(1) Corresponds to "Volume Flow Rate" (ISO 1217, third edition.
     Measured by means of an orfice plate inserted in a circular cross section conduit running full (according to ISO 5167-1
     Guaranteed with a tolerance of +/- 4%
(2) Measured according to PNEUORP PN8NTC2,2 test code (ISO 9614,2 sound intensity scanning method).
     The emission sound pressure level refers to free field conditions at 1 meter distance (operators position).
     A total correction factor for uncertainties of 3 dB has to be added to conform to the test code.
     Possible noise from discharge line, accessories and/or ancillary equipment is not included.
