Arrangements
Arrangement 4 Direct Drive
The direct drive Arrangement 4 TCVX AXIFAN® is the logical choice when space is at
a premium or a simple, dependable fan with
minimum maintenance is required. The fan wheel
is mounted directly on the fan motor shaft in this
arrangement for a smaller overall size. Where exact
performance of the system is required, the user can
adjust the blade angle to fine-tune the system and
obtain the necessary flow. The Arrangement 4 TCVX
operating temperatures are limited to the maximum
allowable operating temperature of the motor, usually
105°F. Contact factory for temperatures above 105°F.
Performance tables for direct drive TCVX AXIFAN®
units are located on pages 11 through 18.
Arrangement 9 Belt Driven
The belt driven Arrangement 9 TCVX AXIFAN® is the
perfect choice for applications which require the motor to be out of the airstream. Driven by either a fixed
or adjustable V-belt drive system, the exact point of
rating can be easily achieved. Any future change in
rating can be accomplished through a simple sheave
change or blade angle adjustment. The Arrangement
9 TCVX AXIFAN® is good for operation up to 200°F
as standard. It can be customized to handle even the
most severe conditions. Performance tables for belt
driven TCVX AXIFAN® units are located on pages 19
through 27.
Applications
Ventilation
ATEX
The TCVX AXIFAN® is a logical choice for any ventilation
system, as either a supply
or return fan. It can be ducted or provided with an inlet
bell for open (or unducted)
inlet installations. The ability to fine-tune the system
performance through blade
angle adjustment insures the
user of a highly efficient,
economical, versatile, quiet,
and long-running fan.
The TCVX AXIFAN® is available for explosive environment applications where fans must meet the European
Union’s ATEX Manufacturer’s Directive (94/9/EC). Currently, Twin City Fan & Blower offers fans suitable for
Zone 2 and 22, Category 3 environments with special
modifications including, but not limited to, cast B413
aluminum (LM6 equivalent) impellers and navel brass
rub-rings. Fans modified for ATEX environments are
not AMCA certified.
Industrial Process
Smoke Exhaust/Stairway Ventilation
Consult our website (http://www.tcf.com/industries-applications/applications/ATEX) or contact Twin City Fan
& Blower for further information.
The TCVX AXIFAN® is an ideal component for most
industrial air systems. This unit is designed with a
heavy-duty
housing
and
large
diameter
shaft and bearings for
rugged industrial service. The cast aluminum wheel alloy has
strength qualities far
exceeding
common
aluminum alloys, and
the massive hub section makes the entire
rotating assembly less
sensitive to imbalance.
The TCVX AXIFAN® housing and its accessories can
also be provided in aluminum or stainless steel construction for corrosive applications.

The direct drive TCVX AXIFAN® is the perfect choice
for stairway ventilation. The requirement for stairway pressurization has increased due to more stringent public building codes.
During an emergency exit,
the need to create a positive pressure within the
stairway enclosure ensures
a safe exit way. For this
application, the TCVX AXIFAN® uses a maintenancefree, direct drive motor,
and the blade adjustability
allows fine-tuning of the system to the optimum point
of rating.

BladeAdjustment
How It Works
The patented TCVX AXIFAN® blade design provides
the customer with the ability to modify the blade
angle in order to vary the performance without loosening or removing any hardware.
The resilient O-ring acts like a spring (producing friction between hub and blades so the blade does not
turn during operation), to preload the blade retaining
disc and hub arrangement, while providing a centering
force. It insures a proper fit of blade and hub. The
O-ring also minimizes vibration between the blades
and hub, reducing the potential for material fatigue.
The angle of the TCVX AXIFAN® blades can be adjusted without tools. With the fan wheel in motion, the
friction between the blade retaining disc and the hub
itself is increased due to centrifugal force which holds
the blade firm and prevents any undesired change in
blade angle.

Blade Angles
The blade angle for TCVX AXIFAN® fans ranges from
30° to 50° and is indexed in the area where blade
and hub meet. The ratings displayed in this catalog
indicate the specific blade angle required, and the
blade should be set accordingly.
The fan name tag, supplied on the housing exterior, indicates the CFM, static pressure, and corresponding blade
angle setting for the specified flow rate and pressure.
Blade set at 30° angle
How To Adjust
Blade angle adjustment is a quick and simple procedure and can be accomplished through the fan inlet
when convenient. When access to the wheel is not
available from the fan inlet, the blades can be adjusted through the wheel area access door by hand
or by using our TCVX blade adjusting tool. The wheel
area access door and adjusting tool are provided with
our TCVX AXIFAN® units as standard.
When adjusting the blade angle, care must be taken
not to overload the fan motor. Refer to the TCVX fan
curves or consult your Twin City Fan & Blower representative to assure the fan is properly applied. Further
care must be taken to be sure that all fan blades
are adjusted to the same blade angle, thus insuring
proper airflow characteristics and balance.

Accessories
Inlet Bell
For systems with no ductwork on the fan inlet, it is
advantageous to install an inlet bell to avoid inlet
losses. The inlet bell is a toroidal shape to provide a
smooth entrance to the fan. Inlet bells are flanged and
drilled to mate with the fan’s flanged inlet.
Inlet/Outlet Cone
Transition pieces, called cones, can be provided for
both the inlet and outlet. Cones are provided to adapt
from the fan diameter to the adjacent ductwork diameter. Cones are flanged on both ends and drilled to
mate with the fan’s flange. Cones are available with
an access door if required.
Inlet Bell
Inlet/Outlet Cone
Outlet cones can be applied to transform velocity
pressure into static pressure and improve efficiency.
Companion Flanges
Horizontal Flow
For ease of installation of adjacent ductwork, companion flanges can be provided. Flanges are rolled angle
rings, drilled to match the fan’s inlet or outlet flange.
Variable Inlet Vanes
Vertical Flow
Sound Attenuation
Support Legs
For frequent or continuous volume control, a variable
inlet vane can be provided. Variable inlet vanes are
available for each specific fan size and are bolted
to the fan’s flanged inlet. The vane action during
dampering works to spin the air in the direction of
the wheel rotation, thus resulting in lower power consumption. The vane mechanism is outside of the airstream and is controlled by a single vane lever.
Variable inlet vanes can be set up for manual or
automatic operation. The variable inlet vane’s inlet is
flanged and drilled to accept ductwork or an inlet bell
as the system requires.
Sound Attenuation
Suspension Clips
Belt Guard
For applications requiring quiet operation, custom-built
attenuation packages can be provided on the fan inlet
or outlet. Attenuators are aerodynamically and acoustically matched to the specific system requirements
and are designed to significantly reduce noise while
adding only minor resistance to airflow.
Support Legs
Vibration Isolation
All TCVX AXIFANS® can be provided with spring or
rubber-in-shear isolators. Spring isolators are standard
1" deflection and can be provided for floor mount
or ceiling hung orientation. Flexible connections are
required on fans employing vibration isolation. Avoid
collapsed flexible connections on the fan inlet.
Belt Guard
Available for Arrangement 9 belt driven fans, the belt
guard encloses the motor sheave and V-belts. The
guard is easily removable for inspection and maintenance.
6
Horizontal Flow
For horizontal flow with floor mounting, support legs
are welded to the fan flange with bolt holes aligned
for connection of ductwork.
Vertical Flow
For vertical flow with either floor or ceiling mounting,
support legs are welded to the fan housing for fourpoint support.
Suspension Clips
For horizontal flow with ceiling mounting, four clips
of formed angle are welded to the fan housing for
suspension via ties to the ceiling support structure.
Twin City Fan Catalog AX300
Accessories
Weather Cover
For outdoor installations of Arrangement 9 belt driven
fans, the weather cover completely encloses the motor
and V-belt drive from the elements. Provided with slots
for ventilation, the cover is easily removable for inspection and maintenance. Weather covers are available for
either horizontal or vertical flow fans.
Screening
Safety screening can be provided for installation in the
fan inlet, fan outlet, inlet/outlet cone, or inlet bell.
Clamshell Construction
Clamshell construction provides complete access to the
internal components of the fan for tough industrial systems requiring cleaning and maintenance with minimal
down-time. Manufactured with two large doors running
the length of the fan housing on heavy-duty hinges,
clamshell construction is available on 18" – 60" diameter
fans. A split inner cylinder is standard on all clamshell
fans for easy access to the shaft and bearings.

Housing Door
General Observation
For inspection and maintenance of the internal section
(V-belt drive area) of TCVX AXIFAN® units, a general
observation access door can be provided. Doors are
5" x 5" for the 18" fan size and 8" x 8" for all others.
Doors are gasketed, single-skinned, and bolted in place
to the housing exterior. As standard, doors are located
adjacent to the motor base (for belt driven fans) or adjacent to the motor conduit box (for direct drive fans).
Wheel Area
Similar in size and attachment to the general observation
access door, a wheel area access door is also available.
Wheel area access doors differ from general observation
doors in that they are double-skinned to maintain a flush
surface with the housing interior, thus eliminating the
pressure losses that would result from a single-skinned
door in this critical pressure developing area.
Shaft Seal
To limit the air entering the inner cylinder and avoid
contact of airstream contaminants with the bearings and
V-belt drive, a shaft seal can be provided. The shaft seal
consists of a non-asbestos rubbing ring at the wheel
end of the inner cylinder held in place by a cover plate.
Note that a shaft seal does not make the inner cylinder
gas-tight.
Discharge Cap
Spark-Resistant Construction
Discharge Cap with Wind Band and Butterfly Damper
All TCVX AXIFAN® units can be provided with a discharge cap for rooftop mounting. Discharge caps are
designed for vertical discharge with a backdraft damper
to seal out the weather when the fan is shut off. There
is a minimum flow rate required in order for the damper
blade to fully open. See page 10.
Belt driven TCVX AXIFAN® units are available with
spark-resistant construction. Various grades of spark resistance are as dictated by AMCA: Types A, B, and C.
Curb Cap
TCVX AXIFAN® units can be supplied with a base (curb
cap), attached to the fan’s flange for curb mounting. The
combination of a curb cap and discharge cap creates
an upblast-style power roof ventilator (see “Industrial
Process” application, page 4).

GettingTheMostFromYourFan
The Fan Rating
A fan’s “point of rating” is the intersection
of the independent system resistance curve
and the fan’s characteristic performance curve
(refer to page 3 for a typical performance/system curve).
DISCHARGE
CONE
INLET
DUCTWORK
OUTLET
DUCTWORK
The resistance of the system is determined from
the airflow requirements and the ductwork elements
through which this airflow must pass. This ductwork
creates resistance to flow and is measured in terms
of pressure.
The total resistance for a system is the sum of the
total pressure resistances at the specified flow rate
(CFM) for each of the elements found in the system.
This value is the “total pressure” for which a fan is
selected.
Use of an Outlet Cone
As displayed above, fan outlet cones can be utilized
to transition an axial fan to ductwork with a diameter
larger than that of the fan. A cone of this type allows for the same quantity of air (CFM) to efficiently
reduce the velocity of the airstream at the fan outlet
to that of the cone outlet, thus converting or regaining much of the velocity pressure to static pressure.
This velocity pressure is said to be “static pressure
regained.” The advantage of using an outlet cone is
that a system that requires 1.5" of static pressure to
overcome the duct friction losses may be able to use
a fan supplying 1.25" static pressure at the fan outlet
with the additional 0.25" being produced by the static
pressure regain.
The Total Pressure Concept
Fans are utilized to develop the total pressure to
produce the specified flow rate within a system. Total
pressure can be separated into the components of
“static pressure” (analogous to the potential energy of
the airstream) and “velocity pressure” (analogous to
the kinetic energy of the airstream) at any point within
the system, where total pressure is equal to the sum
of the static pressure and velocity pressure (refer to
“Useful Formulas” on page 9).
It is common industry practice to specify a system resistance in terms of static pressure. This system static
pressure value is obtained by subtracting the velocity
pressure from the system total pressure.
When a cone is used, the static pressure regain is
defined as the increase in static pressure developed
from the conversion of velocity pressure at the fan
outlet minus the velocity pressure at the cone outlet:
SP Regain (ideal) = VP Fan – VP Cone
This velocity pressure is calculated based on the velocity of the specified airflow at the designated crosssectional area.
Although several quick rules of thumb are available to
estimate this amount, upon final selection the actual
SP regain for the specific fan size must be calculated
and deducted from the rated static pressure.
TCVX AXIFAN® ratings are established from tests with
the data corrected to the cross-sectional area of the
fan outlet. It is important to note that to maintain accuracy, the specified system static pressure should be
calculated at the same cross-sectional area as that of
the fan outlet.
The same principles can be used to adapt a fan outlet
to any cone diameter larger or smaller. Given the
same principles, additional velocity pressure can be
imparted to a system by coning to a smaller diameter.
If the system does not have a cross-sectional area
the same as the fan outlet, the true static pressure
capability of the fan will be greater or less than the
cataloged rating. This is due to the portion of the
velocity pressure being converted to (or from) static
pressure, with the total pressure remaining constant.
Please note that this simplified explanation does not
take into account any inherent ductwork or energy
conversion losses. It should be further noted that static pressure regain calculations are approximate and
are not a part of the AMCA certified ratings program.
The cone dimensions shown below are for Twin City
Fan & Blower standard cones which are the equivalent of the next fan size larger with an angle of divergence of 10. To aid in the calculation of SP regain,
this chart displays inside dimensions and outlet area
for TCVX AXIFAN® units and the Twin City Fan &
Blower standard cone.
Due to industry preferences, TCVX AXIFAN® ratings
are displayed in this catalog in static pressure (at
the fan outlet area) only. In order to properly rate
axial flow fans on a static pressure basis, the system
cross-sectional area must be considered and the total
pressure concept should be used.

Sample Selections
The following examples illustrate conditions that may
be encountered with the TCVX AXIFAN®. For additional performance corrections refer to the Twin City
Fan & Blower Fan Selector Program.
Total Pressure (TP) =
Static Pressure (SP) + Velocity Pressure (VP)
Example 1: Make the optimum selection for an
Arrangement 4 TCVX AXIFAN® at 20,000 CFM and
1.5" SP at standard conditions (0.075 lb/ft3 density).
The performance tables direct us to a 36D5 fan size
operating at 1170 RPM. Interpolating within this table
yields the following selection:

Where total (or mechanical) efficiency is calculated

Performance Tables
The performance tables in this catalog are based on
standard air density which is defined by AMCA as
that of dry air at 70°F and sea level pressure (29.92
inches of mercury). This is equal to a density value
of 0.075 lb/ft3.
When a fan operates at other than standard conditions, the values must be converted to equivalent
standard values before the fan can be selected from
the performance tables, and then reconverted back
Example 2: Make the optimum selection for an Arr. 4
TCVX AXIFAN® at 20,000 CFM and 1.5" SP at 150°F
and 10,000 feet elevation. Using the temperature and
altitude density ratios from the table below, find a
factor of 0.598. Dividing the operating SP by this
factor (1.5 ÷ 0.598) = 2.5" equivalent SP at standard
air and density. The performance tables direct us to
the 32D6 fan size at 1750 RPM. Interpolating within
this table yields a BHP of 13.77 and an approximate
blade angle of 37°.
This is the BHP required at standard air density (0.075
lb/ft3), often referred to as “cold or starting horsepower.” However, the actual BHP at the operating
conditions of 150°F and 10,000 feet elevation will be
13.77 x 0.598 = 8.22. The selection is:
32D6 TCVX @ 1750 RPM @ 8.22 BHP @ 37° blade
angle
Example 3: If the operating density is known, this
same air density ratio can be calculated by:
Operating Density ÷ 0.075 = Factor
The factor is then used as in Example 2.

TypicalSpecifications
Fans shall be Model TCVX AXIFAN® Adjustable Blade Vaneaxial fans, as manufactured by Twin City Fan & Blower,
Minneapolis, Minnesota. Fans shall be Arrangement 9, V-belt driven with the fan wheel mounted on a separate
shaft and bearings supported completely within an enclosed tube isolated from the high velocity airstream or
Arrangement 4, having the fan wheel mounted directly on the motor shaft with the wheel and motor assembly
enclosed entirely within the fan housing. The blade pitch angle of attack shall be individually manually adjustable
when the fan is stopped.
PERFORMANCE — Performance ratings shall conform to AMCA Standard 205 (fan efficiency grade), 211 (air
performance) and 311 (sound performance). Fans shall be tested in accordance with ANSI/AMCA Standard 210
(air performance) and 300 (sound performance) in an AMCA accredited laboratory. Fans shall be licensed to bear
the AMCA certified ratings seal for both sound and air, and fan efficiency grade (FEG).
Model TCVX shall be available UL 705 listed. Fans shall bear a permanently attached nameplate displaying model
and serial number of the unit for future identification.
CONSTRUCTION — Fan housings shall be of welded one-piece 12-gauge ASTM A-569 hot rolled steel on sizes
18 and 21, 10-gauge hot rolled steel on sizes 24 through 36, 7-gauge hot rolled steel on sizes 42 through 60,
and 1∕4 inch hot rolled steel on sizes 66 through 84. The housing seam shall be continuously welded and ground
smooth for less resistance to airflow. Inlet and outlet flanges are standard.
GUIDE VANES — Fan housings shall be fitted with eleven aerodynamically designed, stationary, straightening
guide vanes on the air discharge side of the fan wheel. Vanes shall be welded to both the housing and the inner cylinder and act to straighten the swirling motion of the air downstream of the fan blades, thereby recovering
rotational energy losses, improving efficiency and static pressure capability, reducing power requirements, and
reducing fan noise generation.
WHEEL — The fan wheel shall be of individually manually adjustable blade pitch design and shall consist of a
hub and blade assembly of permanent mold A356-T6 heat treated aluminum alloy castings. The wheel shall have
blades of airfoil shape designed with a variable hub ratio system to allow the selected fan to operate at the highest efficiency possible. The blade pitch angle shall be completely adjustable through a service access door located
in the fan housing. It shall never be necessary to remove the fan from the system or remove any connecting
ductwork to manually adjust the blade pitch settings. Blade angle markings shall be permanently stamped into
each blade and a corresponding index mark shall be permanently stamped into the hub near the blade sockets.
The fan wheel assembly shall be machined to the proper diameter so that blade tip clearance shall be within tolerance necessary to insure certified fan performance. The fan wheel shall be secured to the fan/motor shaft with
a Trantorque® or taperlock bushing. The blade angle is to be factory set at the blade angle required to achieve
the specified flow rate and pressure. This blade angle shall be indicated on the fan nameplate.
SHAFT (ARR. 9) — Shafts shall be AISI 1040 or 1045 hot rolled steel, accurately turned, ground, polished, and ring
gauged for accuracy. Shafts shall be sized for the first critical speed of at least 1.43 times the maximum speed.
BEARINGS (ARR. 9) — Bearings shall be heavy duty, grease lubricated, anti-friction ball or roller, self-aligning,
pillow block type and selected for a minimum average bearing life (AFBMA L-50) in excess of 200,000 hours at
the maximum fan RPM. All bearings shall be provided with pre-filled factory extended lubrication lines fitted with
grease fittings terminating at the housing exterior.
DRIVE (ARR. 9) — Fans shall be equipped with a (fixed/adjustable) pitch V-belt drive selected to operate at the
required RPM. The V-belt drive is to consist of cast iron sheaves and anti-static conducting belts. Drives shall be
selected with a (1.2/1.5) service factor based upon the required brake horsepower of the fan.
The complete fan shaft and bearing assembly is mounted within a steel fabricated inner cylinder. The V-belt drive
assembly is extended through a two-piece belt fairing which is continuously welded to both the housing and inner cylinder, thus avoiding any direct contact between the belts and high velocity airstream. The belt fairing is to
be an aerodynamically shaped tube designed to maximize fan efficiency, minimize air blockage and reduce noise
generation.
