Irrigation system: Why you need a filter?

Do you really need a filter? What is the role of a filter in an irrigation system? What can it bring us?

It is well known that there is at least one filter in every irrigation system, and even many filters in some systems. Many people have asked me, my water quality is clean and free of impurities, so I don’t need to install a filter. On the surface, it is true. But in order for your irrigation system to be used stably for a long time, I want to say, no, you must have it.

In order to ensure the greatest water saving and the best irrigation effect, the water outlets of irrigation emitters and sprinklers we use now are relatively small. Although they have been designed with filtering settings in mind and added, they still cannot avoid blocking after long-term use. Therefore, the filter plays an important role in irrigation system, and it is essential.

How the filter works:

When the filter works, the water to be filtered enters the pipeline through the pressurizing equipment and flows into the filter, and then the particulate impurities in the water are intercepted by the filter screen, while the filtered water flows out from the outlet of the filter.

Here are some filters we often use:
