The Clearwater 24hr Ozonator, has a diaprahm air pump which pumps air into the U.V. light chamber and then into your spa and comes out in small bubbles through the diffuser stone which is mounted in the footwell of your spa on the wall by drilling a 27mm hole in the spa and siliconing in.

Because this ozone has its own air pump there is no need for an injection system into the water via a mazzi injector.
