Model TCVA
The heart of the TCVA AXIFAN® fan lies in its wheel.
Cast of high strength aluminum alloy, the one-piece
TCVA AXIFAN® wheel has been developed to maximize the highest efficiency possible. Attention to detail
in blade and hub design have created what is felt
to be the most efficient and reliable axial fan on the
market today. With the wide range of hub-to-tip ratios
available, there is a TCVA AXIFAN® to meet any air
movement requirements.
Hub-To-Tip Ratio
The multitude of TCVA AXIFAN® wheels evolves
from nine basic castings. Each casting is machined and cut to the proper diameter. By cutting
the same model casting to one of several different diameters, different hub-to-tip ratios are created.
Since each hub ratio has slightly different pressure/
efficiency characteristics, the freedom of having several wheels (different hub ratios) for a set diameter
provides the opportunity to maximize efficiency at the
required point of rating.
AXIFAN Cast
Aluminum Wheel
Housing
TCVA AXIFAN® housings are one-piece, heavy-gauge,
hot-rolled steel construction. Flanges on both the inlet
and outlet are integrally rolled and punched for attachment to ductwork or accessories as necessary.
The sheet seam is continuously welded and ground
smooth to assure efficient airflow through the housing.
On Arrangement 4 direct drive units neither the wheel
nor the motor protrudes beyond the housing, allowing
for an easy mount into existing ductwork.

Guide Vanes
The fan housing is fitted with aerodynamically designed stationary straightening guide vanes on the
air discharge side of the wheel. The guide vanes are
welded to both the inner cylinder and the fan housing
interior and function to aid in the elimination of swirl
and turbulence downstream of the fan thereby recovering rotational energy losses, improving efficiency
and static pressure capability, and reducing fan noise
generation.

Arrangements
Arrangement 9 Belt Driven
For applications that require the motor to be out of
the airstream or the versatility of a belt driven fan, the
Arrangement 9 TCVA AXIFAN® is the perfect choice.
Driven through either a fixed or adjustable V-belt drive
system, the exact point of rating can be achieved. Any
future change in rating can be accomplished through
a simple sheave change. Good for operation up to
200°F as standard, the Arrangement 9 TCVA AXIFAN®
can be customized to handle even the most severe of
conditions. Performance tables for belt driven TCVA
AXIFAN® units are located on pages 10 through 18.
Selection examples are found on page 8.
Shaft and Bearings/Inner Cylinder
Shafts for belt driven TCVA AXIFAN® units are ground
and polished steel construction machined to a suitable diameter to allow the rotating assembly to operate well below the first critical speed.
Bearings are flange mounted ball or roller type selected for a minimum average life of 200,000 hours.
Bearing life is determined in accordance with standards set forth by AFBMA (Anti-Friction Bearing Manufacturers Association). All bearings are provided with
extended lubrication lines terminating at the housing
exterior.
TCVA Arr. 9
The complete shaft and bearing assembly is mounted
within the inner cylinder, safely isolating these components from the high velocity airstream.
Belt Fairing
The V-belt drive assembly is extended through a twopiece belt fairing. The belt fairing is an aerodynamically designed tube, welded continuously to both the
inner cylinder (bearing housing) and the fan housing,
thus protecting the V-belts from the direct blast of
the airstream.
Motor
Motors for TCVA AXIFAN® Arrangement 9 fans are
standard foot-mounted NEMA design. All of the various enclosures (open drip-proof, totally enclosed, explosion proof, etc.) can be accommodated through
the use of an adjustable motor base. This motor
mounting platform pivots at several locations to offer
infinite adjustment for belt tension.
Arrangement 4 Direct Drive
Where space constraints require the use of a complete “in line” fan or the desire is for a simple,
dependable fan with minimum maintenance requirements, the direct drive Arrangement 4 TCVA AXIFAN®
is the logical choice. Constructed with the fan wheel
mounted directly on the motor shaft, this fan provides
premium efficiency with minimal obstructions in the
airstream. Performance tables for direct drive TCVA
AXIFAN® units are located on pages 19 and 20.
TCVA Arr. 4
Motor
Motors for TCVA AXIFAN® direct drive fans are footmounted, NEMA standard, totally enclosed fan cooled
(TEFC), continuous duty, ball bearing type with Class
“F” insulation and of cast iron construction when
commercially available. Motors which are equipped
with grease lubricated bearings have extended lube
lines to the housing exterior. For ease of wiring the
motor, wiring connections are extended to an external
conduit box mounted on the fan exterior. The fan
housing exterior has a duplicate motor nameplate
mounted adjacent to the fan nameplate.

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 torosoidal shape to provide
a smooth entrance to the fan. Inlet bells are flanged,
drilled, and bolted to the fan’s flanged inlet.
Inlet/Outlet Cones
Transition pieces, called cones, can be provided for
both the inlet and outlet. Cones are flanged on both
ends and drilled to match the fan’s flange. Cones are
available with an access door if required.
Inlet Bell
Inlet/Outlet Cones
Outlet cones can be utilized to provide static pressure regain, transforming velocity pressure losses into
static pressure. A greater discussion of this is provided on page 7.
Companion Flanges
For ease of installation to 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
For frequent or continuous volume control, variable
inlet vanes 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 operator mechanism is outside of the
airstream and is controlled by a single lever.
Companion Flanges
Variable Inlet Vanes
Vertical Flow
Sound Attenuation
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
Horizontal Flow
Sound Attenuation
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.
Support Legs
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 four-point support.
Suspension Clips
For horizontal flow with ceiling mounting, clips of
formed angle are welded to the fan housing for suspension via tie rods to the ceiling support structure.
Vibration Isolation

Vibration Isolation
All TCVA AXIFAN® fans can be provided with spring
or rubber-in-shear isolators as an option. Spring isolators are standard 1-inch in deflection and can be
provided for floor mount or ceiling (hung) orientation.
It should be noted that use of a loosely fitting flex
connector on the fan inlet must be avoided as inlet
obstructions and loss of rating may occur.

Accessories
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.
Weather Cover
For outdoor installations with 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 to the
fan inlet, fan outlet, cone or bell.

Shaft Seal
To limit the air entering the inner cylinder and avoid
contact of airstream contaminants with the bearing 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. Please note that a shaft seal does not make the
inner cylinder gas-tight.
Housing Door
General Observation — For inspection and maintenance
of the internal section (V-belt drive area) of TCVA AXIFAN® units a general observation access door can be
provided. Doors are 5" x 5" for fans sizes 12" to 18"
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).
Wheel Area — Similar in size and attachment to the
general observation access door, a wheel area access
door is also available. Wheel area doors differ from general observation doors in that they are double skinned
to maintain a flush surface to the housing interior, thus
eliminating the pressure losses resulting from a single
skinned door in this critical pressure developing area.
Spark-Resistant Construction
Belt driven TCVA AXIFAN® units are available with
spark-resistant construction. Various grades of spark resistance are as dictated by AMCA, Types A, B, and C.
Discharge Cap
All TCVA 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. See
minimum CFM requirements on page 9.
Curb Cap
TCVA AXIFAN® units can be supplied with a base (curb
cap), to attach to the fan flange for curb mounting. The
combination of a curb cap and discharge cap creates
an upblast style, power roof ventilator (see page 6 for
further explanation).

Designed for rugged industrial service, the TCVA
AXIFAN® is an ideal component for most industrial
air systems. The heavy duty housing construction and
large diameter shaft/bearing combinations can handle
the toughest of airstreams.
Upblast Style Power Roof Ventilator
Fitted with a discharge cap, curb cap, and a weather
cover, the TCVA AXIFAN® makes an ideal upblast
style power roof ventilator. The broad band high efficiency range makes this fan ideal for installation both
with and without ductwork attached.
Clamshell
Industrial Process
For tough industrial systems requiring frequent
cleaning and maintenance with a minimal degree of
downtime, the clamshell construction TCVA AXIFAN®
is the right fan for the job. Manufactured with two
large doors running the full length of the fan housing
and opening 180°, the clamshell fan unit provides
complete accessibility to the shaft, bearings, V-belt
drive and wheel assembly, all without removal of any
ductwork.

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 2 for a typical performance/system curve).
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
system 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.
The Total Pressure Concept
Fans are utilized to develop the total pressure required
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 formulas
on page 8).
It is a 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.
This velocity pressure is calculated based on the velocity of the specified airflow at the designated crosssectional area.
TCVA 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.
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 a portion of the velocity pressure
being converted to (or from) static pressure, with the
total pressure remaining constant.
Due to industry preferences, TCVA 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.

Ductwork
Use of an 0utlet 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.
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 cone outlet
minus the velocity pressure at the fan outlet.
SP regain (ideal) = VP fan – VP cone
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.
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 using a smaller diameter cone.
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
part of the AMCA certified ratings program.
The cone dimensions shown below are for the Twin City
Fan & Blower standard cones which are the equivalent
of the next fan size larger with an angle of divergence
of 10 degrees. To aid in the calculation of SP regain
this chart displays inside dimensions and outlet areas for
TCVA AXIFAN® units and the Twin City Fan & Blower
standard cone.

Example 2: Select an Arr. 9 TCVA AXIFAN® for 10,000
CFM @ 1.5" @ 150°F and 10,000 ft elevation. Using
the “Temperature & Altitude Density Ratio” chart on
page 9, we find a factor of 0.598. Divide the operating static pressure by this factor (1.5 ÷ 0.598) = 2.5"
SP equivalent static at standard air and density. The
performance tables direct us to the 28" fan size. Turning to page 14 for specifics we find four hub-to-tip
ratios. Comparing each we select the 28B6 as the
most efficient selection at 1542 RPM and 5.92 BHP.
This is the brake horsepower required at standard air
density (often referred to as cold, or starting horsepower). However, actual BHP at the operating conditions of 150°F and 10,000 ft altitude will be 5.92 x
0.598 = 3.54.
Selection: 28B6 @ 1542 RPM @ 3.54 BHP.
Where total (or mechanical) efficiency is calculated
using total pressure and static efficiency is calculated
using static pressure.
Example 3: If the operating density is known, this
same air density ratio can be calculated by:
Operating density ÷ 0.075 = Factor
Performance Tables
This factor is then used as in Example 2.
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 required performance is 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 to the actual conditions after the specific selection is made. The table of temperature and altitude
density ratios on page 9 should be used for this purpose with example 2 below displaying this procedure.
Sample Selections
The following examples illustrate conditions that may
be encountered with TCVA AXIFAN® units. For additional performance corrections refer to the Twin City
Fan & Blower Fan Selector Program.

Example 1: Select the most efficient Arr. 9 TCVA
AXIFAN® for 10,000 CFM @ 1.5" SP at standard conditions (0.075 lb/ft3 density). The performance tables
direct us to the 32" fan size. Turning to page 15 for
specifics on the 32" fan size we find there are four
different hub-to-tip ratios to choose from: 32B4, 32B5,
32B6, 32B7. We compare each performance of the
four hub-to-tip ratios to determine the most efficient
(lowest horsepower) selection. Consequently, our fan
selection is 32B6 @ 1047 RPM @ 3.56 BHP. The
static efficiency is 66.2%.
Example 4: Select the most economic Arr. 9 TCVA
AXIFAN® for 10,000 CFM @ 1.5" SP at standard conditions (0.075 lb/ft3 density). In evaluating first cost it
should be noted that fan versus fan, the smaller the
hub ratio the less the cost of a fan. For example, a
Model 36B4 is less expensive than a 36B5, a 36B5
is less expensive than a 36B6, and so on. With this
in mind, we start with our premium efficient selection
(32B6) and compare with the smallest hub ratio for
each diameter smaller.

Twin City Fan Catalog AX100
AC13577B
Performance — Performance ratings shall conform to AMCA Standard 205 (fan efficiency grade) and 211 (air 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 air and fan efficiency
grade (FEG).
Model TCVA shall be available UL 705 listed. Fans shall bear a permanently attached nameplate displaying model and serial
number of the unit for future identification.
HOUSING — Fan housings shall be welded of 14-gauge ASTM A-569 hot rolled steel on size 12, 12-gauge hot rolled steel
on sizes 15 through 21, 10-gauge hot rolled steel on sizes 24 through 36, and 7-gauge hot rolled steel on sizes 42 through
60. Inlet and outlet flanges are standard.
Guide Vanes — Fan housings shall be fitted with aerodynamically designed stationary straightening guide vanes on the air
discharge side of the wheel. The guide vanes shall be welded to both the inner cylinder and the fan housing interior and
function to aid in the elimination of swirl and turbulence downstream thereby recovering rotational energy losses, improving
efficiency and static pressure capability, and reducing fan noise generation.
TypicalSpecifications
Fans shall be Model TCVA AXIFAN® Vaneaxial Fans as manufactured by Twin City Fan & Blower, Minneapolis, Minnesota.
Fans shall be Arrangement 9, V-belt driven with the wheel mounted on a separate shaft and bearings supported completely
within an enclosed tube isolated from the high velocity airstream or Arrangement 4, with the propeller mounted directly on
the motor shaft and with the propeller and motor assembly enclosed entirely within the fan casing.
Wheel — The fan wheel shall be a solid one-piece sand casting of A356 - T6 Aluminum and shall contain seven blades
and an integral center hub. 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. Wheels shall be machined to the proper diameter so that
blade tip clearance shall be within tolerance necessary to insure certified fan performance. The wheel shall be secured to
the fan/motor shaft with a Trantorque® or taperlock bushing.
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 are provided with pre-filled factory extended lubrication lines terminating at the housing exterior.
Drive (Arr. 9) — The fan shall be equipped with a (fixed/adjustable) pitch V-belt drive selected to operate the fan at the
correct operational RPM. The V-belt drive shall consist of cast iron sheaves and anti-static conducting belts and shall be
selected with a (1.2/1.5) safety 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. The belt fairing shall be an aerodynamically shaped tube designed to maximize
fan efficiency. The belt fairing is welded continuously to both the inner cylinder that houses the fan shaft and bearings and
the fan housing.
Motor — Motors for Arrangement 9 fans shall be manufactured in accordance with current applicable standards of IEEE
and NEMA and, where applicable, shall meet current EPACT standards. Motors shall be foot-mounted, NEMA standard
(ODP, TEFC, Explosion-Proof), continuous duty, ball bearing type with class (B, F) insulation and of cast iron construction
when commercially available.
Motors for Arrangement 4 fans shall be foot-mounted, NEMA standard, totally enclosed fan cooled (TEFC), continuous duty,
ball bearing type with class “F” insulation and of cast iron construction when commercially available. For ease in wiring
the motor, wiring connections shall be extended to an exterior conduit box located on the exterior of the fan housing. A
duplicate motor nameplate shall be mounted on the exterior of the fan adjacent to the fan nameplate. External grease fittings with pre-filled factory extended grease leads shall be supplied for lubrication of the motor bearings on all motors that
provide grease fittings.
Finish — The entire fan assembly, excluding the shaft, shall be thoroughly degreased and deburred before application of
a rust-preventative primer. After the fan is completely assembled, a finish coat of paint shall be applied to the entire assembly. The fan shaft shall be coated with a petroleum-based rust protectant. Aluminum components shall be unpainted.
Factory Run Test — All fans with motors and drives mounted by Twin City Fan & Blower shall be completely assembled
and test run as a unit at the specified operating speed prior to shipment. Each wheel shall be statically and dynamically
balanced in accordance with ANSI/AMCA 204-96 “Balance Quality and Vibration Levels for Fans” to Fan Application Category
BV-3, Balance Quality Grade G6.3. Balance readings shall be taken by electronic type equipment in the axial, vertical, and
horizontal directions on each of the bearings. Records shall be maintained and a written copy shall be available upon request.
GUARANTEE — The manufacturer shall guarantee the workmanship and materials for its TCVA AXIFAN® vaneaxial fans at
least one (1) year from startup or eighteen (18) months from shipment, whichever occurs first.
