As part of Dosatron’s innovative car wash line, the water-powered Dosatron D14MZ5-D chemical injector has NO tips to worry about, you just set it and forget it, and there is no need for electricity.

With a ratio range of 200:1 to 20:1 and flow range of 0.05 to 14 GPM, the D14MZ5-D is easy to install and maintain. And the adjustable stem allows you to fine-tune your chemical dilution rate on the fly for optimal results.

The D14MZ5-D chemical proportioner’s metal-free piston is corrosion-resistant regardless of high, or low, pH and the mixed chemical discharge is plumbed directly to the arch or foamer. It accurately injects presoaks, detergents, and bug remover.
