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.

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.

SWB, Commercial Kitchen (Grease)

Greenheck’s SWB Series 200 and 300 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.

Diameters

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

Fans selected for grease removal must include a weatherhood, 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.

SWB Series 200 and 300 models are listed for grease removal (UL/cUL 762).
