119 × 119 mm AC case fan

The Ebmpapst 4550N is a 230 V AC compact fan built for industrial and equipment cooling. It fits a standard 119 mm square cut-out with a 38 mm mounting depth. The sleeve-bearing motor runs at 2550 rpm and draws 16.5 W at 717 mA. It is suited for engineers and system integrators who need mains-powered airflow in rack enclosures, medical devices or transport applications.

145 m³/h airflow at 44 dB

The single figure that decides fit is the 145 m³/h air delivery at the rated 2550 rpm. This sits in the middle of the 4000 N series range of 80 to 180 m³/h. The impedance-protected shaded-pole motor and streamlined blades keep noise to 44 dB while maintaining that flow rate through the pillar intake design.

For mains-powered chassis cooling

Buyers who need a 230 V AC fan with a 38 mm profile and flange mounting holes will find the electrical and mechanical match here. Those who require DC voltage operation, PWM speed control, ball bearings or higher static pressure for dense radiator stacks should look at alternative designs.

Questions about this item

How much air does the 145 m³/h rating actually move inside a typical enclosure?

The fan delivers 145 cubic metres of air per hour at 2550 rpm, providing steady airflow for component cooling in industrial or medical equipment.

What does the 230 V AC supply mean for wiring and speed control?

It connects directly to 230 V AC mains; the shaded-pole motor runs at a fixed 2550 rpm with no PWM or voltage speed control.

What clearance and mounting pattern does the 119 x 119 x 38 mm housing need?

The die-cast alloy frame measures 119 mm square by 38 mm deep with flange mounting holes for internal screw fixing.
