172×55 mm AC case fan

The SXDOOL PA55B3 is a 172 mm by 55 mm frame fan that runs directly from 100 V AC mains at 0.4 A. Double ball bearings and Class B insulation rated to 155 °C give a 50 000-hour design life. It is built for industrial enclosures, servo cabinets or legacy AC-cooled chassis where a mains-powered blower is required.

Suited for fixed-speed AC cooling

Installers maintaining equipment that already uses 100 V AC fans will find a direct mechanical and electrical match. The counter-clockwise rotation and plastic impeller replicate the original airflow direction. Buyers who need variable speed control, low-voltage DC operation or standard PC motherboard connectors cannot use this unit.

100 V AC / 0.4 A fixed input

The single decisive specification is the 100 V AC, 0.4 A rating. Only systems that supply exactly that voltage and frequency can drive the motor; no adapter or converter is included. Verify the existing nameplate before ordering.
