The Aqueous Product Applicator (APA) device is a multipurpose application system specially designed to deliver a superior misting experience using a battery-operated leaf blower for the air supply and a battery-operated pump backpack to maintain a constant liquid flow. Switch between a precise crack and crevice wand treatment to a broad mist application with ease. Less noise, no gas and oil mixing, less product drift, less carrying weight reduces fatigue, which means safer working conditions. All you need is a leaf blower and a pressurized liquid product tank. You're on the road to a better controlled mist delivery application.
