The SWITCH TANK™ 15 Litre Chemical Sprayer Tank Assembly is an interchangeable tank powered by the M18™ SWITCH TANK™ Powered Base (not included). The 15 Litre Chemical Sprayer Tank Assembly features a dual diaphragm pump for increased durability and maximum pump life, while Viton® seals increase durability against harsh chemicals. The tank also has a wide mouth opening for easy pouring and a strainer that filters out debris from entering the tank. The interchangeable Chemical Sprayer Tank Assembly includes the isolated pump, hose, and wand, with this design allowing users to add on tank assemblies for different spraying applications, eliminating cross-chemical contamination. It also provides users the ability to replace the tank assembly at a lower cost of ownership compared to replacing the entire sprayer unit.
