Our popular PWB WALL BOXES are holding more and more equipment. Everything from digital matrix pieces, extenders and much more is going into our wall boxes. You can now protect those expensive pieces by adding our new fan! This whisper quite fan is a thermostat controlled variable speed fan. As the heat inside the wall box rises, so will the speed of the fan, keeping those expensive pieces at a safe temperature.
The variable speed PWB-320-FAN is thermostat controlled. As the heat inside the wall box rises, so will the speed of the fan, keeping equipment inside at a safe temperature. It’s designed to run at a minimum speed up to 96° F , increasing linearly to full speed at 104° F, maintaining an internal box temperature below 104°F with a 100-watt thermal load and thermal transport of 340 BTU/Hr with a 18° F temperature rise. Whisper quiet, the fan produces a 24dBA SPL at an 80-watt heat load. For best performance, use the upper mounting locations to aid natural convection airflow.
