Rexing

Rexing DV4600-492 120mm 115V AC industrial cooling fan

SKU CH-MTZM-TAVWZ MPN DV4600-492

A 120 mm axial cooling fan with ball bearings runs at 2650/3100 RPM on 115 V AC for cabinet ventilation

  • Ball bearing for reduced friction and longer life
  • 2650/3100 RPM maximum speed delivers strong airflow for cabinet cooling
  • 115 VAC 50/60 Hz compatible with standard industrial power
  • 18/19 W power draw keeps energy use low
  • 120 × 120 × 38 mm frame fits common Rittal cabinet cut-outs

Industrial 120 mm Axial Fan

The Rexing DV4600-492 is a 120 mm axial cooling fan built for 115 VAC industrial environments. It fits standard 12038 mounting holes and uses a two-pin power connection for direct mains wiring.

Ball-bearing thermals at 18/19 W

Dual-speed operation runs at 2650 RPM on 50 Hz and 3100 RPM on 60 Hz while drawing 18 W or 19 W respectively. Current stays at 220 mA or 240 mA, keeping heat output low inside sealed cabinets.

Replaces legacy Rittal cabinet fans

This unit serves as a drop-in replacement for worn Rittal cabinet fans of the same 120*120*38 mm footprint. The jump is worthwhile when the original bearing noise rises or airflow drops below spec.

Questions about this item

How do I mount the 120mm fan in a Rittal cabinet and which step is often missed?

Align the 120*120*38MM frame with the cabinet cut-out, secure all four corners with screws, then connect the 2-Pin plug to the 115VAC supply; the step most often missed is verifying the 50/60Hz frequency match before powering on.

What maintenance will the ball-bearing fan need over time?

The ball-bearing design requires no lubrication; plan to clean dust from the plastic blades and intake area periodically and replace the unit if airflow drops or noise rises above normal 2650/3100 RPM operation.

At what point does the 19W motor hit its thermal limit during continuous running?

The fan is rated for continuous duty at 115VAC drawing 240/220mA; the first limit reached under sustained use is the maximum speed ceiling of 3100 RPM, beyond which the motor cannot accelerate further.
