The ventilator works normally under supply pressure of 280 to 650 kPa. Supply pressure of
less than 280 kPa can impair the performance of the ventilator and even cease ventilation.
Supply pressure between 650 and 1000 kPa can impair the performance of the ventilator but
will not cause any hazard arising from high pressure gas.
