air bubble jet

Air Bubble Jets - a proven effective spray tip that has been in use for 16 years in Europe, 11 years in Canada and 6 years in the U.S.A. - over 15 years of worldwide experience on top of the extensive 5 years of development and testing with different crops & chemicals to ensure they did as promised when reaching the marketplace.

Made in England, these sprayer nozzles provide superior coverage, by reducing the number of small (driftable) droplets, and creating air bubbles in larger droplets, ensuring more even dispersion of expensive chemical products.

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.

DiagramThe 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.
