Our SWITCH TANK 15L Concrete Sprayer Tank Assembly is an interchangeable tank powered by the M18 SWITCH TANK Powered Base (not included). The sprayer tank assembly includes the pump, hose, and wand. The design allows you to add on tank assemblies for different spraying applications, eliminating cross-chemical contamination. It also provides you with the ability to replace the tank assembly at a lower cost of ownership compared to replacing an entire sprayer. The 15L Sprayer Tank Assembly features a dual diaphragm pump for longer pump life and Viton seals for increased durability against harsh chemicals. The sprayer tank also has a wide mouth opening for easier pouring and a strainer that filters debris from getting into the tank.
