Product Q&A

Q:What are the main applications for this filter?

It is used for golf course and sporting field irrigation, industrial pre-treatment of UF/RO and wastewater recycling, primary filtration for irrigation systems, HVAC cooling tower filtration, metal processing plant water cooling, and mining process water cleaning.

Q:How does the automatic backflushing process work?

When the pressure differential across the filter reaches a preset maximum value, a switch senses this and sends a signal to the controller. The system then initiates backwashing, where pressurized water flows in reverse direction to suspend the filter bed and wash out dirt particles through the back-flush valve.

Q:What are the technical pressure requirements?

The minimum pressure required is 0.15Mpa, and the maximum pressure is 1.0Mpa. The maximum working pressure for the tank is 10 Bar, with a minimum backwash pressure of 2 Bar.

Q:Is customization available for this product?

Yes, we offer full customization including customization from samples, designs, minor customization, and flexible customization. OEM and ODM services are also available.

Q:What is the minimum order quantity?

The Minimum Order Quantity (MOQ) is 1 piece.
