We invite you to learn about Waterline Big Fan more intimately.
Waterline HVLS Fans (Big Fan) have a unique blade contour design that varies along its length. This helps create a more complete, more encompassing airflow coverage beneath the fan.
The tapered & twisted design of the fan blade compensates for the substantial velocity differences that stretch from one end of the blade to the other. It ensures the blades produce the same amount of airflow across the entire length of the blade. (See below diagram).
Contrast this to the commonly found extruded blade designs of other makes where the blade contour is uniform along the length of the blade, the area directly beneath the center of the fan will have much lower air velocity. This causes an empty air ‘hole’ effect below the fan. (See below diagram)
When blade contour is uniform along the length of the blade as in the case of aluminum extrusion design, an area directly below the fan has no airflow being felt.
Compensates for the substantial velocity differences that stretch from one end of the blade to the other. As a result, air flow is even throughout the entire area covered.
The precision-milled fan hub and fan strut pieces ensure a flawlessly fitted connection that prevents excessive fan blade movement. A uniquely designed concave-convex joint between the fan hub and fan strut also boosts security while a vibration dampening material is used to eliminate stress on the fan hub. The result is a very strong and heavy duty blade-to-hub connection that makes the fan blade impossible to depart from the fan assembly.
4 Guy wires are installed to keep the fan stable without excessive oscillation during operation.
In the unlikely event that the fan blade is dislodged, it will be secured to the fan assembly by this Anti-drop steel cable.
2 thick multi-strand steel wire is used to loop the entire fan over the roofing structure to prevent it from being dislodged.
