The Dramm BP-4 Back Pack Sprayer is a rechargeable, battery-powered sprayer that fits comfortably on your back. Operating at a maximum pressure of 150 psi, the BP-4 offers an adjustable pressure knob for flexibility in spraying. Using the high-pressure setting, the BP-4 atomizes spray solutions better than other backpack sprayers, ensuring excellent coverage. The battery-operated pump ensures even flow rates, perfect for even application of plant growth regulators, insecticides, fungicides, herbicides and other greenhouse chemicals. The BP-4 can run for up to 1 hour on a full charge and recharges in 4 hours. The 4 gallon tank capacity is just the right size. Perfect for spot treatments or concentrated applications, but small enough to still be comfortable to wear. The BP-4Li offers completely variable pressure from 10-150 psi and a swappable Makita 3 Ah Lithium Ion battery. Like its predecessor, the BP-4Li provides a powerful spray with fine droplets. The unit comes with a twin fan nozzle and a conical bullet nozzle. Other nozzle options are available. Additional batteries are available for purchase. Operating time on one battery is 45 minutes.Key Features & Specifications 4 gallon (3.95 gal / 15 L) chemical tank capacity Removable 6V 3.0 Ah lithium ion battery (Makita-compatible swappable) Variable pressure: 30-150 psi Pump suction rate: 0.39 gal/min (1.5 L/min) Continuous spray time: 1 hour on full charge Recharge time: 4 hours Weight 11 lbs empty Includes dual fan nozzle and adjustable cone nozzle Battery indicator shows remaining spray time Priming bubble, tank drain Padded backing and adjustable straps Optional L-5E Lance, Twin Nozzle, Single Fan Nozzle
