If you've ever cleaned around the house (and who hasn't?),
you're probably familiar with atomized liquid spraying...it's what happens
when you squeeze the trigger on that bottle of cleaner that breaks down the
stove top grease in the kitchen and the ring-around-the-tub in the bathroom.
There's a variety of industrial and commercial applications
that require an atomized liquid spray too...applications that are beyond the
scope of an operator with a trigger-operated spray bottle. That's where EXAIR Atomizing Spray Nozzles come in.
We have three types: Internal Mix, External Mix, and Siphon Fed. Depending on what you want
to spray, and how you want to spray it, one of these is likely going to work
better than the others for you. Today, we're going to examine the Internal Mix Atomizing Spray Nozzles.
Benefits:
Better mist: Because the liquid &
air come together inside the air cap, this results in very fine atomization.
Range of adjustment: Regulating either the
liquid or air pressure supply will change the flow rate AND the flow pattern,
giving each individual nozzle a wide performance band. The needle valve
can "fine tune" the flow and pattern with even greater precision.
Area of coverage: With five patterns (Narrow
or Wide Angle Round, Flat Fan, Deflected Flat Fan, and 360° Hollow Circular)
and 72 distinct models to choose from, you can get spray patterns from
2" (1/8 NPT
Narrow Round Model AN8010SS) to 13 feet (1/2 NPT 360° Hollow
Circular Model AT5010SS.)
Flow rate: Again, because of the many
models available, you can get from 0.6 gallons/hour (Model AN8010SS
again) to 264 gallons/hour (1/2
NPT Wide Angle Round Model AW5030SS.)
Features:
No-Drip option: The standard Models have a
needle valve, which, as mentioned above, gives you the ability to make minute
changes to the flow rate & pattern. If the application calls for
rapid on/off control, or the chance of an errant drip after flow is not
stopped might be a problem, the needle valve can be replaced with a No-Drip
assembly. This positively shuts off liquid flow, at the exit of the
liquid cap, when air pressure is secured.
Easy installation: All of our Atomizing Spray
Nozzles have female NPT (1/8, 1/4, or 1/2) ports. The 1/8 and 1/4 NPT
models can be adequately supported - and positioned - with a Stay Set Hose,
and all models (even the 1/2 NPT) can be used with an appropriately sized
Swivel Fitting. If you want to use your own tubes or hoses, we've got
"clip-in" style Mounting Brackets.
Interchangeability: The only difference
between any model of the same-size Atomizing Spray Nozzle is the Liquid
and/or Air Cap. If your application's liquid spray requirements change,
or vary, you don't need to replace the whole nozzle; just one (or in some
cases, both) of the caps.
Internal Mix Atomizing Spray Nozzles are
ideal for liquid viscosity up to 300cP and in situations where the liquid is
(or can be) pressure fed.
