Note:
1). The above 1/3 octave spectrum datum is based on C/T 50°C,E/T 0°C, with R22.
2). For all compatible refrigerants of R22, R134a, R407C and the working conditions acceptable in limitation of Hanbell screw
compressors, it has very similar value at all respective bars as above Sound Power Level chart with ±2dBA tolerance of OVERALL
value at any working condition by any refrigerant.
3). The above datum is based on ISO-2151 to be measured.
