Industrial 380 V 120 mm fan

The Fans 4C-380HBDimensions is a 120 x 120 x 38 mm case fan rated for 380 V operation. It delivers 89 CFM of airflow at 2650 RPM using an aluminium alloy frame and high temperature resistant plastic blades. The oil bearing motor uses B grade insulation rated to 75 degrees Celsius.

Sustained airflow at 25 W

Under continuous load the fan draws 25 W and maintains its rated speed without thermal throttling. Insulation resistance exceeds 800 megaohms and the unit withstands 2300 V for one minute with leakage current below .5 mA. The anti corrosion aluminium die casting frame resists humidity during extended operation.

46 dB noise at 21 W typical

In normal use the fan runs at 46 dB A while consuming approximately 21 W. The cover pole motor structure and black baking varnish finish contribute to stable acoustic performance. Net weight is 500 g and the compact 12038 form factor fits standard mounting points.

Questions about this item

How much noise does the 4C-380HB produce at 2650 RPM during continuous operation?

The fan generates 46 dB-A at its rated speed of 2650 RPM, drawing 25 W or 21 W depending on load while moving 89 CFM of air.

What power source and mounting hardware are required to install this 380 V aluminium-frame fan?

A 380 V AC supply is needed; the 120 × 120 × 38 mm aluminium die-cast frame uses standard 120 mm mounting holes, so four case screws are the only extra parts.

Will the oil-bearing motor and B-grade insulation rated for 75 °C survive in a chassis alongside legacy components that run hot?

The motor uses B-grade enamel wire rated to 75 °C, insulation resistance exceeds 800 megaohms and it withstands 2300 V for one minute, so it tolerates elevated case temperatures.
