AeroTec™ is not a typical dock fan - it’s actually an air exchanger capable of cooling, warming or moving out toxic gasses in a trailer within seconds. AeroTec™ creates a high-velocity column of air that continually circulates fresh air throughout the entire trailer, creating a more comfortable work environment for loading dock workers. These compact dock fans require 75% less space than arm-supported fans. The aerodynamically efficient, compact design features a protective breakaway elbow tube that won't break in a collision. Loading dock fans have a high velocity split capacitor motor with thermal cutoff. Dock fans install easily using a universal mount that allows swivel and slide positioning when clearance is limited. 8' length, 115V Power Cord. 1 Year Limited Warranty.
