The 12-volt motor is incredibly dependable and designed for long-life use on your transport tank in any kind of weather. This motor is built exclusively for Fresh-Flo. Used by many tank designers and manufacturers, the aerator comes with a 24” power cord to operate from the truck’s electrical system.
