 Performance curves 

 

 Performance range

 
 
 
Performance curves for inlet pressures <160 mbar       only available for 2BE4 30, 40, 50, 60.
 
The performance range are based on operating conditions with saturated  100 % relativer air at a temperature of 20 °C (68 °F), operating water at a temperature of Feuchte und 20 °C, 15 °C 15 °C (60 °F), and a discharge pressure of 1013 mbar (29.92 in Hg abs.).
Tolerance + 5 % for inlet pressure ≥ 250 mbar, acc. to PNEUROP. Toleranz + 5 % ≥ 250 mbar, PNEUROP. Calculation of individual performance curves is done acc. to individual
 Sound pressure level 
 
 

Type / Typ 2BE4 ...	Surface sound pressure level  and sound power level
	LpA [dB(A)]	LWA [dB(A)]
30. / 32.	75 - 82	91 - 98
40. / 42.	77 - 86	94 - 103
50. / 52.	72 - 82	90 - 100
60. / 62.	76 - 91	95 - 110
67. / 72.	76 - 91	95 - 110

The noise levels are measured on bare machines in accordance with EN ISO 2151 and EN ISO 3746 (not including noise emitted from piping and auxiliary equipment). This corresponds to the normal operational state. Values refer to standard rotational speed, inlet and discharge pressures. Values that are specific to a purchase order are available depending on the scope of the order. Actual noise levels can be higher at working place due to background noise and conditions of installation.
