Airblast travel speed

Here, in no particular order, are the most common airblast-related questions: What nozzles should I use? How do I adjust my air settings? How much volume should I use? How fast should I drive? The first three questions have long answers that are covered throughout the website and in Airblast101. Travel speed, however, is easy: […]

Validate airblast output – nozzle calibration

The SpotOn SC-4 calibration vessel is much easier, faster and more accurate than the classic pitcher-and-stopwatch approach to timed output tests.

Sprayer math is important. It ensures the operator applies the correct product rate and has enough to complete the job. But, it assumes the airblast sprayer is behaving as expected… and it often doesn’t. After confirming the airblast travel speed, use one of the following methods to assess sprayer output. There are pros and cons […]

Sprayer Math

Stock calculator image.

Sprayer math can be intimidating, but the effort gives solid value. When combined with a calibrated sprayer you reap the following benefits: Estimate how long a job will take. Estimate how much spray mix is required. Estimate how much crop protection product must be ordered for the season. Populate spray records which allow you to […]

How Low Can You Go?

There’s a lot of talk about lowering the boom to reduce drift and make twin fan nozzles more effective. But how low can we actually go with a boom before striping becomes a problem? We’ve done some calculating and have come up with answers. First, a few guidelines. Tapered flat fan nozzles require overlap to […]

Boom Heights at Fan Angles Worksheet

Use this spreadsheet to calculate the minimum boom heights needed for various applications. Some caution: The values are theoretical and assume the fan angles are accurate. Some nozzles don’t produce the advertised fan angle. Enter your actual angle in the spreadsheet The theory assumes that the droplets at the edge of the fan always move […]
