I have started purchasing parts to build my own high pressure fog system to replace the Aquafog fan.
Aeromist has the best prices that I have found for complete systems. I decided to build my own using a variable speed electric drive so that I will have a wider range of output available to me. I purchased a pump head from Aeromist; a CAT brand pump rated at 0.5 gpm when driven at 1725 rpm.

I purchased an "inverter duty" 3-phase electric motor and driver from another company that I will couple to the CAT pump head. This electric motor can be driven as slow as 2 rpm at full torque so I will be able to vary the output of the pump from as little as a few milliliters per minute at 2 rpm up to the full 0.5 gpm (2,000 milliliters per minute) at 1725 rpm. I expect that I will initially run the system at about 400 ml per minute.
