3/4 inch PVDF Venturi Injector – Ozone Disinfection Injector

The 3/4 inch PVDF Venturi Injector is built specifically for injecting ozone into flowing water streams for disinfection and purification. It uses the Venturi effect, where water passing through a constricted section creates suction that draws ozone gas into the flow. Made of high‑grade PVDF (polyvinylidene fluoride), this injector withstands continuous ozone exposure and resists corrosion.

Features & Specifications

  • Size / Connection: 3/4″ inlet/outlet compatibility, suitable for standard, larger pipe networks.
  • Material: PVDF construction ensures high chemical resistance and durability in ozone systems.
  • Operating Principle: Venturi effect design allows the injector to draw ozone effectively without additional moving parts.
  • Application: Designed exclusively for ozone injection in water treatment, pools, aquaculture, and industrial sanitation systems.
  • Corrosion & UV Resistance: Suitable for aggressive environments involving oxidising gases and high‑performance water treatment.

Benefits of a PVDF Venturi Injector for Ozone

  • Efficient ozone mixing: Because the injector uses water flow to draw ozone, you save on external pumps and simplify system design.
  • Long service life & minimal maintenance: PVDF is highly resistant, so the unit keeps working under tough conditions.
  • Better water hygiene: With reliable ozone injection, you get strong disinfection and fewer chemical residues.
  • Versatile sizing: A 3/4″ diameter makes the unit suitable for mid‑size commercial or high‑demand systems.

Installation & Usage Tips

  1. Ensure correct flow direction—water enters the main port, ozone is introduced via the side suction port.
  2. Flush the injector before first use to remove any manufacturing residues.
  3. Secure ozone supply tubing to the side port and confirm tight connections—any leak reduces performance.
  4. Use only ozone‑rated tubing and ensure all system components downstream are ozone compatible.
  5. Periodically inspect the suction path, joints, and check for wear or deposits that might restrict flow.
  6. For optimum results, match flow speed and injector sizing according to supplier tables for your ozone generator and pipe size.
