Introduction
AGS 510 up to AGS 3770 are blower units, used to create vacuum for the removal of waste anaesthetic gases
in theatres.
The Anaesthetic Gas Scavenging (AGS) disposal system connects to the patients breathing circuit via a
transfer and receiving system and removes expired anaesthetic gas from its source. The anaesthetic gas
scavenging disposal system is designed to comply with H HTM02-01+MDD, BS 6834:1987 and
BS EN ISO 7396-2. In order to achieve the correct performance specified, it should be used with a transfer
and receiving system manufactured to the same standard as the system is intended for, in order to ensure the
gas probe is compatible.
All flow and pressure drop values in this Instruction Book are in accordance with standard
HTM02-01 - BS6834:1987.
For HTM02-01 - EN ISO 7396-2 use 80 l/min with a 1 kPa pressure drop (max.) and 50 l/min
with a 2 kPa pressure drop (min) for high flow systems and 50 l/min with a 1 kPa pressure
drop (max.) and 25 l/min with a 2 kPa pressure drop (min) for low flow systems.
Waste anaesthetic gas, diluted by room air within the attached receiving system, is transmitted by vacuum,
which is generated by an exhauster unit. Vacuum levels within the pipeline installation and flow rates at the
terminal units are controlled by flow regulating valves (also called pressure relief valves). Waste gas is safely
discharged to atmosphere via a fixed medical gas pipeline installation. An exhaust silencer is optional.
An
AGS Simplex
consists of a single exhauster unit, operated by remote start switches and an individual flow
regulating valve.
AGS Duplex
consist of a double exhauster unit, controlled by an automatic changeover electrical control
circuit, which selects the “Standby” exhauster unit when the system conditions require. This arrangement will
operate to select “Standby” in the event of a defect, which fails the “Duty” exhauster unit, and will operate
to select “Standby” when vacuum levels fall below a predetermined figure. This type of installation may
enable the use of the selected “Duty” exhauster unit during normal usage and selects the “Standby” exhaust
unit, in addition to the “Duty” exhauster unit, to provide for maximum system demands.
