Severe Duty Options
High Wind and Hurricane
Greenheck is leading the high wind standard for roof top fans and ventilators. Forceful winds and windborne debris are
the cause of most hurricane damage. Hurricane winds start at 75 mph. At speeds over 150 mph, wind can exert a force of 75 pounds per square foot of pressure or over 900 pounds on a fan. Forceful winds are not the only problem, wind-borne debris can also cause detrimental effects to objects and structures. High winds and extreme forces are the cause of most storm damage. By analyzing calculations, computer simulations and actual testing—Greenheck developed the High Wind Standard.
Protocols designed to protect against wind borne debris and severe wind loads:
Greenheck worked with Miami-Dade County to outline a high velocity hurricane zone standard for rooftop fans. The SFD, SFB and SWB Series 100 and 200 have
Miami-Dade been certified by an independent third County Test party to the ASTM E-330 Static Pressure
Protocols Difference Standard, Florida Building Code Test Protocol TAS-201 (large missile
impact), 202 (static pressure difference) and 203 (cyclic pressure) Static Pressure Difference. NOA #09-0303.31

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 fan 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
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.

UL/cUL 762 - SWB Series 200 and 300 models are listed for grease removal (UL/cUL 762). The UL/cUL 762 option includes a weatherhood, threaded drain connection and access door. Indoor mounting requires the fan to have welded scroll construction.
Weatherhood - Available to completely cover the motor and drive compartments; protecting the shaft, bearings, motor and drive components from moisture and other adverse weather conditions. Weatherhoods are vented to provide sufficient motor cooling, designed to meet OSHA guidelines and are easily removed for service access. Series 300 includes an access door.
Drain Connection - Threaded drain connections can be provided to drain moisture from the bottom of the fan housing.
Grease Trap (SWB Only) - Aluminum trap is designed to collect grease residue and avoid drainage onto roof surface. Disposable grease absorbents are available for easy maintenance.
Access Doors - Access doors provide access for inspection and cleaning. Either bolted or hinged, quick opening access doors are available on all models except SFD. (Series 100—bolted option only)
Welded Scroll Construction - Welded scroll construction is available on SWB Series 200 and 300.
Aluminum Construction - Aluminum airstream option is available on SWB Series 200.
Dampers - Gravity or motorized parallel blade backdraft dampers feature sturdy galvanized frames with prepunched mounting holes, aluminum blades with felt edges and balanced design for minimal resistance to airflow. Backdraft dampers are not suitable for downblast or bottom
angular downblast discharge positions. The fan must be supplied with a flanged outlet to install a backdraft damper directly to the fan. Heavy-duty dampers are available for high pressure applications on fans with motors equal to or greater than 71⁄2 horsepower.
Disconnect Switches - A wide selection of NEMA rated switches are available
for positive electrical shutoff and safety, including: dust-tight, rainproof and corrosion-resistant.
Wiring Pigtail - Allows direct hookup to the power supply eliminating field wiring to the fan.
Extended Lube Lines - Lubrication lines with grease fittings are extended from shaft bearings to the base of the drive frame panel or weatherhood for easy bearing lubrication.
8
Inlet and Outlet Guards - Constructed of expanded metal mounted in a steel frame to provide protection for non-ducted installations. The guards can be easily
removed for fan maintenance or inspection.
Flanged Inlet and Outlet - Flanges are available for damper mounting or flanged duct connections. Inlet flanges have prepunched mounting holes. Outlet flanges are bolted on standard; welded for UL 762 applications
Companion Flange - Connects to the inlet flange and then attaches to the ductwork. Recommended for slip-fit duct connections.
Inlet Vane Dampers (SWB only) - External inlet vane dampers are available on model SWB fans, sizes 112– 124 and 212–224. External vanes are mounted on the inlet flange. Inlet vane dampers feature
zinc-plated steel blade axles, stainless steel washers and bearings. Vanes can be used for either manual or automatic operation, with controls furnished
by others. Maximum operating temperature is 200°F (93°C).
Coatings - A wide variety of coatings and
colors are available for decorative to acidic applications on SFB and SWB Series 200 and 300. All Greenheck coatings can be found in the Performance Coatings for Commercial and Industrial Fans publication.
Permatector™ is our standard coating. Typically used for applications that require corrosion resistance in indoor and outdoor environments.
Hi-Pro™ Polyester is resistant to salt water, chemical fumes and moisture in more corrosive atmospheres. Typically used for applications requiring superior chemical resistance, excellent abrasion and outdoor UV protection. This coating exceeds protective qualities of Air Dried Heresite and Air Dry Phenolic.
Baked Enamel Decorative Coatings are heat cured enamels applied as electrostatic powders. Customers can choose from 16 standard decorative colors or color match any color.
Heat Slinger and Shaft Seal (all belt models) - Heat slinger is an aluminum cooling disc mounted on
the fan shaft between the inboard bearing and the fan housing. The disc dissipates heat conducted along the fan shaft.
The shaft seal with an aluminum rub ring is available for applications where
contaminated or high temperature air is being handled.
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 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 to indicate load capacity.
Rubber Mounts -
Type 2, ¼-inch and
½-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. If there is
any doubt whether or not equipment can be
supported directly on isolators,
use rails, bases or consult the factory.
Equipment Supports
Models GESS and GESR equipment supports are available for roof mounting of utility fans up to size 36. Equipment supports are available in a number of lengths, widths, heights,
and can also be built for a pitched roof.
Mounting Rails with Isolators
Isolation mounting rails are available with 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. Mounting rails are available for fans up to size 36.

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 wheels are available:
1.Backward-inclined or airfoil wheels turn at twice the speed of forwardcurved fans and feature:
•Higher operating efficiencies
•A non-overloading horsepower curve which reaches a peak near the middle of the normal operation range
•Stronger wheel design allowing for operation at higher static pressures
2.Forward-curved wheels typically have lower performance capabilities compared to the backward inclined and contain:
•Overloading type wheel (meaning that changes in performance can result in significant brake horsepower changes)
•Forward-curved wheels have lower sound levels
Comprehensive air performance data for these utility fans can be found in the fan tables and fan curves section, starting on page 15.

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