Notification on Model Number Adjustment for Certain Product Series

Dear Partners,

Hello everyone!

First of all, we would like to express our sincere gratitude for your long-standing trust, support and goodwill toward ZIGTOO.

As our business continues to grow, the existing model numbering system for certain product series can no longer meet the actual needs of product line expansion. Therefore, we plan to adjust the model numbers of the relevant product series effective July 1, 2026.

It is important to note that this adjustment only involves the naming of product models and will not change the technical parameters, functions, structure, materials, etc. of the products. The original quality assurance and service system will remain unaffected.

For details on the specific product series affected, the crossreference table of old and new model numbers, and the latest product catalogs, please feel free to contact the staff at any ZIGTOO local office. They can also help you check whether the product models you are currently using are within the scope of this adjustment.

We sincerely apologize for any inconvenience this may cause and thank you again for your understanding and cooperation. ZIGTOO will continue to strive to provide better products and services, and we look forward to moving forward together with you.

Thank you!

ZIGTOO Water Industry （Tianjin）CO.,Ltd.
