Feili 1.5 Inch PVDF Venturi Injector
This is our 1.5 inch model. Water flow is 4 to 6.5 tons per hour. We use it for food plants, beverage lines, and large fish farms.
No moving parts inside. Water goes through a narrow throat. Speed picks up. Creates a vacuum. That vacuum pulls ozone into the water. Simple.
Made of PVDF. Ozone eats metal. Makes regular plastic brittle. PVDF just keeps going. We have customers running these for 5 to 8 years without changing them.
275mm long. 1.5 inch male threads (DN40) for connections. Suction port is a 12mm barb. Can also take a 1/2 inch male thread adapter. Ozone suction is 7 to 10 cubic meters per hour. Liquid draw is 320 to 680 liters per hour.
Pressure for liquid‑liquid mixing is 0.5 to 1 MPa. For gas‑liquid mixing, 0.3 to 0.6 MPa.
This is one of our better selling Venturi Injectors.
Who Actually Uses This
Food and drink plants. Dairies. Juice bottlers. Breweries. Need sterile water for pipes, tanks, and bottles. Ozonated water works. PVDF handles CIP cleaning. Lasts for years.
Cooling towers. Cooling towers grow bacteria. Legionella. Biofilm. Ozone stops it. No chemical drums to handle. This is a classic Ozone Venturi Mixers application.
City water and wastewater. Small community water plants need lots of disinfection. Chlorine leaves by‑products. Ozone does not. This injector puts ozone into water lines or wastewater pipes. Kills bacteria and viruses. Oxidizes contaminants. It is a key Ozone System Parts component.

FAQ
Q: How long does this last?
A: Install it right. Clean it regularly. 5 to 8 years. Longer than metal or standard plastic. These Venturi Injectors for Ozone are built to last.
Q: Can I run multiple injectors together?
A: Yes. Parallel setup increases total flow. Each injector needs its own check valve. Otherwise they interfere with each other.
Q: How do I clean a clogged injector?
A: Soak in citric acid or vinegar. Dissolves scale. Then rinse with clean water. Do not scrape the throat. That part is precision machined. Scrape it and it is ruined.
Q: What size ozone generator works with this?
A: For regular disinfection, 10 to 20 grams per hour. For advanced oxidation, 20 to 40 grams per hour.
