Venturi Injectors work by forcing water through a conical body which initiates a pressure differential between the inlet and outlet ports. This creates a vacuum inside the injector body, which initiates ozone suction through the suction port. One of its applications is Fertilizer and chemical injection through drip and sprinkler irrigation systems
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 through the venturi injector and does not restrict the flow as much.
Commercial grade one with no moving parts.
It works by suction and will draw liquid fertilizer out of almost any container you provide.
Can be plumbed on a bypass for less restriction (the preferred method), or directly into the main water line.
All sizes have Male Pipe threads on the inlet and outlet, which are easily adapted to hose threads.
