General Layout Guidelines
How to Layout an Alliance Air Custom Air Handler
A. Size the Fan
Step 1. Select a fan that meets your operating criteria (CFM, TSP, maximum HP, sound attenuation requirements, etc.) using the ACES fan program.
Step 2. Find the minimum section dimensions for the selected fan using the Minimum Section Dimension tables from pages 8 through 12.
B. Size the Cabinet
Step 1. Using the Overall Unit Cabinet table from page 13, select a cabinet size (internal cabinet height and internal cabinet width) that:
• Fits the selected fan.
• Meets the required CFM with a maximum 500 fpm coil or filter face velocity.
• Fits the site dimensions.
• Meets the shipping requirements.
Step 2. Using the Section Dimension tables from pages 13 through 26, select all applicable components for the selected cabinet:
• Coil (max 500 FPM) using table from page 15.
• Filter (max 500 FPM) using tables from pages 16 through 18.
• Mixing box or economizer (1,200 to 1,500 damper velocity) using tables from pages 19 through 25.
• Direct evaporative cooler (max 500 FPM) using table from page 26.
C. For special requirements, please contact factory.

General ConstructionWalls :: Roof :: Base :: Insulation
Unit BaseBase perimeter is structural "C" channel with
2" x 4" tubular structural steel cross members
on maximum 24" centers. Galvanized steel
stringers are placed in the direction of airflow
on maximum 24" centers for additional floor
support. All fans and coils are supported by
welded structural steel cross members. The
structural C channel is sand blasted before
assembly to remove all rust and mill scale. All
base members are fully welded. The floor is
constructed from 16 gauge bright galvanized
steel using standing seams capped with cleats.
All floor seams have structural members
centered underneath for support. Floor panels
are welded from below to supporting members.
There are no penetrations through the floor
material. Urethane foam insulation is applied
under the base and lined with 20 gauge bright
galvanized steel.
Roof PanelsRoof panels are constructed from the same
material as the wall panels. Roof panels utilize
standing seam construction with cleats over
the roof flanges that provide a weatherproof
design. Outdoor units have a minimum of 1/4
inch per foot slope to ensure rain and snow
runoff.
Wall Panels
Standard wall construction consists of 16
gauge paint grip galvanized steel panels.
Panels are attached to the floor, roof and each
other with 1/4" bolts and are caulked and
sealed during assembly to produce an airtight
seal. The panels are designed to operate at a
static pressure of positive or negative 8 inches
pressure differential while maintaining a
leakage rate below 1% of design air volume.
Standard panels are 2" thick. Other gauges
and materials are optional.

InsulationWalls and roof are insulated with 2" thick
1.5 lb/ft insulation. Other thicknesses and
densities are optional. Surfaces exposed to
airflow are protected with an acrylic coating on
the insulation to prevent fiber erosion.
Insulation provided meets NFPA 90A
requirements. The unit base is insulated with
2" minimum of sprayed urethane foam. In
addition to providing a more rigid walking
surface, urethane foam provides an R-Value of
at least 11.5.

Plenum Fan
Plenum fans are AMCA certified for sound and air performance. Standard fans are Arrangement 3 or Arrangement 1. Also available are direct-drive, Arrangement 4.
Standard fan wheels are high efficiency, airfoil design. Twelve blade wheels are available for improved sound performance. Fan blades are continuously welded to the fan backplate and spun inlet shroud. Wheels are statically and dynamically balanced in accordance with ANSI/AMCA 204-96 to Balance Quality Grade G6.3.
The frame and inlet panel are constructed of heavy gauge steel continuously welded at all connections for maximum strength and rigidity. Inlet cones are spun from heavy gauge steel. The cone is closely matched to insure quiet, efficient operation.
For Arrangements 1 and 3, bearings are ball or spherical roller, heavy duty, self-aligning, pillow block type. Bearings are mounted to structural steel supports and selected based on an average life of 200,000 hours. Shafts are AISI 1040 or 1045 hot rolled steel accurately turned, ground, polished and ring gauged for accuracy.
Sheaves are cast iron, variable pitch on applications with 5 HP and smaller, fixed pitch for 7.5 HP and larger. Drive and belts are rated for 150% of the required motor HP.
Fan and motor assemblies are mounted to a heavy welded structural base and supported at four points on rubber mounted 2" deflection isolator springs. All fan supports are designed for Zone 4 seismic restraint.
Prior to unit shipment, the complete fan assembly; including motor, drives and spring isolation assemblies, is factory balanced in accordance with ANSI/AMCA 204-96 to Balance Quality Grade G6.3.
Piezometer Ring (Airflow Measurement System)
A piezometer ring is available on plenum fans, as well as housed fans, as part of an airflow measurement system based on the principles of a flow nozzle. The inlet cone of the fan is used as the flow nozzle. The flow can be calculated by measuring the pressure drop through the inlet cone. No tubes or sensors are inserted in the high velocity airstream which could obstruct airflow.
The system consists of a piezometer ring mounted at the throat and a static pressure tap mounted on the face of the inlet cone. A differential pressure transducer and digital display can also be provided.
The pressure drop is measured from the tap located on the face of the inlet cone to the piezometer ring in the throat. The inlet tap is connected to the high-pressure side of the transducer and the piezometer ring is connected to the low-pressure side. See the diagram on the right.
Based on laboratory tests, the system was determined to be accurate within ±5%.

Fundamentals of Acoustics
1. Sound Power and Sound Pressure
Sound power and sound pressure are two fundamental units for the measurement of sound transmission.
Although both sound power (SWL) and sound pressure (SPL) are measured in decibels (dB), they are derived
from different units. Sound pressure is the ratio between the measured pressure level in Pascals and a reference
level expressed as:
SPL = 20log(ref
meas
P
P )
where Pref = 20 µPa. Sound power is the ratio between the measured power level in watts and a reference level expressed as:
SWL = 20log(ref
meas
W
W )
where Wref = 10-12
watts (1 picowatt). It is important to understand the difference between these two units; sound
pressure decreases with increased distance from the sound source, and in this way is similar to light emitted from
a light bulb – the farther you are from the light source, the dimmer the light appears. This happens because the
light radiates in all directions from the source in a spherical pattern. The farther from the source, the greater the
area of the sphere, and the less light is available at any point on the sphere. The same is true of sound pressure
– the farther it travels, the more it decreases, and this is why sound pressure levels should always be referenced
to the distance from the sound source.
Sound power is an absolute measure of sound energy, and is independent of distance. In this way, sound power
is similar to the power output of a light bulb, and is in fact expressed in the same basic units – Watts. A 50 watt
light bulb is a 50 watt light bulb no matter how far away it is, and the same is true of sound power – it is a
measure of the intensity of the sound source and therefore is a reliable way to compare sound sources
independent of other variables.
2. Octave Bands and Multiple Noise Sources
The audible frequency spectrum is normally divided into eight octave bands. These bands cover audible
frequencies from 45 Hz to 11,200 Hz. Each octave band is identified by its center frequency, as shown in Table 1:
When there is more than one noise source, for instance two or more fans in parallel, the sources must be added
logarithmically to arrive at a single sound power spectrum. Two noise sources expressed in dB, S1 and S2, can
be added logarithmically using the following equation:
