Ideal for applying degreasers, waterproofing solutions, carpet-care products, disinfectants and 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 and corrosion resistance, the 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, throughout, ensure superior chemical-resistance, and 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 and 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"..
