How it works

  • Pumps pull product from respective product tanks, blending into a small cone-bottom batch tank (20-60 gal). 
  • You can pump out of batch tanks to fill the drone at any time since the AutoMixer creates a continuous blend.
  • When the batch tank is full, mixer shuts off.
  • The AutoMixer will start back up again as you fill your drone.
