Advantage

  • Made from premium polypropylene (PP), our knapsack sprayer’s tank and grip are robustly designed and fortified for durability.
  • The shoulder straps, crafted to automotive standards, ensure a secure and comfortable fit without slippage or wear over extended periods.
  • For user comfort, a ventilated massage pad is integrated into the backrest, providing relief and enhancing breathability.
  • A precision-engineered filter is included to prevent clogging, ensuring a smooth and uninterrupted spraying experience.
  • The heat-dissipating base plate is reinforced to efficiently manage thermal loads, contributing to a longer operational life for the motor.
  • The caps are thoughtfully double-layered, providing a convenient storage solution for small items and accessories.
  • Safety is a priority, with waterproof seals safeguarding the switch and charging port against the elements.
  • The battery status is indicated by a color-coded system: a red light signifies low battery, while green indicates a full charge.
  • Equipped with a smart three-stage charging process, our charger employs high-frequency switching technology to optimize battery performance and guard against overcharging.
  • The sprayer’s water pump is distinguished by its high-pressure output and is available in three models to suit various applications: a reflux pump, an intelligent pump with auto shut-off, and an intelligent dual pump system, also featuring auto shut-off. Please note, the dual pump option is available for 18L and 20L models.
