There are three circuit adapters: 

 

 

Adapter   

 

For use with 

1 

Single limb leak 

 

Single limb circuit with intentional leak or mouthpiece circuit 

2 

Single limb   

 

Single limb circuit with expiratory valve (expiratory valve integrated into the circuit) 

3 

Double limb   
(Astral 150 only) 

 

Double limb circuit (expiratory valve integrated into the adapter) OR single limb circuit with 
intentional leak or mouthpiece circuit 

A Learn Circuit should be performed after any change of circuit. Astral will provide accurate therapy as long as the Learn Circuit 
is completed. Refer to Learn Circuit (see page 44) for further information.
