Having a 100% enclosed industrial fan motor is a must in most industrial environments.  A totally enclosed fan motor allows for operation at dusty and dirty job sites.  Small dirt particles can get inside the motor and destroy or shorten the life of the fan.  A enclosed motor fan also cuts down on the amount of noise output.   This allows you to run a fan where phones and conversation takes place.  TPI Industrial Fans are known for there high quality enclosed fan motors.  TPI Fans are manufactured in the USA.  TPI Industrial manufactures a variety of fans with enclosed motors to include: Pedestal Fans, Floor Fans, Workstation Fans, Wall Mounted Fans and Blower Fans.
