feature of product:

1. Automatic floating ball design, when the card is dirty, it will automatically float, which can prevent the flow from becoming smaller.

2. The open arc-shaped turning cover ensures no water leakage.

3. The circular honeycomb filter material chamber design makes the water flow evenly into the filter material box to ensure the best.

4. The double-layer filter material chamber is highly sealed, and the filter material is replaced without overflowing.

5. Easy and fast installation, easy maintenance and simple operation.

6. Three types of use: pre-filter bucket, small external filter bucket, and series connection as a set of filter systems.

8. When the filter material is blocked, it will automatically open the doffer ball to keep the water flowing, prevent the water quality from being damaged, and prolong the cleaning and replacement time of the filter cotton.

9. Instructions for taking out the cotton ball: When the water pressure increases with the blockage of the filter cotton, the filter cotton will be pushed when the water pressure exceeds the set value, so that the water flow will continue to circulate, ensuring that the flow rate does not decrease.
