Product Overview
The Dosatron Venturi 3/4" Inline Water Powered Chemical Dosing Injector Kit is a simple, non-electric solution for dosing cleaning chemicals, disinfectants and liquid additives into a water line.
Using the Venturi principle, the injector creates suction as water passes through the unit, drawing chemical concentrate into the water flow without the need for electricity, batteries or a dosing pump motor. It is ideal for washdown, cleaning, sanitising and general chemical dilution applications where a compact inline injector is preferred.
The unit features a polypropylene body, built-in check valve and 12 colour-coded dosing tips for selecting different injection rates. The dosing range is approximately 1:100 to 1:2.3, equal to 1% to 43.6%, depending on the selected tip, pressure, water flow and chemical viscosity.
A simple 3-position handle allows the user to switch between dosing, rinsing and maintenance modes. In dosing mode, water and chemical are mixed together. In rinsing mode, clean water passes through without chemical injection. In maintenance mode, the Venturi can be back flushed to help reduce blockage and simplify cleaning.
The Dosatron Venturi is suitable for applications where constant water pressure and flow are available, and where a cost-effective, low-maintenance chemical dosing solution is required.

Frequently Asked Questions
Does the Dosatron Venturi require electricity?
No. The Dosatron Venturi is water powered and uses the Venturi principle to draw chemical into the water stream.
What is the dosing range of the Dosatron Venturi?
The dilution range is 1:100 to 1:2.3, which is equal to approximately 1% to 43.6% depending on the selected dosing tip and operating conditions.
What pressure range does it operate in?
The dilution range is 1:100 to 1:2.3, which is equal to approximately 1% to 43.6% depending on the selected dosing tip and operating conditions.
What connection size does it use?
The dilution range is 1:100 to 1:2.3, which is equal to approximately 1% to 43.6% depending on the selected dosing tip and operating conditions.
What are the 3 handle positions?
The handle has 3 positions: dosing for water plus additive, rinsing for clean water only, and maintenance for back flushing / self-cleaning.
Does it include dosing tips?
Yes. It includes 12 colour-coded tips that allow different injection rates.
Is the injection rate always exact?
Venturi dosing depends on operating conditions. Product viscosity, pressure and flow can affect the injection rate, so constant pressure and flow are needed for repeatable results.
What is the body material?
The housing is made from polypropylene, which is chemical resistant and recyclable.
