DEL UO3 Ozone is considerably more energy efficient than UV ozone generators resulting in low overall power consumption, low heat generation, lower operating costs and less frequent replacement costs. The UO3 is also water back flow resistant, EMI protected and works on 110 or 220 volts (will accept either voltage when plugged in). Attached to the UO3 is a 48 inch 4-Prong Amp cord that plugs into any spa controllers that accepts a 4-Prong Amp type plug.

If you are adding this to a spa that is not ozone ready, you'll also need to buy either an ozone saddle clamp or an ozone inline bypass kit.

For spas that have a small circulation pump installed with 3/4 inch or 1/2 inch tube, you can install an ozone venturi injector.

NOTE: Ozonators are for outdoor use only.
