The Ultimate Wash System 1 is a MEDIUM VOLUME wash & rinse system for applying one chemical as foam and rinsing through the same hose. This venturi injection system draws chemical concentrate from any container, mixes it with water, and projects the diluted solution through the 50' discharge hose. The foam wand draws in atmospheric air into the solution to create clinging, wet foam. Remove the foam wand and adjust the ball valves to rinse with clean water using just the garden hose gun. This heavy-duty system is designed to outperform and outlast the competition through superior design and materials.
