The venturi injectors are an excellent way to inject almost all liquids or gases in the water. These systems are mostly used as a technique to inject air, oxygen or ozone. Many tests have shown a transfer efficiency of over 99% for applications that use ozone. Our injectors are made of PVDF (black Kynar), a high quality plastic that resists ozone oxidation. Works with a minimum pressure of 10 psi and only requires a differential pressure of 16% in order to start the vacuum process. We have made a selection of available models, but you can contact us if you have any special applications. Stainless steel models also available.
