Venturi Injectors

Venturi Injectors are precision devices that use pressure differential to draw and mix liquids or gases into a water stream — ideal for chemical dosing, fertigation, ozone injection, chlorination, and air induction applications. Compact and efficient, Venturi systems operate without moving parts, relying on fluid velocity to create a vacuum that pulls in the injected substance.

These units are widely used in irrigation systems, water treatment plants, aquaculture, hydroponics, and chlorine or ozone dosing setups. Constructed from high-grade chemical-resistant plastic, PVC, or polypropylene, they ensure durability even in demanding conditions.

This collection includes:
• Venturi Injectors – Sizes from 1/2" to 2", suitable for various flow rates
• Fertiliser & Chemical Injectors – For irrigation and dosing systems
• Ozone & Air Induction Venturis – For oxidation and aeration applications
• Inline Suction Venturis – With built-in threaded or barbed ports
• Accessories & Check Valves – For backflow prevention and setup control
• Brands Available: Mazzei, Cepex, local alternatives

✔ Passive injection – no electricity required
✔ Ideal for fertiliser dosing, ozone mixing, and air entrainment
✔ Easy to install inline on pressure side of pump
✔ Efficient, compact, and corrosion-resistant
