BOX-DR - similar to BOX-D but with round connection
ideal for clean air supply, extraction or filtration in environments where low noise levels are essential - residential homes, offices, bars or restaurants, gyms
the low noise level of the fan is due to the acoustic-insulated fan casing
operating temperatures from -20 °C to +40 °C
