Airfoil<br />
The Airfoil blade design delivers the highest static<br />
efficiencies of all centrifugal fans. The <strong>Clarage</strong> AF,<br />
AFM, and RHM fan models are the perfect choice<br />
in applications requiring heavy-duty fans operating<br />
at low energy cost.<br />
Since the <strong>Clarage</strong> airfoil fan can be used in applications<br />
where particulate is present, our design<br />
is used extensively in many different industries. A<br />
solid nose bar and blade liners can be built into<br />
each blade and provide maximum abrasion resistance<br />
along the leading edge and on high wear areas of the<br />
blade. Blades are also reinforced to meet the exact<br />
duty requirement.<br />
The skilled craftsmen in <strong>Clarage</strong>’s in-house manufacturing<br />
facility take pride in building the best airfoil<br />
fan in the industry.<br />

applications requiring high<br />
static pressure<br />
> Full blade and housing<br />
liners available for severe<br />
duty applications<br />
> Hard surface weld beads<br />
are added to break up<br />
abrasive dust patterns<br />
Backward Curved<br />
Single Surface Airfoil<br />
The Backward Curved Single Surface Airfoil achieves<br />
static efficiencies slightly less than an Airfoil. <strong>Clarage</strong><br />
engineers can assist you in selecting between the<br />
RHS, BCS, and CHS styles to find the perfect fit to<br />
achieve your performance criteria.<br />
Applications requiring higher static pressure impose<br />
extreme stress on the wheel components due to high<br />
tip speeds. The <strong>Clarage</strong> Backward Curved wheel is<br />
designed specifically to meet this challenge. When<br />
required, these fans can also be equipped with full<br />
or partial blade liners for severe duty applications.<br />
<strong>Clarage</strong>’s unique “S” shaped blade profile delivers<br />
higher efficiencies with the ruggedness of the radial<br />
tip fan. Typical applications include coal-fired boilers,<br />
electric arc furnaces and cement kilns.<br />

Backward Inclined<br />
The Backward Inclined BIM fan is a straight bladed<br />
design that is ideally suited for clean and abrasive<br />
airstreams. The high wear and abrasive nature of<br />
Induced Draft and Kiln Dryer fans can wear the<br />
blades of a fan very quickly. The Backward Inclined<br />
design sheds particulate and can be designed with<br />
high brinel wear liners to prevent erosion of the<br />
impeller.<br />
> Designed to shed particulates,<br />
such as dust, in the airstream<br />
> Suited for both clean and<br />
dirty airstreams<br />
> Great for all temperatures<br />
<strong>Clarage</strong>’s custom engineered Backward Inclined fan<br />
model BIM can achieve the highest levels of efficiency,<br />
and are perfect for high static pressure applications.<br />
Whether you are exhausting high temperature, dirty, or<br />
corrosive gases, we can design the fan at the peak<br />
of efficiency to meet your needs.<br />
Modified Radial<br />
The <strong>Clarage</strong> HMF Modified Radial wheel design<br />
is a slightly backward inclined shrouded radial. It<br />
combines the best of the Radial design with the<br />
efficiency of the BI design. A slight backward<br />
incline to the blades combined with the radial<br />
blade design makes it the best solution for dirty<br />
or particulate-laden airstreams.<br />
> High efficiency design ideally<br />
suited for material handling<br />
> Designed to withstand the most<br />
demanding environments<br />
Designed for coal conveying, the HMF is available<br />
with blade liners for wear protection and a variety<br />
of specific speeds to meet all design requirements.<br />
Whether you are conveying pulverized coal, sand or<br />
steel sinter, the HMF can stand up to the toughest<br />
environments.<br />

First choice for severe duty<br />
applications<br />
> Self-cleaning flat radial blade<br />
design<br />
> Sustains very high tip speeds<br />
to meet high static pressure<br />
needs<br />
Radial Blade<br />
The <strong>Clarage</strong> Radial Blade XLR fan is the first<br />
choice for severe duty applications, especially<br />
those involving hot, abrasive or sticky particulate.<br />
The flat radial blade design is self-cleaning, which<br />
makes it very cost effective by reducing downtime<br />
in critical and continuous service applications.<br />
<strong>Clarage</strong>’s Radial Blade fan is designed to sustain<br />
very high tip speeds to meet your high static<br />
pressure needs.<br />
The radial blade wheel shown reveals<br />
the narrow blade tip width for developing<br />
high static pressures, and straight radial<br />
design for excellent resistance to material<br />
build up.<br />
> Rugged design makes it suitable<br />
for severe duty service areas<br />
> Full blade and housing liners<br />
are available for the most<br />
abrasive applications<br />
Radial Tip<br />
<strong>Clarage</strong> Radial Tip fans are used extensively in<br />
many industries. The ruggedness of our RT and<br />
RTC radial tip wheel makes it especially suitable in<br />
severe duty service areas, such as cement plants,<br />
flue gas recirculation and boiler Induced Draft fans.<br />
It can be armored with full blade and housing liners<br />
for the most abrasive applications.
Variable Pitch Axial<br />
Axial fans are ideally suited for high volumes of<br />
air at lower static pressures. <strong>Clarage</strong>’s Variable<br />
Pitch axial design uses multiple blades attached<br />
to a center hub to adjust air performance while<br />
in operation. The highly engineered center hub<br />
linkages are designed to rotate the blades open<br />
and closed to increase or decrease the airflow of<br />
the system without ever having to shut the fan off.<br />
Variable Pitch Axial Fans are perfect for Induced<br />
Draft and Forced Draft Fans in the power and<br />
mining industry. As airflow requirements change in<br />
the system, let the fan do the work. The seamless<br />
transition from low to high flow allows the system<br />
to adjust while the fan is running.<br />
State-of-the-art engineering and tight machining<br />
tolerances on the hub components leads to years<br />
of maintenance-free operation on all <strong>Clarage</strong> Variable<br />
Pitch Axial Fans. Whether you need a 24" fan to<br />
feed an oxidizer or an 8m fan to run a wind tunnel,<br />
<strong>Clarage</strong> has a solution for you.<br />
Adjustable-at-Rest Axial<br />
The Adjustable-at-Rest Axial Fan utilizes the same<br />
design as the variable pitch. The complexity of the<br />
adjustable center hub is removed and the blades<br />
are locked into place. Simply shut the fan down to<br />
make adjustments to the blade angle for increasing<br />
or decreasing the airflow. Hooking the system up to<br />
a damper or VFD can also allow for easy adjustments<br />
to the airflow.<br />
> Automated adjustments can<br />
be made to the blade angles<br />
while the fan is running<br />
> Available in six blade designs<br />
to fit the fan to the exact duty<br />
> Engineered with high quality<br />
components for years of<br />
dependable, low maintenance<br />
operation<br />
> Manual adjustments can be<br />
made to the blade angles<br />
while the fan is at rest<br />
> Highly engineered, lower cost<br />
alternative<br />
The lower cost and simpler design of the Adjustableat-Rest<br />
impeller is ideal when cost or maintenance<br />
is a major concern. <strong>Clarage</strong>’s CFD, FEA and modeling<br />
capabilities allow us to custom engineer the<br />
exact fan configuration that will best accommodate<br />
your needs.

Tubular Bases<br />
<strong>Clarage</strong> recognized that in order to achieve high<br />
design resonance levels, the stiffness of the base<br />
was key. That is why <strong>Clarage</strong> engineers designed<br />
a reinforced tubular base with a rectangular crosssection<br />
and thick tube-wall. The resulting base<br />
provides trouble-free fan operation – even with<br />
motors in excess of 800 HP – and gives the fan<br />
engineer or user more options for the foundation design.<br />
So whether you require 1,000,000 or 3,000,000<br />
lbs. of horizontal stiffness, we have a solution to<br />
meet your exact design requirements.<br />
Two-Stage<br />
Fan System<br />
<strong>Clarage</strong> is a leading supplier of two-stage fans<br />
for process applications. A two-stage fan can<br />
accommodate applications involving corrosive<br />
gases and particulate loaded gas streams where<br />
compressors are not suitable. Two-stage fans<br />
also operate at reduced speeds to produce the<br />
same pressures as single stage fans, resulting in<br />
reduced wear rates. One driver and one foundation<br />
result in a smaller footprint and reduced installation<br />
and maintenance costs. <strong>Clarage</strong>’s two-stage fans<br />
are ideal for high pressure applications, such as<br />
compressor superchargers, air pollution control<br />
systems, flue gas recirculation, fluidized beds,<br />
boilers, and high pressure chemical processing.<br />

Heavy Duty Dampers<br />
Variable inlet vanes are highly efficient at maintaining<br />
volume control, offer more control than box dampers,<br />
and lower part load power consumption. These radial<br />
inlets have control dampers that can be used<br />
with open inlet fans or fans with inlet boxes. For<br />
high temperature fan applications, such as ID fan<br />
service, the mechanism can be isolated from the<br />
gas stream.<br />
External linkage radial vane dampers are also highly<br />
efficient at maintaining volume control. Having the<br />
bearings and linkage outside of the casing promotes<br />
longer life and allows for operation in particulateladen<br />
applications. Routine maintenance can also<br />
be performed on the bearings and linkage while the<br />
fan is in operation.<br />
<strong>Clarage</strong> designs and manufactures both opposed<br />
blade (MLOB) and parallel blade (MLPB) multi-louver<br />
dampers. MLOB dampers are commonly used on<br />
fan outlets. MLPB dampers, when used on fan inlet<br />
boxes, provide increased fan efficiency at reduced<br />
loads. Rugged construction is a featured quality of<br />
these types of dampers.<br />
