Spark-Resistant Construction Options

The following AMCA Standards apply to fan
applications that may involve the handling of
potentially explosive or flammable particles, fumes
or vapors.

•AMCA Type A - All parts in contact with the

airstream are constructed of nonferrous material
(aluminum). Model SWB does not meet AMCA
Type A Spark Resistant Construction because the
shaft is steel.

•AMCA Type B - The fan wheel is constructed

of nonferrous material (aluminum). A nonferrous
(aluminum) rub ring surrounds the fan shaft where

6

6

it passes through the fan housing. Available on all

SWB sizes with an aluminum wheel and rub ring.

•AMCA Type C - The inlet cone is constructed

of nonferrous material (aluminum). A nonferrous
(aluminum) rub ring surrounds the fan shaft where
it passes through the fan housing.

The constructions listed minimize the potential
of ferrous components making contact with each
other that may produce sparks. However, they do
not guarantee against the potential of producing
sparks. The installer must electrically ground all fan
and system components.

Mounting Options

Vibration Isolators

Base-mounted neoprene or spring isolators are available to lessen mechanical vibration and assure quiet
operation. Free-standing, restrained and housed spring isolators are also available. Isolators are sized to
match the weight of each fan.

Free-Standing Open
Spring Mounts -

Type 3, 1-inch Deflection

Free-standing spring
isolators are unhoused
laterally stable steel springs.
They provide a minimum

horizontal stiffness of 0.8
times the rated vertical stiffness and provide an
additional 50% overload capacity. These isolators
are equipped with a top-mounted adjusting bolt
and an acoustical non-skid base. Springs are color
coded or identified to indicate load capacity.

Housed Spring Mounts

Type 4B, 1-inch Deflection

Housed spring isolators
consist of steel springs
assembled into a telescoping
housing with a top-mounted
adjusting bolt and an
acoustical non-skid base.

Housed spring isolators
include resilient inserts to prevent metal-to-metal
contact and provide snubbing for side loads.
Springs provide an additional 50% overload
capacity and are color coded or identified
to indicate load capacity.

Rubber Mounts -

Type 2, 1⁄4-inch and

1

⁄2-inch Deflection

Neoprene mountings
consist of a steel top plate
and base plate completely
embedded in colored (oil­resistant) neoprene for easy

identification of capacity. Neoprene mountings are
furnished with a tapped hole in the center. This
enables the equipment to be bolted securely to the
rubber mount.

Restrained Spring
Mounts -

Type 4A, 1-inch Deflection

Restrained spring isolators
consist of laterally stable,
free-standing springs
assembled into a steel
housing. These assemblies

are designed for vertical and horizontal motion
restraint. Restrained spring isolators can be used
for blocking during equipment installation and are
provided with leveling bolts. Springs provide 50%
overload capacity and are color coded or identified
to indicate load capacity. Restrained spring mounts
are recommended for equipment subject to wind
loading or large torquing forces.

Direct Mount - Type A

No base required. Isolators
are attached directly to
equipment. Direct isolation
can be used if equipment
is unitary and rigid without
the use of additional
support. Direct isolation
is not recommended for
equipment having large
overhung loads (e.g. motors on
Arr. 9 fans). If there is any doubt
whether or not equipment can be
supported directly on isolators, use
rails, bases or consult the factory.

Mounting Rails
with Isolators

Isolation mounting rails are
available with ¼-inch of
deflection and either rubber
mount, free-standing open
or restrained spring isolators.
The isolators are mounted
between aluminum rails
that run the length of the fan
base. Isolation rails provide easy
installation on isolated systems,
and are ideal for applications where
there is a large overhung load.

Equipment Supports

Models GESS and GESR equipment supports are available for roof
mounting of all utility fans. Equipment supports are available in a number
of lengths, widths, heights, and can also be built for a pitched roof.

Engineering Data

Selection

The first consideration in any fan
selection is the amount of air to be
moved and the resistance to this air
movement. Air volume requirements are
established through specific codes or
accepted industry standards. Once the
air volume is known, system resistance
can be determined by summing up the
losses through the system components.
Duct layout, duct size, coils, filters,
dampers, and fan accessories all affect
system resistance. ASHRAE Guide and
Data Books and manufacturer’s data
on individual system components are
common sources of information available
to the system designer.

In most applications, several fans may
meet the required airflow and system
resistance conditions. An optimum
fan selection requires evaluation of
alternative fan types and fan sizes, as
they relate to initial cost, operating cost,
available space, and allowable sound
levels. The relative importance of these
facts varies with each system.

TWO TYPES OF FANS ARE AVAILABLE:

Effects of Installation on Performance

Fan ratings presented in the performance tables and curves
of this catalog are in accordance with AMCA Standard 210
“Laboratory Methods of Testing Fans for Aerodynamic
Performance Rating.” The AMCA test procedure utilizes an
open inlet and a straight outlet duct to assure maximum static
regain.

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 prerotation 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.

The examples below show system layouts and inlet and
discharge configurations which can affect fan performance.

SWB Typical Installations

3 Wheel

Diameters

SFD, SFB and SWB

General Clean Air or Fume Hood (Non–Grease)

The SFD, SFB and
SWB are designed for
applications ranging from
clean air to contaminated
air. Typical installations are
shown below. Installations
must include a means for

Flex

inspecting, cleaning and
servicing the exhaust fan.

SWB

Model SWB Series 100 and 200 are designed for supply, exhaust and return air applications. Tests
were conducted to assure safe, rugged and reliable fans capable of withstanding severe conditions.

Due to the varying airstreams encountered in commercial ventilation, system designers must be
aware of national, state and local codes and guidelines governing these installations.

SWB, Commercial Kitchen (Grease)

Greenheck’s SWB Series 200 are designed to meet restaurant and foodservice applications. These fans
are UL and cUL Listed for grease removal and have been tested under elevated temperature conditions.

Due to high temperatures and grease-laden airstreams in commercial kitchen ventilation, system designers
must be aware of governing codes and guidelines. The National Fire Protection Association (NFPA) is
the primary source used by many local codes for commercial kitchen ventilation systems. Local code
authorities should be consulted before proceeding with any kitchen ventilation project.

Installation must include a means for inspecting, cleaning and servicing the exhaust fan.

Fans selected for grease removal must include a weatherhood, bolted access door and 1-inch (25 mm)
drain connection. For grease applications where the fan is mounted indoors, the welded scroll option
must be selected. An outlet guard is strongly recommended when the fan discharge is accessible. When
an outlet guard is not ordered with the fan, it must be provided by the installer. An upblast discharge is
recommended. No dampers are to be used in the system.

The fan discharge must be a minimum of 40 inches (1016 mm) above the roof line and the exhaust
duct must be fully welded to a minimum distance of 18 inches (457 mm) above the roof surface.
