2 General description
2.1 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 HTM2022 + 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.

2.2 Exhauster units
The exhauster unit is basically an air compressor and consists of an electric motor, directly coupled to an
impeller fan. The motor drives the impeller assembly and the airflow is routed to provide a compression cycle.
The inlet is connected to the pipeline distribution installation and provides the vacuum and design flow rate
at the terminal units. The exhauster unit outlet is connected to the exhaust and waste anaesthetic gas is
discharged safely to atmosphere. Eventually, an optional exhaust silencer can be fitted to the discharge
opening. The electric motor and impeller assemblies are directly coupled and the motor bearings are mounted
within the motor casing. A shaft seal is fitted between the motor bearings and the impeller assembly, preventing
waste anaesthetic gas from contacting the electric motor. The impeller assembly bearings are clamped and
fixed into position with individually ground distance pieces to provide the necessary clearances for the
impeller assembly. The exhauster unit bearings do not require lubrication and the exhauster units are designed
for continuous operation.

2.3 Electric motors
The type of electric motor fitted depends upon the exhauster unit model and may require either a single phase
or three phase electrical power supply. In addition to driving the impeller assembly, the electric motor also
drives its own cooling air flow over the cooling fins. The cooling air is ambient, drawn by the exhauster from
the plant room.
2.4 Control panel
•The service diagrams shown in this section are given as example. Please use the Service
diagram delivered with the unit for up-to-date information.
•For general information on the electronic vacuum switch (type used is PN7009), please
consult also the dedicated manual 2920 7089 50 on the CD, delivered with the AGS unit.
For the factory settings, see section Pressure switch.
Simplex installation
The starter/isolator panel controls the operation of the exhauster unit and is mounted on a frame above the
exhauster unit. The panel is wired to both the electrical power supply and to the exhauster unit electric motor,
and provides facilities for the use of remote start switch panels. The panel isolation switch provides an
emergency isolation facility, which controls all electrical power to the exhauster unit, remote start switch
panels and system indication lights. A transformer is incorporated to provide a control circuit electrical power
supply at 24 V AC. A green POWER ON indicator (H1) is fitted to the starter/isolator panel and is illuminated
whenever power is available to the 24 V control and indication circuit.
The HAND/OFF/AUTO switch (S10) controls operation of the exhauster unit and provides continuous
operation when selected to HAND ("man"). When selected to AUTO, control of the exhauster unit is passed
to the remote start switch panels. Operation of any of the remote start switches activates the exhauster unit,
which will continue to run until all remote switches are selected OFF. A green RUNNING indicator (H2) is
fitted to the starter/isolator panel and is illuminated whenever the electrical power supply is available at the
exhauster unit.
The starter/isolator panel incorporates a thermal protection overload device (F21), which is selected to the
exhauster unit full load current rating. The thermal protection overload device also monitors the electrical
power supply and phase input. In the event of a fault, the overload device breaks the circuit to the exhauster
unit, which will not operate until the system is manually reset. Operation of the overload device also breaks
the circuit to the remote start switch panels, extinguishing the green RUNNING indicator. Once the fault has
been diagnosed and rectified, the overload can be reset within the panel.
Simplex and Duplex units incorporate a line pressure switch. This line pressure switch monitors the vacuum
level and provides an additional control of the remote start switch and starter/isolator panel green RUNNING
indicators.

The starter/isolator panel used in a Duplex installation has similar facilities/controls as the Simplex system
panel previously described, but incorporates additional features. An additional switch (S) enables selection
of a “Duty” pump and sets a particular exhauster unit to operate the system whilst the second exhauster unit
remains as “Stand-by”. An automatic changeover circuit is fitted to select the “Stand-by” exhauster unit when
system conditions require.

2.5 Remote start switch panels
Remote start switch panels are installed at convenient locations. A maximum of 16 panels may be installed,
connected in parallel and wired to the starter/isolator panel. The remote start switch panels consist of either:
• An illuminated Power On double pole rocker switch, a green NORMAL indicator and a red PLANT
EMERGENCY indicator.
• An illuminated Power On double pole rocker switch, a green NORMAL indicator, an amber PLANT
FAULT indicator and a red PLANT EMERGENCY indicator.
With the starter/isolator panel selected to AUTO, selection of any remote switch to ON activates the exhauster
unit and generates the vacuum within the disposal system. The green indicator light will only illuminate when
its respective start switch is selected ON and electrical power is available at the exhauster unit motor. With
Duplex installations and Simplex systems with pressure switch, the indicator light is also extinguished if the
vacuum levels fall below a pre-determined value. All remote switches must be selected OFF before the
exhauster unit will shut down. The system is designed such that the first switch selected ON operates the
exhauster unit and illuminates the green RUNNING indicator only at that panel. All other remote start switch
panel indicators remain extinguished until the respective switch is selected ON.
On Simplex installations with alarm and pressure switch, the red PLANT EMERGENCY indicator will
illuminate on all remote start switch panels if the vacuum level falls below a pre-set level when the exhauster
unit has been called, or if the overload trips.
On Duplex installations, the amber PLANT FAULT indicator will illuminate, if either pump is set to HAND,
or one of the overloads trip. The red PLANT EMERGENCY indicator will illuminate if the vacuum level
falls below the pre-set level when the exhauster unit has been called.
2.6 Drain and valve assembly
The drain and valve assembly is fitted to the lowest point of the exhauster unit outlet pipeline. The drain
removes any moisture formed by condensation. The valve arrangement enables the drain to be removed for
servicing without disrupting operation of the disposal system.
2.7 Exhaust silencer
The exhaust silencer is optional and may be fitted to the exhaust outlet point if the noise of discharged gas
proves inconvenient.
