Acoustic Metal Box Fans
The Acoustic Metal Box Fans are designed for use within extremely quiet environments where keeping noise levels to a minimum is incredibly important. These fans feature an incredibly lightweight and heavy-duty metal casing, along with all appropriate connection ports for ducting and filters. The fan within the box is either mains controllable or can be controlled by a separate fan controller. Therefore this will give you full control over both the fan speed and the airflow received through the system.
