One of the smaller TurboXE fogging fans; the XE-500 is designed for small spaces between 25 to 45 feet in length that need the fogging capability and industrial quality of the Aquafog line. This model has a maximum fogging output of 12 GPH and can propel fog up to 25 feet. Unlike the larger four-blade units, the XE-500 utilizes a two-blade fan, making it about 30% quieter than the XE-2000.
