Spray Air Technology

The most precise application technology available

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


How the Spray-Air technology works

  • The Air Nozzles, spaced every 10" along the air boom, atomizes the spray droplets using Dial-A-Drop™ technology. This creates the optimum-sized droplets that are not affected by speed and pressure changes, ensuring a uniform application over the entire field.
  • The Air Nozzle 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 Nozzle allows for a very efficient use of water, often in the range of 2 to 5 gallons per acre for herbicides, and generally from 5 to 10 GPA with fungicides.

Droplet Size Management

Follow the ASAE Droplet Classification Standard with Dial-A-Drop™ technology.

Benefits of using Spray-Air technology*

  • Maximize Productivity. The superior plant coverage from the use of the Air Shear Nozzle enables you to use only the minimum amount of herbicide required, and no more.
  • Lowest Water Volumes. Use the lowest possible carrier volumes for herbicide, desiccant, insecticide, and especially fungicide applications. Spray from 2 to 10 gallons per acre.
  • Fungicide Applications That Work. Simply stated, the Spray-Air technology is proven to be the best method to apply fungicides for superior disease control! Benefit from dense canopy penetration and total plant coverage with often only 5 to 10 gallons of water per acre!
  • Application Versatility. Three application methods to choose from
  • Spray-Air Air Nozzle application to maximize coverage and efficiency
  • Conventional flat fan nozzles for higher volume applications over 10 gallons per acre
  • Use conventional nozzles + air blast from the Air Nozzle for classic Air Assist to maximize coverage in higher volume applications
  • Environmental Stewardship. Spray-Air owners practice environmental stewardship by using only as much chemical and water as required, reducing soil and water carryover of crop protection products.
  • Return on Investment. Operator surveys show $6 to $10 per acre in application cost savings
