injector parts

While there are different types of injection systems, this module will focus on one particular water-driven chemical injector, the Dosmatic Advantage A30. This injector is designed to proportionally inject completely dissolved chemicals that are recommended and approved. A great advantage of this injector is that it is water-driven and does not require electricity. Other injectors include pump driven and venturi siphon injector systems (visit the injector gallery).


This particular injector is often used in greenhouse hydroponic systems. A water driven proportional injector receives a fresh water supply from an intake PVC pipe and mixes it with whatever water-soluble fertilizers, acids, wetting agents, chlorine, disinfectants, iodine or antibiotics that might be added to the water in a mixing chamber.
