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.

The 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.
