Active AGSS

WARNING
2076152-001
To avoid possible exposure to anesthetic agent, always
verify the proper operation of any gas scavenging
system. Make sure the scavenging system is not
occluded.
There are several versions of the optional active Anesthesia Gas
Scavenging System (AGSS) available depending on the hospital's
type of waste gas disposal system.
Each version has a 1.2 liter reservoir to capture peak exhaust flows
that briefly exceeds the extract flow rate. The disposal system
normally entrains room air through an air brake, but will spill from this
port during extended periods of high exhaust flow. Its effectiveness is
limited by the extract flow of the particular active AGSS device.
• The active high flow system is for use with low vacuum (blower
type) disposal systems. This requires a system capable of
providing a continuous nominal flow of 50 l/min. An alarm shows
on the display when the flow is out of range. If the alarm shows
high flow, the AGSS flow may be adjusted down to eliminate the
alarm condition. If the alarm shows low flow, the AGSS flow may
be increased to eliminate the alarm condition if the hospital
extract system is able to meet the AGSS flow needs.
• The active low flow system with the vacuum DISS connector is
for use with high vacuum disposal systems. It requires a vacuum
system capable of a continuous nominal flow of 25 l/min at 300
mmHg (12 inHg) or greater vacuum pressure. An alarm shows
on the display when the flow is out of range. If the alarm shows
high flow, the AGSS flow may be adjusted down to eliminate the
alarm condition. If the alarm shows low flow, the AGSS flow may
be increased to eliminate the alarm condition if the hospital
extract system is able to meet the AGSS flow needs.
• The active low flow system with SIS EVAC connector is for use
with high vacuum disposal systems. It requires a vacuum
system capable of a continuous nominal flow of 25 l/min at 300
mmHg (12 inHg) or greater vacuum pressure. An alarm shows
on the display when the flow is out of range. If the alarm shows
high flow, the AGSS flow may be adjusted down to eliminate the
alarm condition. If the alarm shows low flow, the AGSS flow may
be increased to eliminate the alarm condition if the hospital
extract system is able to meet the AGSS flow needs.
• The active low flow system with a 12.7 mm hose barb connector
is for use with low vacuum disposal systems. It requires an
external system with flowmeter.
• The active low flow system with a 25 mm barb connector, is for
use with low vacuum disposal systems. It requires an external
venturi/ejector system with 25 to 50 l/min extract flow. An alarm
shows on the display when the flow is out of range. If the alarm
shows high flow, the AGSS flow may be adjusted down to
eliminate the alarm condition. If the alarm shows low flow, the
AGSS flow may be increased to eliminate the alarm condition if
