What is a Venturi Fertilizer Injectors?
 -- A venturi is a device which creates a vacuum when fluid flows through it. The fluid which creates the vacuum is know as the motive fluid. The motive fluid for irrigation injectors is the irrigation water itself. Vacuum created by the venturi sucks fertilizer or chemical into motive water.

How to work a Venturi?
-- Our Venturi are water driven, ie they are driven by the pressure of the main irrigation pipeline. The energy to run these devices reduces the irrigation water pressure of the water line.

Applications:
--It is important to choose the model size carefully; too large and the unit will not draw the fertilizer at all,too small and you will restrict the flow of the system.
 If in doubt always choose a smaller size, put it on a bypass assembly which allows you to adjust the flow throught the venturi injector and does not restrictthe flow as much.
