Built around the immensely popular REC 15 Battery Backpack, the AS 1200 Spray Blower uses air-assisted technology with no need for gas or oil. It's powered by an 18V, quick-change lithium-ion battery, which allows you to spray continuously for extended periods with zero emissions and less noise. Adjustable air speeds and a spray distance up to 42' make this unit ideal for pest/weed control, watering, disinfecting and more.
