8’-24’ Powerfoil® X

INSTALLATION GUIDE

8’ - 24’ POWERFOIL® X

Installation Checklist Did a structural engineer approve the mounting structure? (See p. 8 for Big Ass Fans approved mounting structures.)

Are you familiar with the function and use of the safety cable? (See p. 17 for information on properly securing the safety cable.)

Will the fan be installed so that the blades are at least 10 ft (3.05 m) above the floor?

Will the fan be installed so that the blades have at least 2 ft (0.61 m) of clearance from obstructions?

Will the fan be installed so that it is not subjected to high winds (such as from an HVAC system or near a large garage door)? Big Ass Fans recommends that a fan be installed at a distance (from HVAC equipment) no less than 2x the fan’s diameter when measured from the center of the fan to the equipment. If the fan is mounted lower than an HVAC supply and return diffuser’s discharge, the fan should be installed no less than 2x the fan’s diameter from the diffuser when measured from the center of the fan to the diffuser. If the fan is mounted at the same height or higher than a downward discharge diffuser, the fan is recommended to be installed no less than 1x the fan’s diameter from the diffuser when measured from the center of the fan to the diffuser.

Will the distance between multiple fans be at least 2.5x the fans’ diameter when measured from the centers of the fans.

If installing to an I-beam, is the upper yoke the correct size? (See p. 11 for more information on installing the fan to an I-beam.)

If you ordered multiple fans, did you keep the parts for each fan together? (It is critical that the airfoils be properly matched with the motor unit.)

Do you have the correct power circuit for the fan controller? (See p. 24 for information on selecting the correct circuit/fuse for the fan controller.)

Preparing the Work Site Mechanical Installation

• A 24-ft (7.3 m) Powerfoil fan (our largest model) weighs, at maximum, 475 lbs (215 kg). A scissor lift, or other suitable means for lifting the weight of the fan, and up to two installation personnel will be required.

• Big Ass Fans can only be hung from an I-beam or angle irons. If mounting from an I-beam, the I-beam must be part of the existing building structure. For specific requirements, see installation instructions starting on p. 11. Do not mount the fan to a single purlin, truss, or bar joist. Consult a structural engineer for installation methods not covered in the manual.

CAUTION: Mount fan only to an angle iron or I-beam.

Angle Iron

I-Beam

• To reduce the risk of injury to persons, install the fan so that the blades are at least 10 ft (3.05 m) above the floor.

• The fan installation area must be free of obstructions such as lights, cables, sprinklers, or other building structure. The fan blades should have at least 2 ft (0.61 m) of clearance from any obstructions.

• Big Ass Fans recommends that a fan be installed at a distance (from HVAC equipment) no less than 2x the fan’s diameter when measured from the center of the fan to the equipment. If the fan is mounted lower than an HVAC supply and return diffuser’s discharge, the fan should be installed no less than 2x the fan’s diameter from the diffuser when measured from the center of the fan to the diffuser. If the fan is mounted at the same height or higher than a downward discharge diffuser, the fan is recommended to be installed no less than 1x the fan’s diameter from the diffuser when measured from the center of the fan to the diffuser.

• The distance between multiple fans should be no less than 2.5x the fans’ diameter when measured from the centers of the fans.

• The mounting system must be able to withstand the torque forces generated by the fan. A 24-ft diameter fan generates nearly 300 ft·lb (406.7 N·m) of torque during operation.

• Fans mounted on lightweight I-beams (common in steel buildings) could cause the beam to flex and the fan to move significantly during operation. If this flexing causes a clearance problem, we suggest installing a stiffening strut to a nearby beam.

• If the fan’s extension tube is 4 ft (1.2 m) or longer, the fan’s lateral movement must be secured using guy wires (see p. 19 for more information). If the fan is close to any building fixtures it is recommended to secure the fan with guy wires as a safety measure.

• If installing a VESDA system, refer to the VESDA Installation Guide BEFORE hanging the fan.

Electrical Installation

• To reduce the risk of electric shock, wiring should be performed by a qualified electrician! Incorrect assembly can cause electric shock or damage the motor and the controller!

• The installation of a Big Ass Fan must be in accordance with the National Electrical Code, ANSI/NFPA 70-1999, and all local codes.

• AC supply feeds for one fan controller may share the same conduit with AC supply feeds for one or more controllers.

• All unused conductors that share a conduit with the AC supply feeds must be grounded on both ends.

• If required, a local disconnect should be installed per NEC and all local codes.

• Refer to specifications on p. 24 for appropriate circuit requirements.

• Each fan requires dedicated branch circuit protection.

• To avoid damage to the VFD and fan controller, test the VFD and fan controller with a test cable before wiring the CAT 5 cable!

Understanding Airflow Patterns

Airflow with Streamlined Obstruction Obstructions on the floor tend to block the horizontally moving air. Thin or streamlined obstructions do not block much airflow, regardless of size. The air tends to flow smoothly around these obstructions, losing little momentum, and leaving only a small stagnant area behind the obstruction.

Airflow with Wide, Blunt Obstruction A wide, blunt, or flat-faced obstruction forces the air to change direction, turning upward and outward. There is a stagnant area behind these obstructions that is wider and higher than the obstructions themselves.

Overhead View

Airflow in an Enclosed Area The floor jet radiates outward until it reaches the walls. The walls deflect the jet upward. After it hits the ceiling, the upward flow is directed inward, back toward the low pressure area above the fan where it is then pulled back toward the floor. This creates a convection-like air current that gathers momentum. Once this current is established, the fan begins to move air outside of the current, escalating its cooling effects.

Airflow in an Open Area The airflow moves from the fan toward the floor.

Once the airflow hits the floor, it moves outward in all directions. When airflow is deflected off of the floor it is called a floor jet. The depth of this floor jet varies depending on the size and speed of the fan. A 20-ft (6-m) Big Ass Fan at standard speed creates a floor jet 9 ft (2.7 m) deep.

Airflow with Multiple Fans Where there are multiple fans appropriately spaced, the expanding jets of adjacent fans meet to create a pressure zone. The pressure zone acts like a wall, causing each fan to behave more like a single enclosed fan. Typically, a single fan’s performance will increase when working in conjunction with other fans.

Understanding Airflow Patterns (cont.)

Powerfoil®Plus The PowerfoilPlus hybrid airfoil creates a jet of air that flows outward from the fan at a 45° angle, ignoring floor obstructions and delivering airflow in a much broader pattern. The airflow generated from a 24-ft PowerfoilPlus fan can effectively maintain an operative temperature in an area up to 168 ft away from the fan.

The same principles of airflow apply to the PowerfoilPlus, but, when planning fan placement, consider its much larger coverage area as illustrated in the diagrams on the previous page.

Tips Below are some techniques that make a dramatic difference in congested areas of your facility. You can treat air like water and scoop, direct, and channel it to where you need it most. If you are using a PowerfoilPlus fan, you will notice that it delivers air from a much higher angle, resolving many of the obstacles outlined below.

• Make sure people are not hidden behind structures that would block airflow. This may seem obvious, but work areas are routinely blocked by shelving, crates, and machinery.

• Position large obstructions so that their smallest profile is perpendicular to the direction of air movement. For example, a sheet metal press brake might have five times the frontal area if it is facing the airflow rather than if it is turned sideways.

• Wherever possible, position welding curtains, partitions, sheet materials, etc., to scoop air into the work area rather than deflect it.

• Take advantage of the air moving near the floor by creating ground level openings in your work area. It is better to have a work area blocked by materials stacked to the ceiling with an opening below than to have low stacks 3 ft (0.9 m) to 6 ft (1.8 m) high sitting on the floor.
