Built for comfort, built for convenience, built to last—470 Professional Series Backpack Sprayers stand out with a flexible, ergonomic design that makes them ideal for virtually any spraying task, from the largest to the smallest. Heavy-duty, high-performance diaphragm pump accommodates wettable powder, liquid formulations and even undiluted bleach solutions. Superior to metal regarding both break and corrosion resistance, its ultra-violet-light-resistant HDPE tank features an extra-large capacity and a translucent color, allowing you to cover more ground while making it easy to monitor remaining product levels. Viton® seals in key locations ensure superior chemical-resistance for long-lasting, leak-free performance. Adjustable pressure regulator provides four output settings, with the widest possible range, to ensure that users have what they need to get the job done right. A lock-on/lock-off lever located on the commercial-quality valve helps operators minimize the potential for "trigger-finger fatigue." Rugged metal frame delivers rock-solid stability. Deluxe, adjustable padded shoulder straps and waist belt provide the support required for safe and comfortable use. A large-diameter top opening enables easy filling and cleaning, and an extra-large carrying handle with an attached wand retainer allow for convenient transport and neat storage. Several removable nozzle types (including premium TeeJet® nozzles) can be attached to the unbreakable wand so that you can tailor its performance to your chosen task.
