Safe Chemical Injection For Spas

Mazzei® Venturi Injectors deliver chemicals more safely and with greater precision and reliability than traditional delivery methods. With no moving parts, the Mazzei system is also a safe system because the injected material is not under pressure. If the water flow stops, injection stops instantly. Simple to use and self-priming, Mazzei Injectors are able to run dry with no problems and because they are made with special thermoplastics they last longer. The system uses differential pressure between inlet and outlet ports to create a vacuum, which draws chemicals through the suction port. Internal mixing vanes help ensure even distribution, and most installations do not require a pump or motor.
