OEM axial fan from COMAIR ROTRON, Flight II DC family, built as a semi-custom unit for APC under part number 039453. Used as the main system fan in APC Symmetra RM and similar UPS chassis where a monitored 80 mm 12 V DC fan is required.
This fan is part of the Flight II 80 mm DC series, designed for continuous duty service in power electronics. It provides high-reliability airflow with a tachometer (RPM sense) output so the UPS intelligence module can monitor fan health.
Mechanical format matches a standard 80 × 80 × 25 mm square axial fan, simplifying mechanical replacement when servicing APC Symmetra RM and other UPS systems that specify this exact COMAIR ROTRON / APC part number.

| Flight II DC — FE12H0X-039453* | 80 × 80 × 25 mm (3.15 × 3.15 × 1.0 in) | 12 V DC | High-speed 80 mm axial fan (CFM per OEM label) | 4-wire lead with tach (RPM sense) | APC Symmetra RM & related UPS main system fan |
| Part # | Compatible Models | Notes |
| 039453 (Flight II DC) | APC Symmetra RM UPS main chassis fan (APC P/N 490-0024B) and other UPS / power systems that explicitly specify COMAIR ROTRON 039453 / FE12H0X-039453 | Use only where the exact APC / COMAIR ROTRON part is called out; system firmware monitors tach signal, so generic 80 mm fans are not recommended as substitutes. |
