Motor Starting Torque
Moments of Inertia (lb-ft2)
When selecting a motor for a centrifugal 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.
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.

Effect of Air Density — High Suction at Fan Inlet
The density used for fan selection is that which is measured at
the fan inlet. When the inlet total pressure exceeds 10 inches in
suction, the density at the fan inlet should be corrected by the
following values. These values should be multiplied to the fan static
pressure and the result used for the proper fan selection. With
suction pressures less than 10 inches, this correction is typically
ignored.

Maximum RPM Correction Factors For High Temperatures
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.

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
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.

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 BISW
centrifugal fan is to deliver
16,500 CFM at 8.1 inches wg
static pressure. Elevation
is 2000 feet, temperature is
150°F.
The 8.1 inches wg static
pressure refers to the static
pressure at the operating air
density, in this case at 2000
feet, 150°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 8.1 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.

performance at sea level and
at 2000 ft. elevation and 150°F.
Example:
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 16,500 CFM.
2. Determine correction factor from chart for an elevation of 2000 feet and air temperature of 150°F. The correction factor is 0.808.
6. Since the horsepower selected refers to standard air
density, this must be corrected to reflect actual BHP at
the lighter operating air.
Operating BHP = Standard BHP x 0.808, or 35.7 x 0.808
= 28.8 BHP.

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 BISW

Sound Performance Testing
AMCA Licensed Ratings
Sound tests of Model BISW and AFSW 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 single-width
centrifugal fans. Typically, fan manufacturers publish only inlet sound for single-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.

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 calls 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.
% WOV =
CFM x 100
RPM x K
Use the following procedure to calculate sound data for a specific Fan RPM and % WOV:
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 19,100 CFM at 4.0 Ps.
This gives us a fan RPM of 995, requiring 17.2 BHP,
with Class I construction.
EXAMPLE
For this example, the fan operating point is at 60%
WOV using a 20 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 tables found on pages 5 and 6.
NOTE: This motor size can be compared to the
Maximum Open Frame Size chart (E) found above the
performance table.

The eight octave ratings can then
be found using the interpolation
instructions found in the Sound
Performance section on pages 8 and
9.
