Sidewall Propeller Fans

Greenheck’s sidewall propeller fan line is the ideal choice for factory and warehouse applications where high volumes of air and low pressures are required. From general ventilation to industrial duty, the range of construction and performance capabilities offered in this catalog represent the most comprehensive sidewall propeller fan line in the industry.

Performance spans the range between 300 to 87,000 cfm (510 to 147,814 m3/hr) with static pressures to 1.0 in. wg (249 Pa). Fan sizes range from 8 to 54 inches (203 to 1372 mm) for direct drive and 20 to 72 inches (508 to 1829 mm) for belt drive. Regardless of fan size, performance or duty level, all Greenheck sidewall propeller fans are built to perform with the same high standards of reliability and durability.

All models are available in exhaust or supply arrangements. Propellers are available in fabricated steel, fabricated aluminum or cast aluminum. Drive frames and panels are constructed to match the level of duty and the motor size from the smallest low volume model to the largest industrial duty fan.

There is a wide variety of fans to choose from including:

Three air flow directions; exhaust, supply and reversible

Both belt drive and direct drive fans

Three levels of construction from commercial to industrial

Multiple blade designs for low sound and optimum efficiency

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 that require 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 Wall Mounting

Mounting Fan Directly to Wall

The split drawing below illustrates the typical ways of mounting fans directly to the wall when a wall housing or collar is not used.

For exhaust fans, there is a minimum dimension (M) which must be maintained between the propeller and damper or guard to achieve optimum performance (failure to meet this minimum dimension will result in loss of fan performance, increased noise and shortened fan and damper life). There is also a minimum required wall opening dimension (W.O.) to allow the venturi to fit into the wall opening.

See the chart at right for the minimum “M” and wall opening dimensions.

Motor Side Guard

Protective guards of welded steel wire completely enclose the motor and drive side of the fan. Guards are coated with Permatector, a thermal setting polyester urethane. Other paint finishes are also available. Sizes 20 and larger only.

OSHA Motor Side Guard

Protective guards of expanded metal screen in structural steel frames are available to completely enclose the motor and drive side of the fan.

Weatherhood

Weatherhoods shield wall openings and dampers from rain and snow. Weatherhoods are shipped unassembled in kit form for field assembly. Construction is of galvanized steel with wire mesh birdscreen. Mounting flanges have prepunched mounting holes. 45° turn down is for exhaust and 90° turn down is for exhaust and supply. Options include aluminum construction, insect screen and painted finish.

Damper Guard

Damper guards meet the OSHA requirements completely enclose the damper or wall openings on the discharge side of the fan. They are constructed of expanded

galvanized steel screen in galvanized steel frames. Mounting flanges have prepunched mounting holes. Options include aluminum construction and painted finish.

Dampers

Used alone or in conjunction with the wall housing or wall collar, a complete line of dampers is available for exhaust or supply configurations.

5

Standard Horizontal Mounting Option

Horizontally mounted fans are available for applications requiring vertical airflow. Typical applications include mounting fans in ductwork or plenums as transfer fans or suspending them from the ceiling in a wall housing for use as recirculation fans. Both belt and direct drive fans can be horizontally mounted. Motors can be mounted on top or on bottom with airflow up or down. Specify configuration best suited for access and service.

Horizontally mounted fans are put under different stresses than fans mounted in a wall. Construction modifications are required depending on motor location (top or bottom) and whether the fan is belt or direct drive.

These modifications may include the following:

A - Grooved shaft with snap rings (belt drive fans)

B - Motor pulley retaining hardware

(belt drive fans with motor on bottom)

C - Reinforcing angles on fan panel - not shown (all fans with motor on bottom)

D - Propeller retaining hardware

(direct drive fans with motor on top)

Wall Housing Mounting Arrangements

The wall housing is designed to reduce installation time and provide maximum installation flexibility. Attached accessories such as backdraft dampers, guards and weatherhoods may mount to either end. As a result a wide variety of configurations are available to accommodate the needs of the system designer.

The following information will help determine the correct arrangement required. When ordering specify arrangement by the drawing number 1A, 2A, 1B or 2B as shown in the diagrams below.

NOTE: Weatherhoods are strongly recommended for all configurations to help prevent moisture infiltration. Mounting flange, damper and guard ship factory mounted on all arrangements as shown except when ordered as a kit.

Mounting Arrangements for Interior Service Applications

The arrangements shown below are the most commonly used and should be considered first for most applications. The choice of flush interior or exterior mounting are based on appearance or space considerations.

Belts, pulleys and motors are serviced from inside the building with these arrangements. For applications requiring service from outside the

building, see reverse mounting arrangements below.

Mounting Arrangements for Exterior Service Applications (Optional)

Reverse mounting a wall housing simply involves installing the wall housing through the wall opening in the opposite direction of the above configurations. This results in an opposite effect on fan function. An exhaust fan in a wall housing will function as a supply fan when the housing is reverse mounted.

Example: When the exhaust arrangement shown as 1A is reversed (shown as 1A-R) the same unit now becomes a supply arrangement. The construction, fan position and mounting angle location in both configurations remain identical.

Other Options and Accessories

Electrical

Disconnect Switches

Toggle type and heavy duty disconnect switches are available for positive electrical shut-off and safety in servicing fans. The following switches are available to meet individual electrical requirements and can be factory mounted or shipped loose for field mounting. Wiring from the motor to the disconnect box is provided with factory mounted disconnect switches.

NEMA-1 - General purpose

NEMA-3R - Rainproof

NEMA 4 - Watertight

NEMA-3R & NEMA 4 - Heavy Duty

NEMA-7 & 9 - for Class 1 and Class 2 hazardous locations.

1-Point Wiring

Available when the following items are selected: common voltages on the motor and the actuator, disconnect mounted and wired and a wall housing. 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.

UL/cUL 705

1-Point wiring

Junction Box or Disconnect

NEMA-3R

and NEMA-1

All belt and selected direct drive fans with TE standard efficiency, single speed motors are available with the UL705 listing for electrical.

Extended Wiring Pigtail

Available only in conjunction with factory mounted disconnect switches, liquid tight wiring pigtails allow direct hook-up to the power supply which eliminates field wiring at 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 startup. (Field supplied motor starter with a relay is required to complete the wiring on a system using an end switch.)

Options

Coatings

A variety of special coatings ranging from enamels to phenolics are available for decorative or protective purposes. When a special coating is selected for the fan, all accompanying accessory items are also coated unless so specified. Consult your local representative for more details.

Welded and Painted Fan Construction

For applications where extra heavy construction is required, welded steel construction is available. With this option, all stationary connections which are normally bolted are welded and coated with an industrial grade paint. This option applies to belt drive level 3 fans and direct drive level 2 and 3 fans only.
