DESCRIPTION

The ROK 18V Backpack Chemical Pressure Sprayer gives you cordless, hands-free spraying with a 16-litre tank you carry on your back. No extension cords, no dragging a pump unit around — just fill it up, strap it on, and cover the ground.

Two pressure settings (3 Bar and 5 Bar) let you dial in the right output for the job. The lower setting suits fine misting and foliage applications, while 5 Bar gives you more reach and higher-volume coverage at up to 5 metres. Flow rates of 1.25 and 1.45 L/min give you control over how much product you're putting down.

The stainless steel lance and nozzle resist corrosion when handling chemical concentrates — herbicides, fungicides, insecticides, and weed preventers are all suitable. The rubber flexible hose is tough enough for regular use and the tank is designed for easy cleaning between products.

The 18V battery is included in the kit, so you're ready to go straight out of the box.

WHY IT'S PERFECT FOR YOU

If you're regularly spraying herbicides, fungicides, or insecticides across a garden, lawn, or property, carrying a hand pump sprayer gets old fast. The ROK 18V Backpack Sprayer takes the work out of it — 16 litres on your back, battery-powered pressure at the push of a button, and both hands free to aim.

Two pressure settings mean you can run at 3 Bar for finer foliage applications or push up to 5 Bar for longer reach and heavier coverage. The stainless steel lance and nozzle hold up to chemical concentrates without corroding, and the flexible rubber hose makes it easy to work around plants, fences, and tight spots.

The 18V battery and charger are included in the kit — no need to buy separately. Suitable for water, herbicide, fungicide, insecticide, and weed preventer applications.
