- The performances above were measured under conditions of air temperature 20 °C and atmospheric pressure 1,013mbar.
- The allowable tolerance of the performance value is +10%
- The sound level was measured at a distance of 1.5m with the fully open inlet and outlet ports.
- Anti-corrosive and explosion-proof treatments can be applied upon request.
Performance Curve
- The continuous operation can be made at a point below the curve, however, the continuous operation nearby the rated pressure point may cause a motor breakdown.
In the case of the continuous operation close to the rated pressure, it is strongly recommended to use the pressure-relief valve. See accessories, page 61.
- The allowable tolerance of the performance value is ± 10%
