The OZ India Ozone Venturi Injector uses the venturi principle to draw ozone gas into pressurised water flow, achieving efficient ozone dissolution without additional pumping energy. Manufactured from SS316L stainless steel for full ozone resistance. The venturi injector is the most economical and reliable method for dissolving ozone into water in STP, ETP, and WTP applications. Available in 0.5 inch to 4 inch bore sizes to match any flow rate from 500 LPH to 2,00,000 LPH.

Frequently Asked Questions
Ozone-compatible materials include PVDF (polyvinylidene fluoride), PTFE, 316L stainless steel, titanium, and silicone. Ozone attacks and degrades: PVC, natural rubber, neoprene, most plastics and elastomers, and copper (at concentrations above 0.3 mg/L). All Ozone India Technology accessories use PVDF or SS316L construction.
A venturi injector creates a low-pressure zone as water flows through the narrowed throat, drawing ozone gas into the water stream by the Venturi effect. The resulting micro-bubbles dissolve at 85–95% efficiency. The water must be at sufficient pressure (1–3 bar) and flow (matched to the injector's rated flow range) for effective ozone transfer.
Yes. All fittings used with PVDF ozone pipe must also be ozone-compatible — PVDF compression fittings or 316L stainless steel fittings are used. Standard PVC fittings must not be used with ozone pipework. All Ozone India Technology PVDF pipe and fittings are pre-certified for ozone compatibility.
Ozone India Technology static mixers are sized to match the ozone generator's sidestream or main water flow and are available for flow ranges from 0.5 m³/hr (50 mm pipe) to 100 m³/hr (200 mm pipe). Static mixers achieve >95% ozone dissolution efficiency when sized correctly for the water flow rate.
