The Series 900 Industrial Fans manufactured by Twin
City Fan & Blower are well suited for installations
involving exhaust, material conveying, pollution control, air circulation, and a variety of other industrial
applications.
The typical performance characteristics for different
impellers offered in Series 900 fans are illustrated
on page 3. It should be noted that all impellers
essentially have overloading characteristic type brake
horsepower curves; however, type RBA impellers have
this to a lesser degree than other types.
RBO
Arrangement 8
Twin City Fan & Blower certifies that the Series 900 Model
RBO/RBR/RBA/RBW fans shown
herein are licensed to bear the
AMCA Seal. The ratings shown
are based on tests and procedures performed in accordance
with AMCA Publication 211 and
comply with the requirements
of the AMCA Certified Ratings
Program.
While the general pressure characteristic curve is
similar for all Series 900 impellers, the RBA type
impeller is considerably more efficient than other
Series 900 impellers. Therefore, the RBA impeller is
the first choice where brake horsepower savings are
important, but the RBA impeller is limited to handling
relatively clean air or gases.
Efficiency is critical in most applications, and it is
important that the fan size is selected so that it will
operate at or near its maximum efficiency point. This
is particularly important with the units that have lower
efficiency in general, such as the RBO and RBW
impellers.
Twin City Fan & Blower offers a complete series of
impellers to meet the needs of most industrial process and material handling applications. Each impeller
is statically and dynamically balanced on electronic
equipment prior to being assembled in the fan. In
addition, each unit is run at or near operating speed
after assembly and the balance is fine-tuned as a
complete assembly.

* Note: RBR is standard on size 926 and larger Class 32 fans.
Series 900 fan housings are constructed in all usual arrangements and conform to AMCA Standard 2404-72 (Drive
Arrangements for Centrifugal Fans). The fan sizes and impeller diameters conform to AMCA Standard 2402-66 (Sizes for
Industrial Centrifugal Fans).
AMCA does not have a standard for industrial fans designating class of operation. Twin City Fan & Blower offers
three basic categories, based on performance, of industrial
2
fans. Two of the categories are shown in this catalogue:
1. Class 22 – suitable for applications involving performance
to approximately 5470 Pa; and
2. Class 32 – for performance to 7950 Pa.
A separate supplemental catalogue (Catalogue 911) shows
the third category: Class 45 – high pressure fans capable of
reaching performance of approximately 11190 Pa.
Twin City Fan Catalogue M902
ImpellerTypes
RBO Industrial Radial Paddle Impeller: The open
type radial paddle impeller design is extremely rugged using heavy-gauge steel components which
are jig assembled for accuracy and consistency. All
impellers are welded with care to insure the maximum in strength and reliability. RBO impellers are
suitable for general handling of coarse, sticky, heavy,
and/or abrasive materials.
RBR Industrial Radial Paddle Impeller: The RBR
impeller is similar to the RBO, with the addition of
end rings. RBR construction is standard on size 926
and larger Class 32 fans. RBR impellers are suitable
for general handling of coarse, sticky, heavy, and/or
abrasive materials.
RBO / RBR
RBA
RBW
RBP
RBW Industrial Radial Backplate Wool Impeller: The
RBW impeller is constructed to prevent paper shreddings, threads from buffing system exhaust, and
other similar matter from hanging up on and wrapping around the spiders and blades. Applications
include long, stringy or fibrous materials.
RBA Industrial Radial Air Handling Impeller: The
RBA impeller is a more efficient type of impeller and is used when handling relatively clean air,
fumes, vapor exhaust, and air with a light contaminant. The impeller is constructed with heavy-gauge
blades welded to both backplate and front ring.
RBP Industrial Radial Paper Handling Impeller: This
modified RBW impeller features trapezoidal gussets
for the extra rugged construction necessary when
handling corrugated paper trims, fibrous material,
metal trim, and other high impact loading material. A
paper deflector cone over the face of the hub helps
prevent wrapping of paper around the hub or leading
edge of the blades.
Rotatable and Reversible Configuration
The table on page 2 identifies fans that are rotatable or reversible. A fan available in a rotatable
configuration indicates that the fan can be rotated
in the field to any of the standard discharge locations. A fan available in a reversible configuration
indicates that the impeller rotation can be changed
in the field from a clockwise to a counterclockwise
direction or vice versa. This is possible only on
rotatable housings and requires the impeller housing
to be removed and reversed. Consult the factory
before reversing a fan. See the chart on page 5 for
specific configurations and their designations.
All RBP fans are supplied with bearing stop blocks
and a relieved inlet transition. The relieved inlet transition smooths the flow of paper trim and similar
material through the fan. Breaker tabs are offered
as an option on the relieved inlet transition to assist
in the breakup of material. Due to the nature of the
applications, RBP Class 32 construction is limited to
5470 Pa and RBP Class 45 construction is limited
to 7950 Pa. Use RBW performance curves for RBP
fans. The RBP fan is not AMCA licensed.

Arrangements
Arrangement 1
Arrangement 1 fans are available in either direct
drive (see Arrangement 8 below), or belt driven installations. The belt driven configuration allows the
motor to be mounted in any of the four standard
motor positions shown on page 5. The choice of a
belt driven installation provides greater performance
flexibility with the use of belts and sheaves of differing sizes.
Arrangement 8
Arrangement 8 fans use a fan shaft and motor
direct coupled via a flexible coupling. The integral
motor subbase is fabricated of heavy gauge steel
and securely reinforced for rigidity. Twin City Fan
& Blower can supply impellers in a variety of diameters and differing widths to give the greatest
efficiency for any given application. If desired, an
Arrangement 1 fan can be set up for direct drive.
This requires a concrete motor pedestal to be built
in the field.
Arrangement 9
Arrangement 9 fans include a motor slide base
mounted on the side of the motor pedestal. The
motor and drive can be installed at the factory or
field installed. Class 22 fans up to size 929 are offered in Arrangements 9A (shorter pedestal for small
motors) and 9B (longer pedestals for larger motors).
Maximum motor frame sizes for Arrangement 9A
and 9B are listed in the table on page 5.
Unless otherwise specified, the motor will be installed on the left (L) side of the pedestal on CW
fans and on the right (R) side on CCW fans.
Arrangement 9F
Arrangement 9F (floor mount) fans are recommended
when a packaged unit is desired, but required motors are too large to be mounted on the side of the
bearing pedestal. In this arrangement, the base is
extended to facilitate motor mounting in a horizontal
position similar to an Arrangement 1 fan. This arrangement is preferred over Arrangement 9 when larger
kilowatt motors are being employed.
Unless otherwise specified, the motor will be installed
on the left (L) side of the pedestal on CW fans and
on the right (R) side on CCW fans. Arrangement 9F
requires a separate subbase when vibration isolation
is required.
Arrangement 10
Arrangement 10 fans are suitable for roof or outdoor
installations. A weather cover, as shown, provides
complete weather protection for motor, shaft, bearings, and drives. This arrangement is limited to
Class 22, sizes 905 through 919. Maximum motor
sizes allowable in this arrangement are listed in the
table on page 5. Larger fan sizes in this arrangement, or larger motor sizes for smaller fans, may
be available on special request from the factory. All
usual accessories are available in this arrangement.

Direction of rotation is determined from the drive side of the fan.
On single inlet fans, the drive side is always considered the side opposite the fan inlet.
Direction of discharge is determined in accordance with the diagrams shown above. Angle of discharge
references the horizontal axis of the fan, and is designated in degrees above or below that reference axis.
On fans inverted for ceiling suspension or side-wall mounting, the direction of rotation and discharge is
determined when the fan is resting on the floor.

Accessories
Access Doors
Bolted and quick-opening access doors are available for easy access to the fan interior for inspection or cleaning. All access doors are gasketed and
are constructed with either evenly-spaced studs
or heavy duty hinges and handle-type nuts which
require no tools to open. Raised bolted access
doors are available for use where insulation is being
applied to the outside of the fan.
Inlet Bell
Quick-Open
Access Door
Bolted
Access Door
Raised Bolted
Access Door
On installations with an open inlet (no ductwork
at the inlet of the fan), a streamlining inlet bell is
required to achieve the catalogue performance.
Outlet Dampers
Due to the performance characteristics of industrial
fans, a damper on the outlet of the fan is a very
efficient way to control volume.
Outlet Dampers
Inlet Bell
An outlet damper can be used to reduce the power
consumption of a fan operating at high temperatures or a fan operating in low density gas streams.
During a cold startup, the outlet damper begins in
a closed position and is opened gradually as the
fan reaches operating temperature. This allows for
the use of a smaller motor sufficient to handle the
duty at higher temperatures.
Twin City Fan & Blower offers two basic styles of
outlet dampers: Type 1 is made of single surface
blades suitable for clean air applications, pressures
to 620 Pa and temperatures to 148°C; Type 2
has double surface airfoil blades for abrasive type
applications, pressures to 995 Pa and temperatures
to 426°C. Both types of dampers are available with
opposed or parallel blades and can be manually
operated or set up for automatic operation.
Inlet Vanes
For reduced flow situations with relatively clean air,
inlet vane type dampers are available to maintain
fan efficiency. The inlet vanes are external type
attached to the inlet of the fan. Standard construction inlet vanes are suitable in applications up to
148°C. High temperature inlet vanes are also available for temperatures up to 315°C.

Accessories
Inlet Boxes
An inlet box is designed to minimize pressure drop
and airflow losses. Inlet boxes are recommended
for applications where uniform flow is difficult to
obtain due to limited space or where the air must
enter the fan at an angle. Inlet boxes can be
either detachable or integral to the fan. This option
is available with an inlet box damper to provide
increased airflow control.
Drains
A pipe coupling can be welded to the lowest point
in the housing scroll to allow wash water or condensation to drain.
Inlet Box
Drain
Shaft Coolers
Where high temperatures are encountered, the aluminum shaft cooler is recommended for dissipating
heat and protecting bearings from the high temperature atmosphere.
Shaft Seals
The standard shaft seal is a non-asbestos type,
sandwiched between two plates and the fan housing, providing a seal for most materials being handled. A variety of special seals, including mechanical type stuffing boxes, is available for gas-tight
applications requiring more positive protection.
Shaft Seal & Saft Cooler
Spark Resistant Construction
Three fan constructions are available for spark
resistance. The materials used in the construction
of these fans minimize the potential of sparks being
generated by striking or rubbing components within
the airstream.
Type A –All parts of the fan in contact with the
air or gas being handled are made of
nonferrous material. (Aluminum impeller
construction is limited to 120°C.)
Type B –The fan has an entirely nonferrous
impeller and nonferrous ring around the
opening through which the shaft passes.
(Aluminum impeller construction is limited
to 120°C.)
Type C –The fan is constructed so that a shift of
the impeller or shaft will not permit two
ferrous parts of the fan to rub or strike.
In applications where aluminum is not
suitable, impellers constructed of Monel
can be furnished for temperatures up to
538°C.
Other Accessories
A large number of other appurtenances and accessories is available from Twin City Fan & Blower,
including:
• Belt guards – standard and OSHA type
• Split housings
• Shaft and bearing guards
• Couplings and coupling guards
• Impeller liners
• Scroll liners
• Weather covers
• Inlet and outlet screen
• Special material construction (stainless steel,
Monel, etc.)
• Special coatings and finishes
• Insulation pins
• Abrasion resistant construction
• Common bases with and without isolation
• Breaker tabs are offered on Series 900 RBP
fans as an option on the relieved inlet transition.
These tabs assist in the breakup of material as
it enters the fan.
Notes:1.The user must electrically ground the fan.
2.Standard spark resistant alloy is aluminum.
3.Bearings must not be placed in the air
or gas stream.
