The Dual Auto Kit does exactly what the name says. It connects your Rainbowair Activator 2000 to two vehicle cabins at the same time, cutting your treatment time in half.
Two flanges mount to each vehicle exterior. Two 5-ft hoses run from the Activator 2000. Ozone feeds into both cabins simultaneously from the outside. The generator stays out of the cars. You set the output, set the timer, and one session covers two vehicles at once.
When we brought in a couple of old Hondas with mildew soaked into the plastics and materials from years in unconditioned storage, treating one car at a time would have stretched an already involved process. The Dual Auto Kit is what a production detailing environment calls for. Two vehicles, one session, one setup.
The foam blocks seal each connection point so ozone goes into the cabin instead of escaping around the hose. Run each vehicle no more than two hours per session, then air them out and assess before running any additional time.
