Ideal for applying degreasers, waterproofing solutions, carpet-care products, disinfectants & more, the 450 Series is engineered with the professional in mind. Rugged, high-efficiency piston-pump requires up to 50% fewer strokes than comparable alternatives to reach maximum pressurization. Superior to metal regarding both break & corrosion resistance, the ultra-violet-light-resistant HDPE tank features an extra-large capacity & a translucent color, allowing you to cover more ground while making it easy to monitor remaining product levels. Viton seals, throughout, ensure superior chemical-resistance, & a pressure-relief valve automatically vents pressure once the maximum compression level is reached to avoid dangerous over-inflation issues. A lock-on / lock-off lever located on the commercial-quality valve helps operators minimize the potential for "trigger-finger fatigue." A large-diameter top opening enables easy filling & cleaning. Webbed nylon carry strap is adjustable to fit nearly anyone. 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. Sprayer / Hose / Nozzle Type: Sprayer; Sprayer / Nozzle Type: 0.4 gpm Brass 80 Flat Fan Nozzle; Adjustable Plastic Nozzle; Hollow Cone Nozzle; Jet Stream Nozzle; Nozzle / Sprayer Settings: On / Off; Hose Length: 48".
