Alsident System A/S - Graphs for reading a pressure drop in our Alsident System extraction arm at a certain air volume. Also the sound level is found in the graphs
All our systems have been tested by the Danish Technological Institute regarding pressure drop through the extraction arms and the noise level. In the charts below, you will find a graph for reading the results. The measurements have been made on different models of the system and in 3 different positions. The result in the graphs show an average of the measurements.
