AC axial fan for rack cabinets

The Ebm-Papst DV4650-470 is a 230 V AC axial fan built for 19-inch rack cabinets and industrial enclosures. It runs directly from mains voltage at 50 to 60 Hz without an external power supply. The 119 by 119 by 38 mm frame fits standard fan cut-outs in server and network hardware.

Suited for fixed-speed mains cooling

This unit suits installers who need a simple two-wire AC fan with ball-bearing reliability and a rated life of 40000 hours. It is not for builders who require PWM speed control, low-voltage DC operation or a standard PC three- or four-pin header.

230 VAC two-pin power interface

The fan connects through a two-pin mains lead that plugs directly into 230 VAC panel wiring or an IEC inlet. No motherboard fan header or DC converter is involved, so the electrical interface alone determines whether this model fits the target enclosure.

Questions about this item

How do I verify the DV4650-470 is running correctly after installation?

Confirm the fan spins smoothly, moves air through the 119 mm frame, and draws approximately 100 to 110 mA at 230 V; the ball bearing should operate without grinding noise.

What comes in the box with the DV4650-470 and what must I source separately?

The unit includes the axial fan with a 2-pin power lead; mounting screws, a 230 V power cord, and any required grille or filter are not supplied.

Which version of the DV4650-470 should I choose for a standard 119 mm cabinet cut-out?

The single listed model DV4650-470 fits a 119 x 119 x 38 mm opening, runs on 230 V at 50 to 60 Hz, and delivers 94.2 CFM at 46 dB.
