Single-fluid or hydraulic spray nozzles utilize the kinetic energy imparted to the liquid to break it up into droplets. This most widely used type of spray nozzle is more energy efficient at producing surface area than most other types.
What is a flat fan spray nozzle? Flat Fan spray nozzles produce a fan-shaped pattern, that is mainly produced by two methods; an angled cut or groove, with which the water is hydraulically driven to produce the flat pattern, or via a sloping deflection face with uses the slope to drive the spray pattern.
How does a flat fan nozzle work? The PNR K series flat fan nozzle works by deflecting the liquid off a machined surface that is cut into the side of the nozzle. The nozzles are often referred to as flood jet spray nozzles. This design produces a very wide angle flat fan pattern with medium droplets and medium impact.
What are the different types of spray nozzles? There are 5 basic spray pattern types: flat fan, solid stream, full cone, hollow cone and mist/fog.
Which type of nozzle is used for herbicide spray?
Regular flat-fan nozzles are used for most broadcast spraying of herbicides and for certain insecticides when foliar penetration and coverage are not required. These nozzles produce a flat oval spray pattern with tapered edges (Figure 1).
How do I choose a nozzle? Selecting Your Nozzle Size You’ll want to determine the nozzle flow rate at gallons per minute (gpm). To find that, start with your application rate in gallons per acre (gpa). Next, find an efficient and safe ground speed in miles per hour (mph). Then, determine the spray width per nozzle (W).
How does a spray nozzle work? – Related Questions
How do you pick spray tips?
To Choose The Right Tip For Your Spray Project, Follow These Recommendations: Choose a tip with an orifice size rated for the paint or coating you’ll be spraying. Light coatings such as lacquers, stains, and enamels require a small tip, while heavier coatings such as texture require larger spray tips.
What is a flat spray pattern?
Flat spray nozzles produce small- to medium-sized drops forming a flat or sheet-type spray pattern that’s typically used in manifolds and headers. The flat spray pattern is ideal for cleaning, rinsing, pressure washing, cooling, coating and surface preparation. Nozzle styles include threaded, flanged and quick-connect.
What do the numbers on spray nozzles mean?
Most companies identify their flat-fan nozzles with a four or five digit number (Figure 2). The first numbers are the spray angle and the other numbers signify the discharge rate at rated pressure. For example, an 8005 has an 80 degree spray angle and will apply 0.5 gallons per minute (GPM) at rated pressure of 40 psi.
What are the three types of nozzles?

Where is a fan nozzle used for?
Flat-fan nozzles are widely used for broadcast spraying of herbicides. These nozzles produce a tapered-edge, flat-fan spray pattern (Figure 2A).
What are different types of sprayers?
- Knapsack Sprayer.
- Portable Power Sprayer.
- Knapsack Power Sprayer.
- Mist Dust Sprayer.
- HTP Sprayers.
- Orchard Sprayers.
How do I choose a nozzle size?
The correct nozzle height is measured from the nozzle to the target, which may be the top of the ground, growing canopy, or stubble. Use 110-degree nozzles when booms are less than 30 inches high with 30-inch nozzle spacing; use 80-degree nozzles when the booms are higher.
How do you calculate spray distance from a nozzle?
Multiply your nozzle’s velocity by the time from Step 2. The number you get is the distance the water will spray out of the nozzle. For example, if the nozzle sprays water at 5 meters per second and you’re using 3 seconds as your gauge, 5 x 3 equals a distance of 15 meters.
What is a 311 spray tip used for?
6 inch spray pattern ideal for narrow surfaces such as fences, decks and furniture. The . 011 inch hole size optimal for spraying thinner materials like semi transparent stains, water sealers, stains or polyurethanes.
What is a 511 spray tip used for?
511 – RAC IV Spray Tip RAC 4 SwitchTips are used for both residential and professional coatings, and are available in numerous different tip sizes available. Graco RAC IV also include OneSeal for most common coatings, which help to prevent leaks at the tip guard, and are quick and easy to change.
What is a 211 spray tip used for?
The 211 spray tip is used to work with light lacquers and spray more accurately. For example, to paint beams and window frames. To paint larger surfaces, such as ceilings or tables, it would be more appropriate to use a 411 spray tip with lacquers or paints / interior materials.
What is a fan spray?
Product Overview The Fan Spray is a ground spray element that emits a sheeting fan water effect in an outward arching pattern.
What does spray angle mean?
The spray angle is the opening angle which the nozzle jet of droplets forms at the moment when it leaves the nozzle orifice, and it is one of the fundamental parameters for the choice of a given nozzle.
What is spray pattern?
A spray pattern refers to the shape of a fluid that is released from a pressurized source. Spray patterns determine the degree of evenness with which a protective fluid coating is applied to a surface. A good spray pattern ensures better corrosion prevention.
What’s the difference between a 515 and a 517 spray tip?
For example a 517 tip will spray 10 inches wide, through an orifice size of 17 thousandths of an inch. A 515 tip will spray 10 inches wide, through an orifice size of 15 thousandths of an inch and a 513 tip will spray 10 inches wide, through an orifice size of 13 thousandths of an inch.
What is a 315 spray tip used for?
The 315 tip is ideal for fence picket priming and painting. The 6” fan pattern minimizes overspray when spraying pickets. Worked great even with a 10 year old spray gun!
How does a fine mist sprayer work?
Fine mist sprayers have grooves on the inside of their orifice cups (fancy name for the little piece of plastic through which the liquid sprays). They have one tiny hole for the liquid to spray out of, and the grooves and tiny hole result in a fine mist. Treatment pumps, on the other hand, don’t have this orifice cup.
What is a fan type nozzle?
Fan Nozzles Flat fan spray nozzles feature a fan spray pattern with spray angles between 0°-110°. They produce a uniform distribution of small to medium size droplets. They are used in chemical cleaning, product washing or rinsing, pressure cleaning, coating, etc.
What is a deflector nozzle?
What is pump nozzle?
The pump suction nozzle is the cross-section (circular cross-section) to be defined at the pump casing’s inlet side as a boundary between the suction-side section of the pump system and the pump itself (inlet cross-section).
What is hollow cone nozzle?
A hollow cone nozzle sprays fluids in a ring-like pattern around a given radius. Hollow cone nozzles produce a good interface between air and the surface of the droplets.
