Battery Knapsack Sprayer for Chemitek Chemical Application

This 12-litre battery-powered knapsack sprayer is designed for professional use with exterior cleaning chemicals, including Chemitek LRA Lichen Removal Agent and other products in the Chemitek range. The backpack design allows operators to move freely around roofs, solar arrays, and façades while maintaining a steady, controlled spray.

The integrated 12 V diaphragm pump delivers consistent pressure and flow, ensuring even chemical coverage without the need for manual pumping.

High-Capacity Tank with Lithium-Ion Power

With a 12 L working capacity and 14 L total tank capacity, this sprayer is built for extended use on site. The 3400 mAh lithium-ion battery powers the pump to deliver a steady output of 0.4–2.2 L/min with a maximum working pressure of 3.8 bar.

This provides the ideal low-pressure application required for lichen, moss, and solar cleaning chemicals.

Telescopic Lance and Comfortable Backpack Design

The sprayer includes a 75–135 cm telescopic lance for extended reach and precise spray control. The 1.7 m reinforced PVC hose provides flexibility during use, while the adjustable shoulder straps and belt distribute weight evenly for comfortable all-day operation.
