Electrostatic Backpack Trigger Sprayer features a special technology that quickly and efficiently sterilizes offices, restaurants, universities and other public areas. The electrostatic spray-cleaning mechanism electrically charges your chemical solution so the solution quickly bonds to surfaces instead of falling straight to the floor. That means faster sanitizing times. Applying the trigger sprayer with a range up to 15', backpack design, lithium battery source and 16-liter tank, you can cover a large area with minimal hassle. Use both indoors and outdoors. A single charge lasts 2.5 hours for long, continuous work with no pollution, zero emission, no exhaust and low noise. Flow rate ranges from 15 to 50 microns. Trigger sprayer is easy to use with a one-button start and features a military-grade, waterproof, high-speed brushless fan for durability. Recharge quickly - only 90 minutes for a full charge. Use the large-caliber water inlet with any water-soluble chemical.
