Triangle Engineering of Arkansas, Inc. was founded in 1948, and quickly established itself as an industry leader in the manufacture of commercial, industrial, and agricultural ventilation products. In 2006 Triangle Engineering acquired Sound Fighter Fans of Shreveport, Louisiana. Sound Fighter Fans gave Triangle the additional dynamic of building custom-made heavy duty industrial fans, built by craftsmen to engineering and architectural specifications. Triangle Fans and Sound Fighter Fans are manufactured in a state of the art 300,000 square foot plant located in the central Arkansas city of Jacksonville. Our product is shipped worldwide to Europe, Asia, South America, Mexico, Canada, New Zealand, and Australia.
