DC Fans

DC Fans

DC, or direct current, technology has evolved significantly in recent years, and DC fans are now used in a wide range industrial, residential, and commercial cooling applications. Direct current fans utilize motors that feature built-in permanent magnets which attract (or repel) a rotor around an axis that is paired to inverters. This energy efficient fan design also produces less noise and lasts longer than other options.
 
PUI is a leading distributor of DC fans and other forced air cooling solutions. We offer square DC fans, splash-proof DC fans, centrifugal DC fans, and counter rotating DC fans. See individual product listings for additional information and specifications.

Features & Benefits of Direct Current Fans

• Minimal EMI (electromagnetic interference)

• The most energy efficient fan option

• Low noise

• Lower voltage

• Long life

• PUI offers DC fans in sizes from 36 mm to 200 mm

Common Applications for DC Fans

Because they operate so quietly, last so long, and produce minimal interference, direct current fans are ideal for a wide range of demanding applications. Durable construction and energy efficient performance make DC fans a highly effective forced air cooling solution for everything from HVAC systems to medical devices to robotics.
