SERIE AC Air performance laboratory – Sound measurement laboratory All fan data (paper and electronic) published by PLC are established by our own laboratories as per AMCA 210/85 - ASHRAE 51/85 (figure 12) standards (equivalent to ISO5801). The graphics are expressed in m³/h and in static pressure (Pa) available at the outlet of the fan. Our sound measurement laboratory with anechoic chamber is used to establish our sound level data, and enables us at all times to make useful sound level comparisons between solutions. Our software calculate apparatus sound levels as per normalized...
