Air flow device

摘要

The present disclosure is drawn to an air flow device and system for evaluating fabric integrity and cyclic stress of a media banner, and a method of simulating prolonged wind exposure on a media banner. The device can comprise a duct having an exit opening with an opening area of 100 to 250 in2; a blower in fluid communication with the duct, the blower and the duct adapted to generate an ambient air speed at the exit opening of 35 mph or more, wherein the exit opening is positioned at least 2 feet from the blower; and a programming panel electrically coupled with the blower and adapted to program and cycle operation times and air speeds.

1. An air flow device for evaluating fabric integrity and cyclic stress of a media banner, comprising:
a duct having an exit opening with an opening area of 100 to 250 in2; a blower in fluid communication with the duct, the blower and the duct adapted to generate an ambient air speed within 4 inches of the exit opening of 35 mph or more, wherein the exit opening is positioned at least 2 feet from the blower, wherein the duct has a uniform cross-sectional area from the blower to the exit opening, and wherein air flow generated by the blower exits the air flow device at the exit opening; and a programming panel electrically coupled with the blower and adapted to program and cycle variable operation times and variable air speeds including the air speed of 35 mph or more.
