The Air-Oxygen Blender has been cleaned for Oxygen Service prior to delivery.
The Air-Oxygen Blender reverse gas flow complies with clause 6 of ISO 11195.
The Oxygen Analyzer should comply with ISO 21647.
dryness and Composition for inlet gases:
Air: medical Air supply should meet the requirements of
ANSI Z86.1 - 1973 commodity specification for Air, type
1 grade D or better.
Oxygen: Oxygen supply must meet all requirements of USP
medical Grade Oxygen.
dew Point:
(ONLY for CE
requirements)
Both inlets should remain 10°F (5.55°C) or more
below the lowest temperature to which the air
distribution system equipment is exposed. At a
temperature of 25°F (-3.9°C) and a pressure of
90 psi (6.33 kg/cm 2 ) this equates to 2000 mg/m 3 .
* Accuracy of oxygen concentration will be affected if bleed is not activated at flow settings below 15 l/min for the high flow
Blender, and 3 l/min for the low flow Blender.
Specifications are subject to change without prior notice.
