Product Description

MixRite TF-3 Series Fertilizer Injectors are positive displacement water driven injectors. No electricity needed. There is constant concentration of additive no matter what pressure and flow, the solution is added in proportion to the water flow for accuracy. The TF model has adjustable injection rates. 

TF-3 is a low flow unit used for fertilizers, pesticides and other additives for farming and irrigation. Not intended for strong acids and alkalis or solvents. Flow rates of .088 - 14 GPM.  The TF-3 is identical to the MixRite 571CW & 573CW but with 1” MPT inlet/outlet connections instead of the 3/4" found on the 500 Series models. Plus, the TF-3 flow is slightly higher than the 500 Series models.
