How Air Bubble Jets Work
The Air Bubble Jet consistently produces
droplets that are 200 - 550 microns in size. Too
big to drift - too small to run off.
Drift occurs when droplets are smaller than
200 microns. Standard sprayer nozzles drift
because they produce droplets that are 50 - 300
microns in size. With a droplet range of 200 -
550 microns the Air Bubble Jet has 90% less
drift than standard nozzles. Run off occurs with
big droplets - 600 microns and over.
Depending on the manufacturer, other low
drift nozzles produce droplets that range in
size from 250 to 1000 microns - that is why run
off can be a problem. With a droplet size of 200
- 550 microns your chemical stays on the plant
when applied with the Air Bubble Jet.
With the twin cap you can use 2 - 5 gal.
nozzles rather than 1 - 10 gal. nozzle. The
advantage is you get over twice as many droplets
per sq. inch for superior coverage. Air Bubble
jet nozzles operate at 30 - 45 psi and have an
overall range of 20 - 90 psi. They can be used
to apply fungicides, insecticides and herbicides
to any crop including potatoes and pulse crops.
liquid being sprayed passes through a removable
tapered nozzle A which accelerates the
liquid and projects the flow into the tapered
mouth of the venturi B.
This creates a
vacuum which causes air to be sucked in through
the two slots marked C.
The mixture of
air and liquid is compressed as it passes
through the mixing chamber D and is then
sprayed through a fan nozzle E.
