PWB-320-FAN is a variable speed, temperature-controlled fan option for FSR's popular PWB-320 and PWB-320XL wall box series. The option adds a supplemental level of protection for the expensive gear installed in the versatile wall boxes by keeping it cool while in the wall. Thermostat controlled. Whisper quiet, the fan produces a 24dBA SPL at an 80-watt heat load.
