WindJet® Air Knives
Unique design provides more controlled, efficient and reliable blowing and drying
Benefits
• Unique leading edge delivers a more controlled air stream
• Edge extends 1/8” beyond the air slot along the length of
the knife and directs the air flow out of the knife in a
straight stream
• Eliminates spotting and blotching
• Using the Coanda effect and air entrainment principles,
the air stream is maintained further downstream and total
air volume is increased
• Tear-drop shape increases air velocity to exiting air
• Easy set-up
• Extended edge provides a visual guide for accurate
positioning of the knife
• Leak-proof end cap gaskets to prevent air leakage
• Corrosion-resistant finish
• Durable, long life span
• 3” flanged air inlet; threaded mounting insert
• Two air slot sizes: .040” and .060”
• Available in 6”, 12”, 18”, 24”, 30” and 36” lengths;
custom lengths available

Effective drying in holes and crevices
Benefits
• Provides a high velocity air stream into holes and
indentations in irregularly-shaped parts
• Used in conjunction with air knife packages for complete
drying; built-in mounting spacer simplifies positioning of
the unit in a mounting bracket
• Anodized aluminum construction for good wear and
corrosion resistance
• Three orifice sizes: .5”, .75” and 1” (12.7, 19 and 25.4 mm)

• Three-phase, dual-frequency
and multi-voltage motor
versions available for
worldwide applications
• Filter monitoring gauge
helps protect blowers
from overheating due
to clogged filter elements
Blower Performance and Operation
• Operating the blowers at high altitude decreases their
maximum pressure duty rating. Contact your Spraying
Systems Co. sales engineer for more information
• The exhaust air temperature of the blowers increases
with increasing duty. To prevent danger of burns, access
to these pipes should be limited, guarded or marked
“Danger Hot”
• Models without explosion-proof motors should not pump
combustible gases or be used in combustible ambients
• A clogged filter can overheat the blower. Filter element
should be replaced at a maximum pressure drop
of 10 to 15" (254 to 381 mm) H2O

• The performance data shown in this bulletin were
determined under the following conditions:
– Line voltage: 60Hz; 208 - 230V or 480V
for three-phase units
– Units in a temperature stable condition
– Delivery measurements made with input port throttled
– Test conditions: Inlet air density at 0.075 lbs. per cu. ft.
[68°F (20°C), 29.92 in. Hg (14.7 PSIA)]
– Normal performance variations on the resistance curve
within ±10% of supplied data can be expected
– Pictorial and dimensional data is subject to
change without notice

Blower Assembly Components
Air Inlet Filter
Keeps particles from entering the blower,
ensuring smooth operation and trouble-free
service. Filters come with all blower
assemblies. Standard assemblies
come with polyester
or HEPA filters.
Pressure Relief Valve
Protects the blower from
excessive duties.
Mounting Flange
Pressure Gauge
Monitors inlet filter restrictions.
Fittings
Required for connecting
components to the blower.
Vibration Dampener (Not Shown)
Isolates vibration, shock and noise.
Outlet Mounting Adapter
Incorporates the pressure gauge
and pressure relief valve inline
with out-going tubing. This saves
you the necessity to custom-build
such an adapter.
Regenerative Blower
Filter Monitoring Gauge
Attaches directly to filter shroud.
Indicates how much life the filter
element has left.

WindJet® Air Knife Package Accessories
Ensure efficient air delivery from the blower to the knives
All necessary accessories for mounting and implementing the product into your applications
are included in the air knife package. Accessories vary by package. All items are rated
for a minimum of 225°F (107°C).
Elbows
Manifolds
To help reduce pressure losses
in the system, we offer both
45° and 90° rigid elbows in
3" and 6" (76.2 and
152.4 mm) diameters.
Constructed from high-strength,
high-temperature thermo plastic,
manifolds allow a single air outlet
on the blower to be divided
for multiple knives in various ways.
Mounting Brackets
• Y-divider: Allows for single inlet to be divided into two
outlets. Available in both 3" and 6" (76.2 and 152.4 mm)
inlet OD, with 3" (76.2 mm) outlet OD.
These 100% stainless
steel adjustable brackets
are used for conveniently
mounting air knives. Two
specialized mounting plates
connect to each end cap
on the air knife.
Request data sheet 50040 for dimensions.
Flexible Tubing
High temperature, steel-reinforced
flexible tubing available in 3" and
6" (76.2 and 152.4 mm) diameters
and comes in lengths of 10' (3 m).
To attach the flexible tubing, we
offer high-torque, worm-gear clamps.
Couplings
Unique, easy to use 3" and 6"
(76.2 and 152.4 mm) couplings
— stainless steel outside,
high temperature silicon
rubber inside. The couplings
compress for use between any rigid
connections to prevent air leakage and to add support for the
connections. They feature a single built-in clamp that you
tighten by hand; no special tools are necessary.
• 3-port: Allows for a single inlet to be divided into three
outlets. Available in both 3" and 6" (76.2 and 152.4 mm)
inlet OD, with 3" (76.2 mm) outlet OD. Designed with
mounting holes for support.
• 4-port (pictured above): Allows for a single inlet to
be divided into four outlets. Available in both 3" and 6"
(76.2 and 152.4 mm) inlet OD, with 3" (76.2 mm) outlet OD.
Designed with mounting holes for support.
Not available in stainless steel.
Request data sheet 50773 for additional dimensions
of manifolds.
Stainless steel manifolds also available.
Request data sheet 50774.
Noise Reduction Options
Muffler: Reduces noise by
5 to 8 dBa and removes high
frequency sound associated
with all blowers.
Sound Enclosure (shown):
Insulating hoods reduce noise
by 10 dBa. Metal construction
for easy washdown.
