Efficient working practices and high performance are called for in enclosed spaces such as conservatories and greenhouses. For such applications, the battery-operated backpack sprayer Solo 417 is the perfect plant protection appliance. Free of emissions and whisper-quiet, the Solo 417 meters out its spray medium from a 18 litre transparent tank made from highly resilient UV-resistant plastic. A powerful 12 volt pump, switchable to two stages with up to 4.3 bar pressure deliver both the pressure and throughput you need. Once the battery has run out, the charger supplied takes just a few hours to recharge the unit. In addition, the Solo 417 is equipped with a comfortable padded backpack support frame with wide shoulder straps that are also padded. The low dry weight of the Solo 417 guarantees tireless working, ideal for spraying pesticides, herbicides, and for general spraying.
