EQUIPMENT FANS FANS FOR AC OPERATION FANS FOR DC OPERATION PAPST DC fans are distinguished by a number of essential advantages: The fan is connected to the DC supply of the equipment to be cooled and is therefore independent of the mains voltage. PAPST DC fans may be operated with the voltage reduced by as much as 50 % or increased by 25 % of their nominal voltage, which may help reduce noise. The life expectancy of a DC fan is higher than that of a comparable AC fan, independent of the bearing system, since DC fans are up to five times more efficient. DC fans powered by low voltages ( 12 or 24 V ) make elaborate safety precautions unnecessary. DC MULTIFAN Front View Side View CONSTRUCTION: fan of fiberglass reinforced plastic, with PBTP housing, PA impeller. DRIVE: electronically commutated external rotor DC motor, with electronic protection against blocking and reverse polarity. AIR EXHAUST: over struts ROTATIONAL DIRECTION: clockwise, looking at rotor. All PAPST AC fans are driven by shaded-pole motors or capacitor motors, most of which incorporate the world-famous PAPST external rotor principle. This motor construction is ideally suited for AC fans, since its outstanding advantages may be optimally realized in this application.
