“In the 8 years that we have been using these transmitters, we have had clear and clean basin water and never had clogged filters again.
The basin is free of biofilm and the water is always clear and clean. We are extremely satisfied with the performance of the 2 ultrasonic transmitters in our basin. (approx. 2,400m2)”
