K3G250-RR03-H4 industrial centrifugal fan
The K3G250-RR03-H4 is a 230 V single-phase centrifugal fan built for industrial cooling and HVAC systems. It delivers 705 m³/h airflow at 486 Pa total pressure rise, driven by a 245 W motor running at 2900 rpm. Facilities engineers and maintenance teams specify it for ducted ventilation, equipment enclosures and process-air circuits.
Painted rotor, external-rotor motor, compact build
The backward-curved impeller runs without a scroll housing, saving installation space and reducing ductwork complexity. An external-rotor motor places the windings inside the airstream for continuous cooling, while the black-painted rotor surface resists corrosion in humid or chemically exposed environments. The unit weighs 11.8 kg and operates reliably from -25 °C to +60 °C ambient.
Replaces worn AC centrifugal units in fixed
When an existing 230 V AC fan of similar diameter and pressure curve reaches end of life, the K3G250-RR03-H4 drops in with matching mounting points and electrical connection. The upgrade is worth it when downtime costs exceed the fan price, when noise reduction matters, or when the wider temperature range prevents seasonal failures. Not for builders needing variable-speed EC control or fans with integrated scroll housings.

Questions about this item
What airflow does the 230 V K3G250-RR03-H4 deliver at 2900 rpm?
It moves 705 m³/h of air at 2900 rpm on 230 V single-phase supply.
What are the physical dimensions and mounting requirements for the 11.8 kg K3G250-RR03-H4?
The unit weighs 11.8 kg and uses a backward-curved centrifugal impeller designed for free-wheeling operation without a scroll housing.
How is the K3G250-RR03-H4 wired and what common mistake should be avoided?
Connect the 230 V single-phase supply directly to the external-rotor motor terminals; do not add a scroll housing, as the backward-curved blades are built for free-air operation.
