Blender Differential Bypass (Optional) - Dräger WBR82 Instructions For Use Manual

PROPRIETARY AND CONFIDENTIAL DRAFT 5 Feb 04

Blender Differential Bypass (Optional)

The factory-installed, optional, blender module alarms whenever the pressure differential between the
oxygen and air supplies exceed 207 kPa (30 psi) ± 14 kPa (2 psi). When this condition occurs, the blender
continues to supply whichever gas has the higher pressure: either 100% air or 100% oxygen. This is an
audible alarm only; there are no visual indicators. If a blender is present, both sources of air and oxygen
must be connected and turned on and present to prevent the Differential Bypass alarm from activating.
NOTE:
Because this alarm is pneumatically powered, either O or air must be present for the alarm to sound.
