No Drip Internal Mix Atomizing Nozzles

Eliminate drips to conserve valuable
liquids and improve product finishes! EXAIR's patented No Drip Atomizing Nozzle
provides the same great performance as the the standard atomizing nozzles with
the added benefit of positive liquid flow stoppage when the compressed air is
shut off.
The No Drip option eliminates the
occurrence of post spray liquid flow that results in unwanted drips that can
mar a finish on painted or coated surfaces. Also, excess liquid loss is
minimized saving on expensive materials like chemicals or coatings. When
the compressed air is shut-off, the No Drip nozzle positively seals off the
flow, eliminating the chance for a drip or lost liquid. Only one compressed air
line is needed, as the line to combine and atomize the liquid also provides the
no drip operation and control.
The No Drip Atomizing Nozzles are
available in (3) types - Internal Mix, External Mix, and
Siphon Fed.
The Internal Mix type operates under
the principle that the air and liquid come together and mix 'internal' to the
nozzle. This type provides the finest atomization and smallest droplet
size. The Internal Mix type of nozzle can be used with liquids up to 300 cP in
viscosity. Both the air and liquid sides are pressure fed. The No
drip Internal Mix Atomizing Nozzles are best for pressure fed applications not
requiring independent air and liquid control.
The No Drip Atomizing Nozzles
are available in (3) sizes - 1/8, 1/4, and 1/2 NPT - to provide a wide range of
flow rates and pattern sizes. The No Drip feature does not impact the
flow rates compared to the standard models. Minimum air pressure
operation is 30 PSIG for the 1/4 and 1/2 NPT, and just 20 PSIG for the 1/8 NPT
models.
Like the standard Internal Mix
Atomizing Nozzles, spray patterns include narrow and wide angle round,
flat fan, deflected flat fan and a 360° hollow circular pattern offering a wide
selection to best meet the application needs.
Operation at up to 180 spray cycles
per minute is possible. Air and Liquid Caps can be switched out to change
the pattern and flow rates.
