ChicagoPressureAir Fans are at
work in asmany diverse appli-
cations as they are in locations
throughout theworld. Clean air
applications include combustion
air, air drying, primary air
ejectors, andproduct cooling.
This fan canhandlenumerous
materials inpneumatic conveying
systems. The PA fan is ideal for
corrosiveexhaust, air pollution
systems and chemical processing.
By adding ceramic tileor
chromiumcarbidewheel and
housing liners, Chicago’s PA fans
easily handle abrasivematerials.
Inparticular, fanswith ceramic
tile liners are extremely effective
inpulverized coal applications,
handling up to250 grains per
cubic feet of air. For corrosive
gases, a stainless steel wheel
andhousing is available, or a
lower cost rubber-lined, mild
steel housingwill often fulfill
the requirements.

PRESSURE AIRFANS
Wheel Designs to
Meet Specific Volumes
and Pressures
ChicagoBlower’s Design2300
radial bladedwheel is available
in single anddoublewidth
designs in sizes from20" to100".
Diameters are variable to115%
of nominal withwheel widths
available from40%to115%.
As a rule, wheel widthdictates
air volumewhile thediameter
controls thepressure. By varying
thewidth anddiameter, over-
lapping performanceenvelopes
are created andoptimum
efficiencies are realized.
Chicago’s Design4900 radial
bladedwheel is available in single
width sizes from
34" to100". The
wheel’s narrowwidth
blades and slightly
conical sideplatemake
it our lowest specific
speed custom fan.
Standardwheels are constructed
fromASTMA606, A242 and
A588 alloy steel capableof
800°F. Optional stainless steel
wheels are rated to1000°F. All
PA fanwheels aredynamically
balanced. Thepressure range
extends to108"wg and volumes
to440,000 CFM.
