designs, minor customization, or flexible customization.
