Nozzle User Guide
This guide was developed to help you:
- Learn more about the technical aspects of spray nozzles.
- Select the spray nozzles best suited to your specific application requirements.
- Maintain your spray nozzles for optimal performance.
The nozzle users guide has the following sections:
- Nozzle Fundamentals
  The Nozzle Fundamentals Guide covers the following:
  - Section 1.1: Nozzle Spray Patterns
    There are many types of nozzles and spray patterns available and your choice will be dependent on your particular operation.
  - Section 1.2: Spray Pattern Geometry
    Spray coverage will vary based on operating pressure, spray height and nozzle spacing. Follow the manufacturer's recommendations to achieve uniform coverage.
  - Section 1.3: Spray Pressure
    Nozzle flow rate varies with spraying pressure.
  - Section 1.4: Droplet Size Basics
    A nozzle's spray pattern is made up of many droplets of varying sizes. Droplet size is the diameter of an individual spray droplet. Droplet sizes are measured in microns (micrometers). One micron equals 0.001 mm (.0000394"). For example, the diameter of a human hair is about 100 microns.
  - Section 1.5: Spray Drift
    Spray drift is an industry-wide term used to describe the physical movement of pesticide droplets or particles through the air outside of the intended target area. Droplets most prone to drift are those less than 150 microns in diameter.
- Nozzle Types
  The Nozzle Type information page covers the following nozzle types:
  - Section 2.1 - Venturi Air Induction Nozzles
    Air induction (AI) nozzles feature two orifices. The first orifice, known as the pre-orifice, meters the liquid flow. The second orifice, known as the exit orifice, is larger than the pre-orifice and forms the spray pattern.
  - Section 2.2 - Extended Range Flat Fan Nozzles
    Extended range flat fan nozzles are widely used because they provide excellent spray distribution over a wide range of pressures. When operated at lower pressures, drift is reduced. Better coverage is achieved at higher operating pressures.
  - Section 2.3 - Pre-Orifice Flat Fan Nozzles
    Pre-orifice flat fan nozzles reduce the operating pressure internally and produce a larger droplet than conventional flat fan nozzles.
  - Section 2.4 - Flooding Type Nozzles
    Flooding type nozzles produce a wide angle flat fan pattern. Pressure changes affect the width of the spray pattern more than with extended range flat fan nozzles.
  - Section 2.5 - Specialty Nozzles
    There are many variations on the basic nozzle types and many other specialty nozzles available as well. Your choice will, of course, depend on your application requirements.
- Selecting The Right Nozzle
  There is a reason why there are dozens of different nozzle types available in hundreds of different sizes, capacities and materials. Each nozzle is designed to yield very specific performance based on what you're spraying, when you're spraying and how you're spraying.
  - Section 3.1 - What Are You Spraying?
    Herbicides, fungicides or insecticides?
  - Section 3.2 - How Are You Spraying?
    Broadacre, Banded, Directed or Mechanical Air Assisted? The answers to these basic questions will get you started.
  - Section 3.3 - What is your tolerance to drift?
    If you answer yes to any of the questions in this section, you may want to consider low drift nozzle
  - Section 3.4 - What is the weight of the spray solution?
    Tabulations in spray nozzle catalogs are based on spraying water that weighs 8.34 pounds per U.S. gallon or 1 kg per liter.
  - Section 3.5 - What is the pressure range of the sprayer?
    Always operate any nozzle in the middle of its recommended operating range for best performance.
  - Section 3.6 - What is the nozzle spacing on the boom?
    The nozzle size you need depends on many factors including the desired application rate, ground speed and nozzle spacing.
  - Section 3.7 - What is the boom height?
    Lower boom heights are usually better as long as proper overlap of spray nozzles is achieved. In general, nozzles with 110° fan angles can be used at lower boom heights than 80° fan angles.
  - Section 3.8 - Which nozzle material is best?
    To determine the best material for your application, you need to know what chemicals you will be spraying and what you perceive to be an acceptable wear life (spray hours) for your nozzles.
  - Section 3.9 - Who is the nozzle manufacturer and why does it matter?
    Once again, because spray nozzles are so small, it may be easy to think of them as simple components. However, spray nozzles are highly engineered, precision components and consideration should be given to the manufacturer and the manufacturer's capabilities. Here's a list of credentials to look for.
