Product Q&A

Q:What is the working principle of the filter?

Raw water enters the filter inlet and percolates through a thick layer of graded particles. Suspended materials attach to the media, and clean water exits via the outlet valve.

Q:How does the automatic backwash process work?

When the pressure differential reaches a preset value, a switch signals the controller to start backwashing. Pressurized water flows in reverse to suspend the filter bed and wash out dirt.

Q:What are the available power supply options?

The system supports 220V, 110V, and battery power options to suit different operational environments.

Q:Can the product be customized?

Yes, full customization is available from samples, designs, and flexible customization options.

Q:What is the maximum operating pressure?

The system works between a minimum of 0.15Mpa and a maximum of 1.0Mpa, with a maximum design pressure of 8 bar.
