Gas Supply Pressure ............. The gas supplies must provide clean, dry, medical grade air
and oxygen at a pressure of 30 to 75 PSIG (2.0 to 5.2 BAR).
Air and oxygen must be within 20 PSI (1.3 BAR).
Optimal performance is achieved at 50 PSIG inlet pressures.
Pressure Drop ......................... Less than 6 PSIG (0.4 BAR) @ 50 PSIG (3.4 BAR)
supply pressures and 10 LPM flow rate
Sensor Bleed Flow ................................. 0.1LPM LPM @ 50 PSIG (3.4 BAR)
Bleed Flow (toggle ON) ....................... 3 LPM for low flow blender (R229P01) and
13 LPM for high flow blender (R229P02)
Outlet Flow Range ......................... 0-30 LPM for low flow blender (R229P01) and
2-100 LPM for high flow blender (R229P02)
with inlet pressures at 50 PSIG (3.4 BAR)
Mixed Gas Stability* Ambient Operating Conditions ......................... ±1% oxygen
Operating Temperature Range ............................ 59°F to 104°F (15°C to 40°C)
Relative Humidity Range .................................... 0-95%, non-condensing
Ambient Storage Conditions Temperature Range ............... 5°F to 122°F (-15°C to 50°C)
Flowmeter accuracy** .............................+/-10% of indicated value or 0.5 LPM
whichever is greater, with inlet pressure set to 50PSIG.
*The delivered oxygen concentration will remain constant within ±1% of the set point value with
constant inlet pressures. The displayed value may vary more than this due to sensor accuracy,
age, environmental conditions and length of time since last sensor calibration.
**Position the device such that the flow meters are vertical to ensure accuracy.
8.2 Alarm Specifications
Pressure Diffential Alarm Activation ......................... When supply pressures differ
by 20 PSI (1.3 BAR) or more alarm is activated
Low Oxygen Alarm Range: ........................ 15%-99% (>1% lower than high alarm)
High Oxygen Alarm Range: ...................... 16%-100% (>1% higher than low alarm)
(according to IEC 60601-1-8 Audible Alarms in Medical Equipment)
