  • High airflow from 250 mm backward-curved impeller
  • EC motor delivers 2400 W at 6100 min⁻¹
  • CE approved for gas-condensing heating systems
  • Operates reliably from −25 °C to +50 °C
  • 400 VAC three-phase supply with 4.0 A current draw

Industrial EC Centrifugal Fan

The Ebm-Papst G3G250-MW50-01 is a 250 mm backward-curved single-inlet blower built for gas-condensing heating systems. It suits installers and OEMs who need a CE-approved EC motor running directly from a 400 VAC three-phase supply. Buyers who require a different voltage or a dual-inlet configuration cannot use this unit.

Thermals Noise and Power

The EC motor M3G112-EA draws 4.0 A at 2400 W while spinning at 6100 min-1 across 50/60 Hz. Ambient operating range spans -25 °C to +50 °C, so the fan maintains rated output in cold plant rooms and warm boiler enclosures alike. Ball bearings support continuous duty without scheduled lubrication.

Included Scope

The package contains the fan assembly only; no mounting brackets, wiring harnesses or control modules are supplied. Integrators must provide their own inlet ducting, vibration isolation and speed-control electronics compatible with the EC interface.

Questions about this item

How is the G3G250-MW50-01 mounted, and which step is often missed?

The 250 mm backward-curved single-inlet housing bolts to the duct flange; the step often missed is verifying the motor rotation arrow matches the required airflow direction before tightening.

What maintenance will the M3G112-EA motor and ball bearing need later?

Inspect the ball bearing for noise or play every 20 000 operating hours and clean the impeller blades to prevent imbalance; the sealed EC motor requires no lubrication.

At what ambient temperature does the 2400 W unit hit its thermal limit first under continuous load?

The rated ambient range tops out at +50 °C; sustained operation above this temperature triggers the motor's internal thermal protection and reduces speed.
