The Model 484A Venturi Injector is a high-performance tool designed for efficiently dissolving ozone gas into water, making it a key component in many ozone water treatment systems. Using ¾” Male NPT connections for both inlet and outlet, this venturi injector is made from Black Kynar (Polyvinylidene Fluoride), offering maximum ozone resistance for long-term durability. This makes it an ideal choice for ozone systems that demand reliability in even the most challenging environments.

Why the Mazzei Venturi Injector is Widely Used
The Mazzei venturi injector is the go-to choice for ozone injection systems, and for good reason. Its design ensures both simplicity and efficiency in dissolving ozone into water. The process utilizes a pressure differential within the venturi to pull ozone gas into the water stream, making it highly effective at mixing the gas and water. The internal mixing vanes further enhance this process, ensuring that the ozone is thoroughly dissolved.
If you are replacing an existing venturi injector, check the part number located at the center bottom of the venturi (beneath the suction port). It will be a 3-4 digit number. If you’re building your own system or need help sizing a venturi, our team is always available to assist.
How the Venturi Injector Works
A venturi injector works by creating a vacuum that pulls ozone/oxygen gas into the water stream. Here’s a simplified breakdown of the process:
- Water flows through the venturi at high velocity, creating a pressure differential.
- The pressure drop results in a vacuum at the suction port (third leg of the venturi).
- This vacuum pulls in ozone gas, which is quickly dissolved into the water.
- The internal vanes ensure efficient mixing, resulting in high levels of dissolved ozone in the water.
This process makes the venturi injector one of the most efficient methods for infusing ozone into water.
Performance and Application Considerations
The Model 484A Venturi Injector can operate under a wide range of pressures and water flow rates. However, each ozone injection system is unique, and selecting the correct venturi injector for your specific application is crucial. For a more detailed performance evaluation, you can refer to the Mazzei Venturi Injector Performance Tables or contact us directly for personalized assistance.
Venturi Injector Components and Design
The Model 484A Venturi Injector comes with an integrated check valve assembly, which is made from ozone-resistant materials, ensuring durability when exposed to ozone and hydrogen peroxide. The check valve also includes a barbed connection that can be easily modified for threaded connections, providing flexibility in installation.
However, based on our extensive experience in ozone system installations, we recommend removing the stock check valve assembly and replacing it with a stainless steel check valve for enhanced reliability. The standard plastic check valve can sometimes develop leaks or degrade over time, while a stainless steel option provides a more secure, leak-proof connection. This upgrade ensures both greater ozone containment and prevents any potential backflow to your ozone generator.
Optional By-Pass Assembly
In some cases, it’s advisable to install the venturi injector as part of a by-pass assembly. This is especially useful when dealing with higher water flow rates than the venturi can handle or when there’s uncertainty regarding specific suction and water flow requirements. A by-pass provides flexibility in operation and ensures optimal performance of the venturi injector.
We can also provide a by-pass assembly with your venturi purchase if required.
Key Specifications of the Model 484A Venturi Injector:
- Connection Size: ¾” Male NPT
- Material: Black Kynar (Polyvinylidene Fluoride) for maximum ozone resistance
- Application: Designed for use in ozone water treatment systems
- Performance: Operates efficiently over a wide range of pressures and water flows
Tech Tip for Ozone System Installations
For those looking to maximize the longevity and performance of their ozone systems, we strongly recommend replacing the standard Mazzei check valve with a stainless steel version. This small upgrade can significantly improve the reliability of your system, reducing the risk of leaks and ensuring that ozone gas is properly contained.
