Spiral Nozzle

The spiral nozzle's unique spiral structure allows liquid to rapidly rotate under high pressure, creating a uniform and fine spray. It is ideal for applications requiring efficient coverage and atomization, such as scrubbers, cooling, dust suppression, spray cleaning, humidification, and chemical processes.

Spiral Nozzle Spray Patterns

Single-piece spiral structured nozzles, sometimes referred to as pigtail or mosquito coil nozzles, disperse in a solid cone shape with multiple concentric circles.

Spiral Nozzle Flow Distribution

Spiral nozzles feature a multi-valley flow distribution, with peaks decreasing from the center outwards and a tapering flow at the sides.

Material Options

UPVC (for temperature up to 60°C)
PEEK (for temperature up to 260°C/482°F and highly corrosive chemicals)
PTFE

120° ~ 170° spray angle

The spray angle is from 120° to 170°. This large spray angle design provides larger coverage than general fan and full cone nozzles.
