127 mm AC case fan for industrial use

This 127 x 127 x 38 mm fan runs on 230 V AC mains power and delivers 180 m³/h of airflow at 2750 rpm. It uses a ball-bearing motor rated at 18 W and produces 44 dB of noise. The unit is built for continuous duty in industrial and commercial equipment rather than standard desktop PCs.

Suited for rack and cabinet cooling.

Engineers maintaining Siemens inverters, medical devices, rail vehicles or supermarket systems will find the voltage and mounting footprint familiar. Builders looking for a low-noise PWM fan for a home computer should look elsewhere because the fixed-speed AC design and 44 dB output are ill-suited to silent workstations.

180 m³/h airflow with 44 dB acoustic ceiling

The fan moves enough air to cool dense drive bays, inverter modules or industrial power supplies where steady throughput matters more than silence. In noise-sensitive rooms or compact cases with restricted intake, the fixed 2750 rpm speed and AC supply limit flexibility and may exceed acceptable sound levels.

Questions about this item

What mains voltage must my installation provide for the 5958 fan to run?

The fan operates directly from a 230 V AC supply, so no separate power supply or adapter is required.

Will the 44 dB noise level of the 5958 be noticeably louder than the older 5900-series unit I am replacing?

At 44 dB the 5958 sits at the same acoustic rating as the 5900 series, so perceived loudness should be comparable in the same mounting position.

How can I confirm the 5958 is delivering its rated 180 m³/h airflow once installed?

Measure the exhaust air speed with an anemometer at the outlet grille; a reading consistent with 180 m³/h through the 127 mm square face confirms the fan is performing to specification.
