Product Q&A

Q:How does the automatic backwashing system work?

The system uses a pressure differential switch to sense dirt buildup. When the preset value is reached, the controller initiates backwashing, where pressurized water flows in reverse to clean the filter bed.

Q:What are the available tank sizes and configurations?

Tank sizes range from 16 to 96 inches. The filter is available in 2 or 3 vessel configurations to accommodate different flow requirements for agricultural and industrial applications.

Q:Can the filter housing material be customized?

Yes, the housing can be customized to Carbon Steel or Stainless Steel based on specific project requirements and environmental conditions.

Q:What is the maximum working pressure for this filter?

The maximum working pressure is 10 Bar, with a minimum backwashing pressure of 2 Bar. The operating pressure range is 0.15Mpa to 1.0Mpa.

Q:What filtration media is used in the filter?

The standard media is Quartz Sand. The filtration process relies on depth filtration through a thick layer of graded particles to remove suspended materials.
