Understanding Airflow Patterns (cont.)
PowerfoilPlus™
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 cool 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 can make a dramatic difference in congested areas of your facility. You can treat air like water and
scoop, direct, and channel it right where you need it most. If you are using a PowerfoilPlus fan, you will notice that it delivers air from a
much higher angle, overcoming many of the obstacles outlined below.
•
Make sure people are not hidden behind structures that 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., in a way that scoops air into the work area rather
than deflects it away.
•
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.
