Description
The M18™ SWITCH TANK™ 15 Litre Backpack Chemical Sprayer with Powered Base delivers ultimate pressure control, with no manual pumping and an interchangeable tank design. Designed to meet the needs of contractors and landscape maintenance professionals, the battery powered backpack sprayer provides instant, constant, and adjustable pressure up to 75 PSI, with a 7.3 m vertical spray distance. The flow rate dial allows users to adjust flow through 5 modes from 0.38 – 2.27 L/min, providing the capability to complete a wide range of applications. Paired with an M18™ REDLITHIUM™ 5.0Ah Battery (sold separately), the Sprayer can discharge 40 tanks of spraying per charge (on Mode 3). The 15 Litre Chemical Sprayer Tank Assembly features a dual diaphragm pump for long pump life and Viton® seals for durability against harsh chemicals. The Sprayer Tank has an optimised design with improved weight distribution, a wide mouth opening for easy pouring, measuring cup, and a strainer that filters debris from getting into the tank. The Backpack Powered Base includes padded straps, lumbar support, and a hip belt, providing comfort during extended spraying applications. The 15 Litre Chemical Sprayer is made up of two components, the M18™ SWITCH TANK™ Powered Base and the 15 Litre Chemical Sprayer Tank Assembly (also available separately as 491619PS). The Powered Base includes the motor, battery compartment, and REDLINK™ electronics, while the interchangeable Tank Assembly includes the pump, hose, and wand. This isolated pump, hose, and wand design allows users to add on tank assemblies for different spraying applications, eliminating cross chemical contamination. The Powered Base is also compatible with the 15 Litre Water Supply Tank Assembly (491619WS).
