Simplified schematic of a AGS Duplex installation
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.
