Flow Rates, Droplet Sizes and Applications
Liquid flow rate of the Hurricane ES is created by the suction caused by the design of the 3-
nozzles. The Flow rate is regulated by adjusting the metering valve. The liquid flow rate can be
increased by rotating the metering valve knob counterclockwise and decreased by rotating it
clockwise. There are three flow indicator marks on the side of the tank that designate position 1,
position 2 and position 3. Flow rates are shown for these respective positions below. All flow
rate information is based on using water with a temperature of 70 degrees F (21 C). Increasing
the liquid thickness (viscosity) will decrease flow rate and can increase droplet size. This is
because thicker, more viscous liquids are more difficult to atomize. As a rule, thinner liquids
with a lower viscosity atomize easier and flow at higher rates. Refer to the table below for
approximate flow rates and droplet sizes at the various valve settings. Droplet sizes are shown
in microns VMD (Volume-Median Diameter). The VMD is an industry standard and represents
the “middle point” of the spray droplet spectrum of the liquid being applied.
Important: To maximize electrostatic efficiency, only use Water-Base formulations with the
Hurricane ES. Warning: Never use oil-base or flammable formulations with this machine! To
prevent damage to sensitive objects or surfaces like wood finishes, carpeting, upholstery,
etc…do not over apply the formulation being sprayed. If in doubt, always perform a spray test
on a small area to check the effects prior to doing the actual spray treatment.

Insect Control
Depending on the target insect, droplets are generally generated in the 10-30 Micron range so
that even with some evaporation and settling time, the droplets remain in the correct range for
