No Drip Atomizing Spray Nozzles

All stainless steel construction for durability and corrosion resistance!

nodrip main_new

EXAIR’s no drip atomizing spray nozzles work in the same way our standard atomizing nozzles do, but have the added benefit of positively stopping liquid flow when compressed air is shut off. All models use stainless steel construction for durability and corrosion resistance.


Applications

  • Washing
  • Rinsing
  • Coating
  • Cooling
  • Quenching
  • Wetting (moistening)
  • Humidification
  • Dust Control

Advantages

  • No post spray drip
  • Fully adjustable
  • Easily used with an EFC
  • Maximises liquid dispersion
  • Minimises liquid consumption
  • All stainless steel construction
  • Compact
  • Versatile
  • Interchangeable liquid and air caps
  • Minimises air consumption
  • Fine atomization

EXAIR's no drip atomizing nozzles are available in 3 basic families:
 

Internal Mix:

Internal mix nozzles mix the liquid and water inside the air cap and produce the finest atomization. Internal mix nozzles can be used on liquids with a viscosity up to 300 cp. Both air and liquid sides are pressure fed. No Drip Internal Mix Atomizing Nozzles are for pressure fed applications not requiring independent air and liquid control. Read More >>

 

External Mix:

External mix nozzles have the highest flow rates and allow the air and liquid flows to be adjusted independently. These nozzles are best where precise liquid flow is needed. External mix nozzles can be used on liquids with a viscosity above 300 cp. Both air and liquid sides are pressure fed. No Drip External Mix Atomizing Nozzles are for pressure fed applications with independent air and liquid control.  Read More >>

 

Siphon Fed:

Siphon fed nozzles require no liquid pressure and can be used with gravity fed liquids or lift liquids from a siphon height as much as 36 inches (91cm). Siphon fed nozzles can be used on liquids with a viscosity up to 200 cp. No Drip Siphon Fed Atomizing Nozzles are siphon or gravity fed for non-pressurized applications.  Read More >>

Why No Drip Atomizing Nozzles?

When spraying any type of liquid, post spray liquid flow can cause big problems. Unwanted drips can ruin product finishes on painted or coated surfaces. In addition, excess liquid flow wastes precious resources such as expensive coatings, chemicals or water. EXAIR's no drip atomizing nozzles are ideal where no post-spray drip is permissible. When the compressed air supply is shut off, the no drip nozzle positively seals off the flow of liquid eliminating the possibility of drips. They can be used in any situation that our standard atomizing nozzles can be used, including Siphon Fed applications. Unlike some manufacturers, there's no need to run a separate air line to control the no drip mechanism. The same compressed air used to combine and atomize liquid in a variety of patterns is used to open a valve allowing liquid to flow. That makes these ideal for use with EXAIR's money and energy saving EFC.

 EXAIR's no drip nozzles do not change flow rates from standard atomizing nozzles. Operations that require up to 180 cycles per minute can be achieved. Minimum operating air pressure of 30 PSIG (2.1 BAR) required.


Droplet Size and Spray Angle

Droplet size can be adjusted by varying either the air or liquid pressure. An increase in air pressure or decrease in liquid pressure will generally produce a smaller droplet size. The Spray Angle is the trigonometric angle created by the width of the spray pattern and the distance at which it is measured.
