The Multi-Pet Washing System is a combination system for diluting and projecting up to 4 chemicals as airless foam or spray and then rinsing. This system is ideal for bathing pets in professional grooming shops, but has countless potential applications. This venturi injection system uses standard city water pressure (35 - 125 PSI) to draw and blend chemical concentrate into the water stream to create an accurately diluted solution. Project wet, clinging foam using the airless foam wands or use the fan nozzles to project a chemical spray with just the right amount of pressure. Select low or high flow settings for small or large jobs.
