Miller Spray-Air: Less drift, less water, more coverage!

When coverage is critical and you need a deep canopy penetration to kill the target pest, be it weed, disease, or insect, look no further than Miller’s Spray-Air air boom technology.

The unique air nozzle spray system puts instantaneous control of droplet size, spray pattern, and the speed of the air blast spraying into the crop right at your fingertips.

There is no other technology available that will give you coverage as good as this, with the lowest application rates possible.

How Spray-Air technology works

The patented Shear Guard PLUS Air Nozzles, spaced every 10" along the air boom, atomise the spray droplets. This creates the optimum-sized droplets, which are not affected by speed and pressure changes, ensuring a uniform application over the entire field.
The Air Nozzle’s 160+ km/h air blasts the spray droplets deep into the crop canopy, ensuring complete top-to-bottom leaf surface coverage. No other application technology can measure up to the total plant coverage from the Spray-Air nozzle.
Because of the smaller controlled droplets and directed air blast, the Air Nozzles allow for very efficient use of water, often in the range of 18 to 46 L/Ha for herbicides, and generally from 56 to 93 L/Ha with fungicides.

Features

Utilise minimal carrier volumes (20 to 80L/Ha) for herbicides, desiccants, insecticides, and fungicides applications.
Achieve superior plant coverage with the Spray-Air Nozzle, using the minimum chemical necessary.
Spray-AirSpray-Air technology ensures dense canopy penetration and total plant coverage, requiring only 20 to 80 L/Ha.
Choose from three methods: Spray-Air air nozzle for optimal coverage and efficiency; conventional flat fan nozzles for higher volume applications; or combine conventional nozzles with Air Nozzle for classic Air Assist in high-volume applications.
Spray-Air owners practice environmental stewardship by using only as much chemical and water as required, reducing carryover of crop protection products.
Operators save $6 to $10 per acre in application costs by employing the lowest, most efficient methods.

Droplet size is the key to coverage.

Do more, with less.
Applying crop protection products with smaller droplets results in significantly more coverage than large droplets when applying the same carrier volume.

This is why the Spray-Air™ nozzle allows for a reduction in water carrier volumes over conventional flat fan nozzle applications: smaller droplets mean more surface coverage, requiring less water and the lowest rates of active agent possible!

Large coarse droplets (particularly 400 microns and larger) tend to miss the leaves, bounce or runoff, or pool in concentrations.

Only fine & medium droplets provide consistent & uniform surface coverage.
