A Series Original Functions

❖ Auto Span Adjustment (Configurable)
*Even during auto span adjustment setting, manual span adjustment is possible. Previous oxygen concentrators required regular span adjustments (a one-push with the CAL or ADJ button in normal air). The auto span function prevents forgetting to adjust the span.

❖ Equipped with a Barometric Sensor
Previous oxygen concentrators and oxygen detectors were affected by atmospheric pressure, causing false alarms during typhoons or similar conditions. The “A” series solves this problem by including a barometric sensor. There is no impact from atmospheric pressure within the specification range.

❖ Built-in Maintenance Timer
This function reminds you to maintain the oxygen concentrator once a year, a task that is easy to forget. Gas detectors require maintenance and regular span adjustments at least once a year.

❖ Analog Output 4-20mA Compatible (Optional)
By adding “-AA” to the end of the product model number at the time of order, customization to analog output 4-20mA is possible.

❖ Sound ON/OFF Function
The sound ON/OFF function, which seems obvious but wasn’t available before, allows the use of contacts without emitting an alarm. It also allows you to turn off the start-up sound and button push sound, making it usable in places where noise is not permissible.
