The Super six jet system contains 2 jets X 3 sides = 6 in the basin. The jets are directional and can be aimed to the point of massage. The water flow is injected with air bubble and the volume of bubbles is controlled by a knob on the counter of the basin. The flow of water through the pipes is sanitized by an ozone module. Ozone is also injected into the water stream. Ozone sanitation kills 99.9% of germs and viruses in 20 to 30 minutes during jet use and is safer than chlorine. Most pedicures available have 2 or 4 jets, this system has 6 set in a surround true hydrotherapy configuration. Design X six seat pedicure units only.
