Industrial Centrifugal Fan — 230 VAC 460 W
The Ebm-Papst K3G280-RR03-H4 is a new industrial centrifugal cooling fan built for 230 VAC mains supply. It delivers 460 W at 2550 min⁻¹ and carries an IP55 rating for dust and water ingress protection. The unit suits machinery, HVAC and inverter cooling where robust continuous airflow is required.
Mains Voltage and Environmental Limits
Operation is specified at 230 VAC across 50 Hz or 60 Hz grids with a 2 A current draw. The motor is rated for ambient temperatures from -25 °C to 60 °C and meets CE approval with insulation class F. IP55 sealing protects the die-cast aluminium electronics housing and internal ball bearings from harsh surroundings.
Mounting and Integration Checks
Verify that your enclosure accommodates the 280 mm impeller diameter and the 84 mm motor frame within the available clearance. The 17.5 kg weight demands secure fastening to the galvanised steel support plate. Confirm that the six-blade PP plastic and galvanised impeller rotation direction matches your ducting layout before ordering.

Questions about this item
What is the difference between the K3G280-RR03-H4 and the GR31M-6ID.BF.2R designations?
Both codes refer to the same 280 mm centrifugal fan with 230 VAC supply, 460 W power draw and 2550 min-1 speed; the second is an alternative manufacturer reference.
How does the 460 W rating translate to airflow performance in a typical enclosure?
At 2550 min-1 the 280 mm impeller moves a high volume of air against system resistance; actual flow depends on ducting, filters and static pressure in the cabinet.
What mains standard does the 230 VAC 50/60 Hz input follow and what does it limit?
The fan is CE approved for 230 VAC at 50/60 Hz, limiting operation to standard single-phase mains within the -25 °C to 60 °C ambient range.
