Industrial Centrifugal Fan 500mm 400V
This 500mm centrifugal fan from ebmpapst delivers air flow up to 35000m3/h for industrial cooling systems. It operates on three-phase 400V AC power at 50/60Hz with a 2600W motor running at 1700RPM. The external rotor motor design provides compact integration and forced electronic cooling for continuous duty.
Upgrade From Belt-Drive Or Smaller Axial Units
The direct-drive EC motor replaces belt-driven blowers and smaller axial fans where higher static pressure and 100% speed control via analog or serial interface are required. The jump is worth it when ambient temperatures range from -25°C to 60°C and the application demands plug-and-play start-up with matched open-loop control components.
Integration Into HVAC And Process Cooling
The sturdy steel-plate housing fits ducted installations without a separate scroll housing when used as a free-wheeling backward-curved unit. It needs a 380-480VAC three-phase supply drawing 4.0A and frees up space by mounting the motor inside the impeller. Buyers who need a built-in scroll housing or single-phase power should verify compatibility before ordering.

Questions about this item
What clearance does the 500 mm impeller need for free-wheel operation?
The backward-curved blades run without a scroll housing, so allow unrestricted airflow on both sides of the 500 mm rotor diameter.
How do I wire the three-phase 400 VAC supply and the speed-control signal?
Connect L1, L2, L3 to the 380–480 VAC 50/60 Hz mains and use the analogue or serial interface for 0–100 % speed control.
When should I plan to replace the external-rotor motor bearings?
The M3G150-FF motor is rated for continuous duty from -25 °C to 60 °C; inspect bearings at major service intervals and replace if vibration or noise increases.
