Canada Blower Co. now offers high temperature construction on its axial fans.  There are af ew steps of fan heat construction available: 200 F, 725 F, 800 F. High temperature inline fans are ideal for industrial oven and dryer exhaust systems where pressure requirements are minimal and compcat light-weight designs are advantageous.
          
200 F High Temperature Duct Fans come with special heat bearings and a belt drive with increased safety factor.
 
650 F Tubeaxial Fan design involves special belt tunnel cooling system that induces a flow of cooler, ambient air through the belt well and inner tube, cooling the fan's internal components. Depending on temperature requirements, modifications include high-temperature alloy fan wheel, special drive components, and modifications to provide internal ambient air cooling. Fans with ambient air cooling systems handling hot airstreams must have sufficient airflow and be kept in operation until airstream temperatures cool below 120 F to prevent damage to the fan unit.
The Tubeaxial fan ambient air cooling system is only effective while fan is operating.
         
800 F Vaneaxial Fans are designed to operate continuously at temperatures to 800 deg. F, and include an auxiliary cooling fan that forces air through the bearing compartment and exits out through the insulated belt opening taking away excessive heat from the shaft and bearings. A high temperature shaft seal is also standard on this design.
Fans handling hot airstreams must have sufficient airflow and be kept in operation until airstream temperatures cool below 120 F to prevent damage to the fan unit. The Tubeaxial fan ambient air cooling system is only effective while fan is operating.

in the two major types of high temperature fans - centrifugal and axial:
 
Centrifugal Wheels:
 
    * Multiblade forward curve wheel.  This type of wheel is usually specified where there is a necessity for large volumes of flow against low to medium static pressure requirements.  The forward curve blade is that it delivers the same volume of air as either the backward or radial blade wheel, at a lower fan speed, which is important due to wheel stresses at elevated temperatures.  This fan is the most common type used in all types of heat treatment operations except where a buildup of material on the blades could occur, as wheel unbalance would result.

    * Radial Blade, paddle wheel type fans.  This type of wheel is usually specified where there is a necessity for medium volumes of flow against medium to large static pressures. The paddle wheel is considered a self cleaning type of wheel.  It could be used where there are various materials or dust in the air stream.  Due to its structurally strong design, it is used in many heat treatment applications at very high temperatures where maximum fan longevity is desired.
 
Axial Blade Wheels:
 
    * The axial blade wheel is usually specified where there is a need for very large volumes of flows against low static pressure.   Axial wheel like the multi-blade forward curve type wheel could cause an axial fan to deliver different air volumes at the same static pressure, if the total pressure requirement of the fan system was underestimated. This type of fan is ideally suited where a large volume of flow is required with a minimum of duct work and is used extensively for small and large furnaces, such as aluminum annealing.

The key factor in the construction of an
industrial fan is the type of metals and
materials used to produce them. The choice
of materials a􀃡ects the weight, cost,
sanitation, durability, maintenance, and
appearance of the fan. The factor that
determines the types of materials is the
application for which the fan is designed.
Caustic conditions, high operating
temperature, and explosive environments all
play a part in the selection process. The
common types of metals include various
grades of steel, stainless steel, nickel alloys,
titanium, monel, and aluminum.
Industrial Fan Materials Tools
Aluminum
Aluminum is used for the manufacture of the
critical components of fans such as the
housing and wheel. Spark resistant
construction (SRC) is a standard of the Air
Movement and Control Association (AMCA)
when dust, 􀃕bers, gases, vapors, or liquids are
present and may cause explosions.
Aluminum falls under the classi􀃕cation as a

Aluminum falls under the classi􀃕cation as a
SRC material.
Stainless Steel
The characteristics and properties of stainless
steel make it ideal for fan manufacturing.
Austenitic stainless steel grades 304 and 316
are the most used in industrial fan
construction. With the addition of
molybdenum and titanium, stainless steel’s
resistance to corrosion and high temperature
applications is enhanced.
Added to stainless steel’s corrosion and high
temperature resistance are its ductility,
strength, hardness, low maintenance, and
exceptional appearance.
Chapter Six - The Air
Movement and Control
Association
The Air Movement and Control Association
(AMCA) is an organization that originated in
1955 with the combination of the National

https://www.iqsdirectory.com/articles/blower/industrial-fans.html 24/26
1955 with the combination of the National
Association of Fan Manufacturers (NAFM), the
Power Fan Manufacturers Association (PFMA),
and the Industrial Unit Heater Association
(IUHA). The goal of the association is to
develop standardized methods for the
certifying and classifying of heating,
ventilation, and air conditioning equipment.
The AMCA is a not for pro􀃕t organization
whose membership is voluntary. The
majority of reputable fan manufacturers
belong to the association and adhere to its
standards. An AMCA certi􀃕cation can be
achieved by testing a fan following the
approved methods of the AMCA. Once the
test standards are met, an AMCA certi􀃕cation
label can be placed on a fan.
In the area of Spark Resistant Construction
(SRC), the AMCA has three standards:
Type A Type A is the highest degree of
spark resistance and requires all
components in the airstream to be
constructed of aluminum.
Type B Type B requires that the impeller
be constructed of a non-ferrous material
with the use of aluminum in the wheel and
rub ring.
Type C Type C requires a minimum level
of spark resistance and reduced contact
between rotating and stationary

components with the inlet cone and rub
ring being made of aluminum.
