“In the 5 years we have been using these transmitters, we have had clear and clean basin water and never had clogged filters.
The pool is free from biofilm and the water is always clear and clean. We are very satisfied with the performance of the ultrasonic transmitters in our basin. (ca. 2,400m2)".
