  • Disinfectants


The D14MZ2 is the upgraded replacement for the 11 GPM model, allowing flow rates up to 14 GPM. It offers enhanced UV resistance and is perfect for one-hose operations or for use with our 15-gallon DosaCart or 5-gallon Li'l Bud-D portable fertilizing system.

  • increased water flow
  • Fewer parts
  • Increased chemical resistance
  • A flow range from 0.05 GPM to 14 GPM
  • Injection ratios of 1:500 - 1:50
  • Connections ¾ "NPT upstream and downstream

Model: D14MZ2VFII


Ideal for Garden Centers

The D45RE15 is for growers needing higher flow up to 20 GPM. It has a built-in bypass (on/off switch) and can handle up to two garden hoses on a single injector.

  •      Flow rates from 0.4 GPM to 20 GPM
  •      Connections 1 "NPT upstream and downstream
  •      7-70 psi
  •      Mixing ratios of 1:66 to 1:500
  •      Connections 1 ½" NPT upstream and downstream


The D40MZ2VFII allows flow rates up to 40 GPM and can be installed in parallel for increased flow.
