TransJector Plus

Model # 910785

The TransJector Plus is an "adjustable flow" chemical injector for feeding spray bars and arches with chemical solution at up to 9.6 GPM @ 40 PSI. This venturi injection unit uses city water pressure (40 - 125 PSI) to draw and blend chemical concentrate into the water stream and creates a wide range of dilution ratios. Both the water and chemical flow can be adjusted "on-the-fly" via needle valves. This versatile unit can be used for both new installations and to retrofit existing spray bars.
