The serial number for a CAIRE FreeStyle Comfort unit is typically recorded in service logs, where it is listed along with the date, hour meter reading, initials, and service performed. If the serial number is rubbed off, check any service records, purchase documents, or maintenance logs where it may have been noted.

The air we breathe contains approximately 21% oxygen, 78% nitrogen, and 1% other gasses. In the FreeStyle Comfort, room air is drawn into the machine through the air intakes. It then passes through an adsorbent material called molecular sieve. This material separates the oxygen from the nitrogen and allows only the oxygen to pass through.
