A Venturi Injector can be used with any of our products to help inject ozone or other gases into water. The injector can be paired with any of our generators, but is needed specifically for the SP and Aquatic units. For the use of this venturi, it is recommended to use a 1/2" pvc pipe. This vacuum allows for any additive material to be drawn through the suction port and mix during the application process. This process combines two different substances to create a fluid mix of the two, then releases the combined products through the outlet side. How it Works The vacuum created allows for any additive material to be drawn through the suction port and mix with your water stream. As your infused water exits the venturi, it becomes reconverted into lower pressure energy. This process combines two different substances to create a fluid mix of the two, then releases the combined products through the outlet side. Please note, we do not accept returns on accessories. In Case of Accidental Leakage of Ozone, Keep the Ozone Generator in a Well-Ventilated Area. Ozone Generators Emit Ozone. Do Not Inhale Ozone. Ozone Generators generate high voltage. Our ozone generators are designed and Distributed by A2Z Ozone, Inc. in Louisville, Kentucky USA. EPA Est.: 95432-KY-1 Shipping Policy: All orders and processed and shipped the following business day
