Refer to Figure 1.
The Purair 130 is a high flow system with > 75 l/min, high flow rate which is used for the
extraction to atmosphere of waste anaesthetic gases exhaled from the patient breathing
system during anaesthesia.
The Purair 130 is a stand-alone system that is either ON or OFF. The float is purely a go/no-
go indicator and as such MUST ALWAYS be in the ‘MAX’ position, as described in this
manual. Any deviation from the ‘MAX’ position must be investigated following the
troubleshooting guide as in section 5.
The receiver unit incorporates a transparent window so that the position of the float and the
condition of the filter can be observed. Typical position of the float is illustrated in Figure 2.
The filter should be kept visibly clean to prevent flow restriction through it.The mesh size is
150µm.
The disposable transfer hose assembly is used to connect the receiver unit to the patient
breathing system. The disposable transfer hose compromises a 30mm male adaptor (single
patient use), a 22mm corrugated transfer tube (single patient use and a pressure relief valve.
The male adaptor is used to connect the transfer hose to the receiver unit patient inlet.
The pressure relief valve issued to connect the Purair 130 to the patient breathing system.
The pressure relief valve is not autoclaveable.
A complete Purair 130 comprises of a receiver unit/air break (designed to conform to BS EN
ISO 80601-2-13-2012), air mover , disposable (single patient use only) transfer tube
assembly with a 10cm H²O pressure relief valve, extraction / venting hose and wall venting
kit.
Pre Use Checkout Procedure
Checkout procedure to be followed daily before each use
The anaesthetic gas scavenging system should be switched on and functioning. Ensure that
the tubing is attached to the appropriate expiratory port of the breathing system or ventilator.
The top of the float becomes visible at approximately 50 l/min and reaches the top at
approximately 100 l/min

The extraction hose (6) is not to exceed 6.5 metres length
overall. Ensure there are no kinks in the minimum length.
h. Plug (7) into 13 amp 220/240V electrical socket and switch
ON control item (8).
i. With system in operation, check that the float level (9) rises above the
minimum level indicator as marked on assembly (See Figure 2).
Ensure hoses are fully extended and the float indication is
at the top.
Operating the Puair 130 AGSS
1. Connect the pressure relief valve on the disposable transfer hose
to either the patient breathing system APL valve or the breathing
circuit expiratory valve.
2. Connect the male adaptor on the disposable transfer hose to
the patient inlet on the receiving system.
3. Check that the float is visible in the float window, as illustrated in
Figure 2. If the float is not visible, refer to Section 5 – Troubleshooting.
4. Switch the Purair 130 AGSS on using the on/off switch on the
air mover enclosure.
