Model Comparison

Direct Drive Fan Selection

Two propeller and drive frame combinations are available. These models are designed and constructed for applications with static pressure ranges up to 1 in. wg. Models RE2 and RS2 are available with welded and die formed steel blades, while models RCE3 and RCS3 offer a cast aluminum propeller. For low sound applications, it is best to select the largest fan with the lowest RPM to meet the performance requirements. This ensures the tip speeds will be as low as possible.

Belt Drive Blade Designs

L Propeller: Swept, steeply pitched blade design. These propellers typically run at

lower RPMs and generate low sound levels making them the best selection for sound critical applications or applications requiring the best combination of both air and sound performance. Typically used when the static pressure is 0.5 in. wg (13 mm) or less.

H Propeller: Straight, moderately pitched blade. It is designed for applications where static

pressures are above 0.5 in. wg (13 mm). These propellers typically run at higher RPMs and generate slightly higher sound levels than the “L” propellers.

Standard Construction Features

Superior Hood Design

Greenheck’s interlocking rib design combines four material thicknesses with I-beam design principles producing a hood far superior in strength to conventional designs (an important feature in high snow or wind load regions).

Formed channels adjacent to the ribs provide water drainage to ensure weather tightness.

Hoods are available in galvanized steel, painted steel or aluminum construction. Hood support angles are heavy gauge galvanized steel.

Construction Features

• Fanhoods and bases are constructed of galvanized, aluminum, steel or painted steel as specified. Hood

panels are arched and precision roll formed for strength and weather tightness. Hoods are bolted to heavy gauge support angles. Bases include prepunched mounting holes.

• Propellers are constructed with either fabricated steel, fabricated aluminum or cast aluminum blades

and hubs. All propellers are statically and dynamically balanced. Reversing fan propellers are designed to produce a high level of efficiency over a broad selection range. Tapered airfoil blades are cast of aluminum alloy. The reversible propeller is designed to move air in both the exhaust or supply modes.

• Permanently lubricated, sealed ball bearing pillow block bearings are 100% factory tested and are

designed specifically for air handling applications with a minimum (L10) life in excess of 100,000 hours (L50 average life of 500,000 hours) at maximum cataloged operating speeds.

• Fanshafts are precisely ground and polished steel sized so the first critical speed is at least 25% over

the maximum operating speed. Close tolerances where the shaft makes contact with the bearing result in longer bearing life.

• Heavy duty ball bearing motors are carefully matched to the fan load.

• Drives shall be sized for a minimum of 150% of driven horsepower. Pulleys shall be fully machined cast

iron, keyed and securely attached to propeller and motor shafts. Motor sheaves shall be adjustable for final system balancing. Belts are static free and oil resistant.

• Driveframes (belt drive fans) or motor support frames (direct drive fans) and panel assemblies are

constructed of heavy gauge steel.

• Fanpanels are constructed of heavy gauge steel with a deep formed inlet venturi. Reversible fans are

constructed of heavy gauge steel with a double venturi for efficient airflow.

Standard Construction Features

Access and Service

Periodic maintenance requires accessibility to fan components such as motors, belts, pulleys and propellers located under the hood. Greenheck’s hooded roof propeller fan design incorporates many service friendly features which reduce maintenance time and promotes proper servicing. These features include:

• Hinged Hood - Sizes 36 and smaller are able to be hinged by removing two of the four hood fasteners.

The hood may then be laid over on the roof deck while servicing.

• Removable Hood - Sizes 36 and smaller allow for complete removal of the hood by removing the four

hood fasteners.

• Removable Birdscreens - Fan components can be quickly and easily

inspected by simply removing the quick release birdscreen sections on either end of the unit while leaving the hood in place. Birdscreens are constructed of 1/2 in. galvanized steel mesh. Filters are optional. Sizes 42 and larger should be accessed from underneath the hood by removing the birdscreen or filters.

Filtered Supply

Filtered supply fans (models RBF, RBCF, RPDRF and RPBRF) with 2-inch aluminum mesh washable filters are available for applications where contaminants must be removed from supply air. Basic hood and fan construction is similar to the non-filtered models.

Filter removal for cleaning or replacement can be easily done by opening the hood and sliding the filters out of the open end racks. In fan sizes 36 and larger, access panels on either end of the hood are provided to allow filter removal without raising the hood.

Reversible Fans

Ventilation requirements are often subject to daily or seasonal changes in temperature. Greenheck’s reversible fans (models RPDR, RPBR, RPDRF and RPBRF) are designed for non-ducted systems or those with short duct runs and offers the ability to either exhaust or supply air on demand to maintain comfortable working conditions. By exhausting excess heat or supplying fresh outside air, the reversing fan saves cooling costs. Fewer fans required on the job means lower initial costs and lower installation costs with fewer roof penetrations.

Most Units Ship Fully Assembled

To minimize installation time, most fans are shipped to the jobsite completely assembled. Due to shipping size limitations, hoods for larger fans will be shipped knocked down in sections, including any fan larger than 42. Hood assembly requires no special tools or training. Complete illustrated assembly and installation instructions are packed with each fan. See the chart to the right for models that can ship assembled.

Insect Screen Base

Tall Base

Tall bases are recommended for installations including a gravity damper or a motorized damper and greatly simplifies installation and servicing. The damper components are factory assembled as part of the tall base and shipped as a single unit reducing field assembly time and costs. Inspection, service and cleaning of the damper, actuator and linkages are made easy with an access

door including two cam latches with plated steel handles and a slide-out rack. Tall bases are designed to provide the necessary minimum spacing between the propeller and the damper. The tall base increases the standard height to provide additional weather tightness from rain and snow intake due to the elevated hood. There is ample space within the tall base for ease of initial electrical wiring.

Tie Down Feature

In locations where strong winds may occur, cable tie-downs are recommended to secure fans to roof structure to prevent damage to the hood. Cables are by others.

Four galvanized steel brackets are provided as standard on all hooded propeller roof fans as cable attachment tie-down points at the ends of each hood support rail.

Roof Curbs

Prefabricated roof curbs are available to reduce installation time and costs by ensuring compatibility between the fan, the curb and the roof opening. All curbs are available in steel or aluminum construction and are lined with fiberglass insulation to prevent condensation and reduce sound levels. See Greenheck’s roof curb catalog for complete details.

Safety Guards

Safety guards mounted to the fan inlet are recommended to protect the fan and nearby personnel in non-ducted applications. When a safety guard is not ordered with the fan, it should be provided by the installer.

Insect Screen Base

Insect screen bases are available for applications where the building must be kept free of insects, as in food processing operations. Construction is steel or aluminum with a fine mesh aluminum screen. The base includes an access door to allow the screen section to be easily removed for cleaning and periodic inspection.

Aluminum Housings

Aluminum exterior construction is available for the hood sections and bases of all models. Aluminum housings can also be coated with decorative or protective finishes.

Hood Insulation

Fiberglass insulation attached to the underside of the hood is available to minimize condensation and reduce sound (available in either 1/2 in. or 1 in. thicknesses).

Special Coatings

Special coatings are available for decorative or protective purposes. Decorative coatings are applied to exterior surfaces of the hood and base. Protective coatings are applied to the entire unit. Coatings include baked polyesters, enamels, epoxies, phenolics, vinyl and others. Protection from corrosive atmospheres requires individual consideration.

Extended Lubrication Lines

Extended lubrication lines allow for fan shaft bearing lubrication without disassembling the unit or removing the hood. Lubrication lines with grease fittings are extended from the fan shaft bearings to the exterior of the fan base.

UL/cUL 705

All belt and selected direct drive fans with totally enclosed, TE standard efficiency, single speed motors are available with the UL/cUL 705 listing for electrical.

1-Point Wiring

Available when the following items are selected: a tall base, common voltages on the motor and the actuator and disconnect mounted and wired. The wires are pulled from the motor and the actuator on the damper to the disconnect box. (Hard wiring of the components to the disconnect switch is by others.)

Exception: When a specific voltage is not available on the actuator,

Greenheck will provide a hard wired transformer to the actuator. Greenheck will then pull the wires from the transformer to the disconnect box.

Wiring Pigtail

Available only in conjunction with factory mounted disconnect switches. Liquid tight wiring extends beyond the fan and allows direct hook-up to the power supply. This eliminates field wiring within the fan. Internal or external power supply can be specified.

End Switches

Factory mounted end switches allow the damper to open completely before the fan is energized. This will reduce the back pressure and brake horsepower load on the fan motor at start-up.

Dampers

Backdraft Dampers - Exhaust and Supply - Gravity or Motorized

Backdraft dampers are constructed with a galvanized steel frame and aluminum blades with vinyl blade seals. Gravity dampers open by pressure differential and close by an adjustable spring.

Heavy Duty Backdraft Dampers - Exhaust and Supply - Motorized

Constructed with heavy galvanized steel frames and blades, these dampers are available in standard leakage, low leakage and insulated low leakage configurations. These dampers are designed to handle higher volumes of air than the standard backdraft damper. Ultra low leakage dampers with extruded aluminum blades are available with galvanized steel or extruded aluminum frames. All low leakage dampers include vinyl blade and jamb seals.

Basics of Fan Selection

The first consideration in any fan selection is the amount of air to be moved and the resistance to this air movement. With specific performance and application criteria in mind, propeller fan selections typically require decisions based on the following criteria.

Belt Drive vs. Direct Drive

Belt drive fans offer the ability to adjust fan speed for system balancing if necessary. They also offer more flexibility in speeds and motor selections. In a cost comparison, belt drive fans are typically less costly than comparable size direct drive fans with low speed motors.

Direct drive fans are often preferred for jobs where maintenance access is difficult. Maintenance costs are generally lower with direct drive fans since there are no belts or bearings to replace and no pulleys to adjust.

Larger Fans vs. Smaller Fans

In most applications, several fans may meet the specified airflow and pressure requirements. Just as larger fans tend to turn slower and generate less sound, they also tend to have higher initial costs but lower operating costs. Smaller fans have more stable performance curves, lower initial costs, higher sound levels and higher operating costs because of their higher speeds.

Low Sound vs. High Static Pressure

Fans selected for high static pressures run at higher speeds and produce higher tip speeds resulting in higher sound levels. Conversely, in low pressure applications fans generally run at lower speeds producing lower sound levels and are recommended for sound sensitive applications.

How Accessories Affect Static Pressure

All accessory losses must be accounted for when calculating the static pressure load for a fan. In reality, dampers and damper guards actually add very little to the total system pressure when properly installed. This means propeller roof fans can be specified with low pressure capabilities (below 3/8 in. wg) when used in conjunction with properly applied accessories (as within our installation recommendations).

When fans are over-specified to compensate for losses that do not actually exist, both cost and sound levels can be higher than necessary. This results primarily from larger motors and higher tip speeds.

Motor Service Factor

Hooded roof fan motors are cooled by the airstream. With an uninterrupted flow of cooling air, motors may be operated in their service factor range (up to 20% above the motor nameplate horsepower) without damage due to overheating. Lesser overloads are recommended for applications using totally enclosed or explosion resistant motors.

Belt drive performance tables in this catalog show two RPM selections for each propeller type (L or H) at a given motor horsepower. The first selection is a 1.0 brake horsepower (Bhp) service factor. The second speed selection is at 1.2 Bhp service factor. Direct drive performance tables show Bhp levels with service factors ranging up to 1.2 Bhp. When a selection at 1.2 Bhp service factor is not desirable for the application, specify the next higher motor horsepower.

Filter Performance

For reversible models RPDRF and RPBRF, with 2-inch washable aluminum filters, use the filter performance graph below to determine the static pressure drop added by the filters. The filter loss is included in the performance data and no calculation will need to be determined for the RBF and RBCF models.

The airflow (cfm) and the desired fan size must be known to determine the pressure drop added by the filters.

Performance certified is for model RS2 supply for installation type A: free inlet, free outlet. Power rating (Bhp) does not include transmission losses. Performance ratings include the effects of appurtenances (2 inch (51 mm) filters). The sound ratings shown are loudness values in fan sones at 5 feet (1.5 m) in a hemispherical free field calculated per AMCA Standard 301. Values shown are for installation type A: free outlet hemispherical sone levels. The AMCA Certified Ratings Sound Seal applies to sone ratings only. *Sones shown apply to the highest cataloged cfm at each fan RPM. For selections at other cfm and static pressure points, refer to the CAPS computerized selection program.

Numbers in blue have a larger Bhp and require the next size larger motor.

CFM / Static Pressure in Inches WG

20-54 Direct Drive - RCS3

Performance certified is for model RCS3 supply for installation type A: free inlet, free outlet. Power rating (Bhp) does not include transmission losses. Performance ratings include the effects of appurtenances (2 inch (51 mm) filters). The sound ratings shown are loudness values in fan sones at 5 feet (1.5 m) in a hemispherical free field calculated per AMCA Standard 301. Values shown are for installation type A: free outlet hemispherical sone levels. The AMCA Certified Ratings Sound Seal applies to sone ratings only. *Sones shown apply to the highest cataloged cfm at each fan RPM. For selections at other cfm and static pressure points, refer to the CAPS computerized selection program.

Numbers in blue have a larger Bhp and require the next size larger motor.
