Motor Starting Torque
Moments of Inertia (lb-ft2)
When selecting a motor for an industrial process fan, the motor
must be capable of driving the fan at operating speed and also
capable of accelerating the fan wheel, shaft and drive to the
operating speed.
Moments of inertia are shown for steel wheels. Aluminum wheels
are one-third of the value shown.
For a belt drive industrial process fan, the required motor starting
torque capability can be expressed by the following formula:

The fan performance tables and curves in this catalog show the
brake horsepower required to operate the fan once it is brought to
operating speed. For applications requiring a large air volume at a
low static pressure, the BHP required at the fan’s operating RPM
may not be sufficient to initially start the fan. If the time required to
bring the fan to speed is excessive, the motor winding insulation
can be damaged due to excessive temperature rise and the life of
the motor seriously affected.

V-Belt Drives
Constant Speed Drives
Advantages of constant speed drives include low vibration levels,
ease of assembly and low cost. Fan speed changes can be
accomplished in most cases simply by changing the motor pulley.
Fan RPM Limitations
The maximum allowable wheel RPM shown on the fan performance
pages are for fans of standard steel operating at 70°F. Since the
strength of the fan wheel, shaft and bearings decreases with an
increase in temperature, maximum allowable speeds must be
reduced by the correction factors shown below.
Constant speed drives are recommended over variable speed
drives for applications that require motors 15 HP and larger, and all
applications requiring 3600 RPM motors.
Variable Speed Drives
Variable speed drives allow the fan speed to be changed by
adjusting the pitch diameter of the motor pulley. The power to the
fan must be off and locked out, and the belts must be removed
before manually adjusting the variable pitch pulley.

Inlet Vane Performance
As inlet vanes are closed, they impart a spin to the airflow in the direction of wheel rotation and reduce airflow, static pressure and brake
horsepower as shown in the graphs below. The graphs show how CFM, static pressure and brake horsepower are affected as inlet vanes
are modulated from 100% open to 0% open in a typical variable air volume system. Graph 3 provides RPM and BHP correction factors for
fans equipped with inlet vanes.

Engineering Data
Effect of Air Density – Temperature and Elevation
Ratings in the fan performance tables and curves of this catalog are based on standard air (clean, dry air with a density of 0.075 pounds per
cubic foot, barometric pressure at sea level of 406.75 inches wg, temperature of 70°F). Selecting a fan to operate at conditions other than
standard air requires an adjustment to both static pressure and brake horsepower.
One cubic foot of air has a constant volume regardless of temperature or elevation. However, air density changes with non-standard
temperature or elevation. Therefore, when selecting a fan to operate at a non-standard air density using standard air density tables and
curves, corrections must be made to parameters affected by air density. These parameters are static pressure and brake horsepower.
For example, a size 30 BIDW
centrifugal fan is to deliver
35,000 CFM at 4.5 inches
wg static pressure. Elevation
is 4000 feet, temperature is
100°F.
The 4.5 inches wg static
pressure refers to the static
pressure at the operating air
density, in this case at 4000
feet, 100°F. Intuitively, we
realize that at higher than
standard elevations and
temperatures, air density
will be lower than standard.
Therefore, we must determine
what static pressure at
standard air density will
equate to 4.5 inches wg static
pressure at our operating
density. Since standard
air density is greater than
operating air density in this
case, we would expect the
corrected static pressure to
be greater than the operating
static pressure.
Dry Air Density Correction Factor (I-P)
Multiply Standard Air Density, 0.075 lbm / ft3 by the Factor to obtain Density at Condition pb
Altitude, (Z)
Barometric Pressure
( pb )
Temperature °F, (t)
The accompanying table
gives air density correction
factors for non-standard
temperatures and elevations.
The example below shows
the relationship of fan
performance at sea level
and at 4000 ft. elevation
and 100°F.

The following example shows how to properly select the fan described above:
1. Since the air volume delivered by the fan is not affected by density, airflow remains 35,000 CFM.
2. Determine correction factor from chart for an elevation of 4000 feet and air temperature of 100°F. The correction factor is 0.817.

If a fan is selected to operate at high temperatures, the motor
must be of sufficient horsepower to handle the increased
load at any lower operating temperature where the air is more
dense. Assume the air entering the 30 BIDW fan at start-up is
0°F. For 0°F and 4000 feet elevation, the air density correction
factor is 0.995

Engineering Data
Effect of Installation on Performance
Discharge Duct Turns
Ratings presented in the performance tables and curves of this
catalog were derived from tests made in accordance with AMCA
Standard 210 — “Laboratory Methods of Testing Fans for Ratings.”
The AMCA test procedure utilizes an open inlet and a straight
outlet duct to assure maximum static regain.
Ro
t
Any installation with inlet or discharge configurations that deviate
from this standard may result in reduced fan performance.
Restricted or unstable flow at the fan inlet can cause pre-rotation
of incoming air or uneven loading of the fan wheel yielding large
system losses and increased sound levels. Free discharge or
turbulent flow in the discharge ductwork will also result in system
effect losses.

POOR
Ro
t
Static pressure losses due to inlet and discharge conditions can
be expressed in terms of system effect factors. The static pressure
for selection of the fans equals the system static pressure plus the
system effect factor.

Length of Straight Duct
Some common inlet and discharge conditions which affect fan
performance are:
Non-Ducted Inlet Clearance
GOOD
Duct turns located near the fan discharge should always be in the
direction of the fan rotation.
Fan performance is reduced when duct turns are made immediately
off the fan discharge. To achieve cataloged fan performance there
should be at least three equivalent duct diameters of straight
ductwork between the fan discharge and any duct turns. Curve #3
shows the system effect factor for two diameters of straight
ductwork and Curve #1 for one diameter.

Installation of a fan with an open inlet too close to a wall or
bulkhead will cause reduced fan performance. It is desirable to
have one fan wheel diameter between the fan inlet and the wall.

wheel diameter clearance.

Sound Performance Testing
AMCA Licensed Ratings
Sound tests of Model BIDW and AFDW were conducted in Greenheck Fan Corporation’s AMCA Accredited sound laboratory in accordance
with AMCA Standard 300. Inlet and outlet sound ratings comply with AMCA Publication 311, qualifying these models to bear the AMCA Seal
for Sound and Air Performance. The sound power levels published here can be compared directly with those of other similarly rated fans, or
used as a baseline to determine sound levels in occupied spaces.
The sound data in this brochure is the result of extensive testing, which included both inlet and outlet sound tests on double-width
centrifugal fans. Typically, fan manufacturers publish only inlet sound for double-width fans. The assumption they make is that outlet sound
is identical to inlet sound. Sound data based on this assumption is simply not accurate enough for today’s sound sensitive installations. This
assumption also ignores duct end corrections for outlet sound.
Test Methods
AMCA Standard 300 clearly defines methods used to test fans in a reverberant sound test room. The reverberant room is specifically
designed to allow sound waves to be dispersed evenly throughout the room. The walls have a hard surface that reflects sound and are
positioned to prevent resonances which could result in quiet areas within the room.
Sound power cannot be directly measured. The test method is based on a Reference Sound Source (RSS) substitution for determining fan
sound power. The RSS is a laboratory calibrated device which has a known sound power output level. The test fan is installed as shown
below. The RSS is energized and the sound pressure levels in the reverberant room are recorded. The fan is then operated without the RSS
and the fan sound pressure levels are recorded for various points of operation. Since the sound power levels of the RSS are known, the
substitution method is used to determine the sound power levels of the fan. This method is illustrated in the following example.

Test Setups
The illustrations show where the sound levels were measured with respect to the fan. Inlet sound was tested as in Figure 2 of AMCA
Standard 300 and outlet sound was tested as in Figure 3. Inlet and outlet sound were determined in the same inlet and outlet configurations
as the air tests. (Installation Type B - Free Inlet, Ducted Outlet).
Since double-width fans are more often ducted at the inlet, they are tested only for sound radiated from the fan inlet.

Interpreting Sound Data
Sound power levels in this catalog are presented as dB (re 10-12 watts) in each of the eight full octave bands with center frequencies from
63 Hz to 8000 Hz. They are also presented as a single A-weighted sound power level, LwA. Charts are provided covering the full range of
fan speeds and percent wide open volume (% WOV) for each fan size. Outlet sound power data is based on a ducted outlet and therefore
includes duct end reflection corrections.

Sound Performance Testing
Outlet Sound – Duct End Corrections
Duct End Corrections (dB)
This correction accounts for sound that is reflected back into the
duct where there is an abrupt termination of the duct.
Size
AMCA Standard 300 requires that outlet sound power for fans with
ducted outlets include Duct End Corrections. These corrections
account for any sound power that may be present in the duct but is
not measured in the reverberant room, because it is reflected back
into the duct at the discharge.

Tolerance and Application
The certification process in AMCA Standard 311 call for a precertification test to verify original test results. Check tests are also required
every three (3) years for each model licensed. Test data must agree with the published sound power within the following tolerance levels:

These tolerance levels are a good indication of the variance that could occur from one fan or test setup to another. Once installed however,
there are many other factors that can affect the sound power generated by a fan.
The lower frequencies (below 125 Hz) are greatly affected by vibration. Fan wheel balance, motor balance, drive alignment, etc., all affect
the vibration level of the fan and can increase sound power in the 1st and 2nd octaves. When ducts are not properly isolated from the fan,
these vibrations can be transmitted into the ducts, which can generate additional low frequency sound.
Sound power generated by a fan can also be influenced by system effects. System effects are pressure losses caused by inlet or outlet
restrictions, or other conditions causing non-uniform airflow at the inlet or discharge of a fan (see AMCA Publication 201). Examples include
inlet or outlet elbows too close to a fan, restricted inlets and fan accessories. While system effects can prevent fans from reaching their
designed air performance, they can also result in increased sound power levels. Typically, system effects cause pressure fluctuations
which influence the lower frequencies. Poor inlet conditions can also greatly increase sound levels at the blade pass frequency (BPF). The
blade pass frequency refers to how often a blade or wheel fin passes a stationary location of the housing and can be calculated using the
following equation:
Per AMCA: Blade Pass Frequency
BPF (Hz)
=
(
)
Fan RPM x Number of Blades 2
60
NOTE: All BISW and AFSW wheels have nine blades.
Sound is becoming increasingly critical for most fan installations. Greenheck employs extensive research and testing to provide sound data
that is as thorough and accurate as possible. However, sound pressure levels in occupied spaces are affected by the acoustical qualities
of the space, distance from source to receiver, etc. Therefore, published sound power data can be used only as a baseline for determining
the resulting sound pressure levels an occupant hears. While Greenheck provides products which meet published sound power levels,
no manufacturer can be responsible for poor installations or system designs beyond their control. For further information on installation
practices, see AMCA Publication 201, “Fans and Systems”.
Sound Power
Sound power data is charted for the full range of RPM and percent wide open volume (% WOV) for each unit size.
The % WOV is a convenient way to indicate the operating point (pressure and CFM) for a given fan RPM. To calculate the % WOV for a
given fan size, use the equation given on the performance page.
Use the following procedure to calculate sound data for a specific Fan RPM and % WOV:
CFM x 100
% WOV =
RPM x K
1. Determine the eight sound power levels for the specified % WOV using the higher Fan RPM shown.
2. Determine the eight sound power levels for the specified % WOV using the lower Fan RPM shown.
3. Interpolate between the higher and lower sound power levels using the specified RPM.

Sample Fan Selection
Sound and Air performance are identical for Greenheck
Series 21 and 41 centrifugal fans.
The following example explains the model number code for
both series of centrifugal fans.
The purpose of these two pages is to demonstrate the
manual centrifugal fan selection process. These pages also
contain helpful tips to check your fan selection, as well as a
step-by-step set of instructions on how to use this manual
to properly select a centrifugal fan.
An important point to remember when manually selecting
a centrifugal fan is that more than one fan is available to
meet the desired performance (CFM and Ps). Selection
criteria such as unit size, efficiency, speed, outlet velocity,
horsepower, or construction material may also dictate which
fan is chosen.

Fan Selection Procedure
STEP 1
Enter the performance table with the desired CFM
and Ps. Obtain the fan RPM, BHP and Class.
STEP 2
Enter the Fan Curve with the desired CFM and Ps.
Obtain the fan operating point, % WOV, Motor HP
and verify fan class by curve shading.
EXAMPLE
For this example, we will use 13,400 CFM at 2.0 Ps.
This gives us a fan RPM of 1847, requiring 10.9 BHP,
with Class I construction.
EXAMPLE
For this example, the fan operating point is at
85% WOV using a 15 HP motor.
NOTE: If your specific fan selection requires inlet
vanes or if the fan operating point is not at standard air
(70°F), refer to the inlet vane and air density correction
factor graphs and tables found on pages 5 and 6.
