Spray disinfectants or insecticides through stadiums, worksites, and other large outdoor areas—these foggers treat an acre of space in 30 minutes with only one refill. A powerful fan propels mist forward up to 40 ft. or upward up to 25 ft. With a built-in fuel tank, they don’t require an outlet like electric foggers or the effort of hand-pump foggers. Set your preferred spray pattern by adjusting the flow rate and droplet size; spray with greater flow and droplet size for more concentration, or spray with less flow and smaller droplets to cover a broader area. Keep flow and droplet size settings in place with the power lock. The throttle grip is adjustable for comfort. These foggers meet California Air Resources Board (CARB) air pollution standards. Not for use with oil-based liquids and other flammable products.
