Noise Reduction & Cost Savings
WindJet® Air Products
Improve Process Control
Our air products convert a low-pressure volume of compressed air into
a targeted, high-velocity concentrated stream, flat fan or curtain of high-impact air.
This creates a better quality air pattern than open pipes, drilled holes, and many
other air nozzles. That means dependable, repeatable performance that
can improve your process.
Reduce Noise
Noise from compressed air is one of the biggest environmental hazards in the workplace
today. Using air products can reduce the perceived noise from compressed air
by more than 50 percent. The table below provides an example of potential noise reduction from WindJet 707 or 727 nozzles. For actual noise levels on each product see the
sound level chart on page 6.

Save on Compressed Air Costs
Compressed air is an expensive utility. A properly designed and maintained air
system can save hundreds or even thousands of dollars each year in
operating expenses. So in addition to improving your processes and making your
work place quieter, air nozzles can pay back their cost many times over.
The following tables focus on three primary areas: impact, capacity and coverage.
Each table summarizes the potential savings by reducing air consumption, using various
WindJet air products featured in this catalog. It’s important to note that each
of these tables single out specific, but very common, problem areas. Your application
may require a combination of one or more of these to operate at a lower cost and
higher efficiencies, while maintaining the proper blow-off and drying requirements
for your product. Your local Spraying Systems Co. sales engineer can assist
you in designing a system that addresses all of your requirements.

Technical Data
Key Considerations for Selecting
There are four main characteristics that should be considered when selecting an air nozzle.
They are effective spray coverage, sound level, lineal impact force, and specific impact force.
Each characteristic plays a role in choosing the most effective nozzle for a given application.
Effective Spray Coverage
Effective Spray Coverage at 40 psig (2.8 bar)
Selected Air Nozzles
Spray Coverage
Spray coverage is described as the width of the spray
pattern for a flat fan air nozzle. Effective spray coverage
is the width of the fan, which comprises a minimum spray
force measurement. This coverage can be used as a guide
for spacing nozzles. Effective spray coverage varies for
different types of air nozzles. The graph shows a selected
variety from each of the families. While effective coverage is relatively consistent above 40 psig (2.8 bar), it may
decrease at lower pressures. In general, effective coverage
increases as distance from the nozzle increases.

Sound Level
Capacity and nozzle design both affect noise levels.
In general, higher flow rates increase noise levels.
Other factors include air pressure and obstructions
in the nozzle’s path. Sound level tests shown on the
accompanying graph were conducted by blowing into
an open space with no reverberation. Spraying the
nozzle against objects will increase sound levels.

Specific Impact
Lineal Impact
There are two types of impact to consider when selecting
air control nozzles: lineal impact and maximum specific
impact. Both lineal and specific impact increase with
pressure. When capacities are the same, a nozzle with
a smaller coverage will have greater impact than one
with a wider coverage. Lineal impact indicates relative
force per unit distance across the spray width. Flat spray
patterns have fairly uniform impact distribution across
the effective spray coverage. Spacing of nozzles in
a header according to the effective spray coverage
will provide consistent lineal impact across the entire
length of the target surface. Maximum specific impact
is a direct indication of spray intensity applied to a surface.
It provides maximum force per unit area information,
which can be used to compare spray effectiveness
under various conditions.

WindJet Low Flow Air Knives produce a high velocity,
constant air stream for optimal performance of your drying
and blow-off process. Compressed air flows through an
inlet (A) where it is directed to the orifice. The primary air
flow exits the thin slotted nozzle orifice across the length
of the knife (B) creating a uniform sheet of air. For added
force, secondary air is entrained along the edge of the
knife (C). The end result is a highly uniform, constant air
stream with hard-hitting force.

For conveniently mounting air knives, these
adjustable brackets include two specialized
mounting plates that connect to each
end cap on the air knife.
We offer high temperature, steel reinforced
flexible tubing and stainless steel rigid tubing
options. For the flexible tubing we also
provide high torque, worm-gear clamps.
Easy to use, stainless steel couplings compress
for use between the air knife and a rigid elbow
or any two rigid surfaces to prevent air leakage
and damage to the air knife. The couplings
feature built-in clamps.
No tools are required.
