The Blue Mule Ultimate Wash System 4 is a wash & rinse system for diluting and applying up to 4 chemicals as foam or spray and then providing a clean water rinse through the same 50’ hose. This venturi injection system draws chemical concentrates from any sized containers, mixes them with water and projects the accurately diluted solutions as a fan pattern spray or rich, wet foam (depending on the chemical and nozzle used). Select high or low flow settings for chemical application and simply turn off the chemical ball valves and open the rinse valve to provide a full force rinse with clean water. This system is ideal for bathing pets in professional grooming shops, but has countless potential applications. This heavy-duty system is designed to outperform and outlast the competition through superior design and materials.
