Description
Spray Nozzle Characteristics
Spray nozzles are precision components designed to yield very specific performance under specific conditions. To help you determine the best nozzle type for your application, the following chart summarizes the performance that each nozzle type is designed to deliver. Visit youtube.com/sprayingsystems for video demonstrations of spray patterns.

The spray pattern images on the right were acquired in our spray laboratories using Laser Sheet Imaging (LSI). LSI images are collected by passing a laser sheet through a cross-section of the spray plume and imaging with a light-filtered camera. The distributions are directly proportional to the surface area distribution of the sprayed material (red: high; blue: low; black: zero). Volume distributions typically are similar to surface area distributions for these nozzles, depending on the local drop size distributions.
FULL CONE NOZZLES
- Uses a unique internal vane design to produce a solid cone-shaped spray pattern
- Spray pattern consists of medium- to large-sized drops
Typical applications:
- Chemical injection
- Dust suppression
- Fire protection
- Metal cooling
- Washing/rinsing
FULL CONE (SPIRAL-TYPE) NOZZLES
- Produces a solid cone-shaped spray pattern when the fluid exits the voids in the spiral
- Spray pattern is not as uniform as full cone nozzles with an internal vane
- Spray pattern consists of relatively coarse drops
Typical applications:
- Dust suppression
- Fire protection
- Flue gas desulfurization (FGD)
- Quenching
FULL CONE (OVAL SPRAY) NOZZLES
- Uses a unique internal vane to produce a solid cone-shaped spray pattern with oval impact area with a width approximately one-half its length
- Spray pattern consists of medium- to large-sized drops
Typical applications:
- Air/gas washing
- Cooling and quenching
- Dust control
- Fire suppression
FULL CONE (SQUARE SPRAY) NOZZLES
- Uses a unique internal vane to produce a solid cone-shaped spray with square impact area
- Spray pattern is uniform across entire spray area
- Spray pattern consists of medium- to large-sized drops
Typical applications:
- Air/gas washing
- Cooling and quenching
- Dust control
- Fire suppression
FLAT (EVEN) NOZZLES
- Provides even distribution of medium-sized drops throughout the thin, rectangular spray pattern
- When used on a header, nozzles are positioned for edge-to-edge pattern contact
Typical applications:
- Coating
- Cooling
- Moisturizing
- Washing
FLAT SPRAY (TAPERED) NOZZLES
- Produces a tapered-edge flat spray pattern
- Used on spray headers to provide uniform coverage as a result of overlapping distributions
Typical applications:
- Descaling
- High-pressure cleaning
- Label removal
FLAT SPRAY (DEFLECTED-TYPE) NOZZLES
- Uses a deflector surface to form an even flat spray pattern consisting of medium-sized drops
- Large free passage design reduces clogging through the round orifice
Typical applications:
- Showers in papermaking
- Washing
HOLLOW CONE (WHIRLCHAMBER-TYPE) NOZZLES
- Uses a whirlchamber to rotate the fluid and produce a circular spray pattern
- Ideal for use when a combination of small drop size and higher capacity is needed
Typical applications:
- Air, gas and water cooling
- Cooling products on conveyors
- Dust control
- Flue gas desulfurization (FGD)
- Water aeration
HOLLOW CONE (DEFLECTED-TYPE) NOZZLES
- Uses a deflector cap to form an umbrella-shaped hollow cone pattern
Typical applications:
- Decorative spray
- Dust suppression
- Fire protection
- Flush cleaning of tube/pipe interiors
- Water curtain
HOLLOW CONE (SPIRAL-TYPE) NOZZLES
- Produces a circular spray pattern when the fluid exits the voids in the spiral
- Drops are slightly coarser than those in other hollow cone sprays
- Provides a high flow rate in a compact nozzle size
- One-piece design produces maximum throughput for a given pipe size
Typical applications:
- Dust suppression
- Fire protection
- Flue gas desulfurization (FGD)
SOLID STREAM NOZZLES
- Produces a solid stream spray with the highest impact per unit area
Typical applications:
- Cleaning products when complete removal of dirt and debris is required
- Decorative spray ponds
- Laminar flow operations
ATOMIZING (HYDRAULIC, FINE MIST) NOZZLES
- Produces a finely atomized, low capacity spray in a hollow cone pattern without use of compressed air
Typical applications:
- Dust suppression
- Evaporative cooling
- Moisturizing
- Spray drying
AIR ATOMIZING AND AIR ASSISTED NOZZLES
- Produces a variety of cone and flat spray patterns through atomization of liquid by compressed air
- Internal mix impingement atomization forms very fine drops
Typical applications:
- Coating
- Evaporative cooling
- Humidification
- Moisturizing
