Aeraulic curves (air flow/pressure) have been established on SIROCO
test benches. Nominal values are given at zero back-pressure (0 Pa).
Ventilation test voltage is 13 Volts (12V nominal). Ventilation test
voltage is 26 Volts (24V nominal).
Tests were performed in SIROCO and values are given at nominal air flow, without helmet concerning roof ventilators.
