Industrial airflow for demanding cooling

The ebmpapst M4Q045-CA03-51Current is a 230 V centrifugal fan built for medical, rail, industrial and new-energy vehicle equipment. It delivers up to 3500 m³/h airflow from a compact external-rotor motor with a sturdy steel housing. The unit suits engineers who need reliable forced-air cooling in tight enclosures.

Simple integration with full speed control

The fan supports 100 % speed control via analog or serial interface and offers plug-and-play start-up with matched open-loop components. Oil bearings and a 1.1 kg weight require secure mounting; the dual 50/60 Hz rating means speed shifts between 1300 and 1550 RPM depending on supply frequency. Verify voltage and control wiring before powering.

Dual-power headroom for variable loads

At 36 W the motor handles peak cooling demand, while a 10 W low-speed mode maintains airflow with reduced energy draw. Current ranges from 0.22 A to 0.25 A across the two operating points. The design covers continuous duty in harsh environments but is not intended for low-voltage PC chassis or battery-powered builds.

Questions about this item

How do I verify the fan is running at the correct 1300 or 1550 RPM after installation?

Check the tachometer output or motherboard monitoring software; the fan should report 1300 RPM at 50 Hz and 1550 RPM at 60 Hz when operating at full speed.

What comes in the box with the M4Q045-CA03-51 and do I need a separate power cable?

The fan unit is supplied with its integrated lead for direct 230 V connection; no extra power cable is required, though mounting screws are not included.

Should I choose the 36 W or 10 W operating mode for my cooling needs?

The fan draws 36 W at 50 Hz and 10 W at 60 Hz automatically; you do not select a mode — the power consumption follows the supply frequency.
