EFFICIENCY CURVES
All mechanical efficiency curves are measured in standard air conditions (1 atm, 20 °C ).
• Nominal flow rate range V
max
= 8,0 V ; V
min
= 4,5 V.
• Maximum current input I
max
= 1,0 A a 10 V.
ENY-SP-280
The minimum voltage indicated only refers to a minimum value that can be configured during the nominal flow rate calibration procedure.
In fact, during normal operation the motors can operate at lower voltages.

Specific fan power - SFP
SFP includes the consumption of the fans and controls.
The curves apply in the event of balanced flow rates.
