The AS1 Single is an ideal air supply when portability and versatility are important. The AS1 is designed to work with any cylinder and can also have a second cylinder added to it without interrupting the air supply.


When combined with Avon-ISI’s ARAP Type-C respirators, the AS1 provides unmatched IDLH (Immediately Dangerous to Life and Health) protection.


The AS1 is well-suited for confined spaces, mining, oil, gas and marine industries.  With an airline equipped SCBA, the AS1 Single becomes a crucial extra cylinder of air.
