Industrial Cooling Fan 230V

The Fans K3G250-RR17-H9 is an industrial cooling fan built for continuous airflow in HVAC and machinery installations. It runs on 230 V AC power and delivers 805 m³/h at 3100 rpm with a pressure increase of 574 Pa. The 300 W motor weighs 11.8 kg and operates from -25 °C to +60 °C.

Capacity and headroom

At 300 W the unit moves 805 m³/h against 574 Pa, covering ducted systems and heat-exchanger banks that need steady static pressure. The painted black rotor surface resists corrosion in humid plant rooms. Above 60 °C ambient the motor reaches its thermal limit and output drops.

Build integration

Single-phase 230 V supply simplifies wiring in standard industrial panels. The 11.8 kg mass requires secure bracket mounting but leaves ductwork layout flexible. No scroll housing is needed for this backward-curved free-wheeling design, saving space inside enclosures.

Questions about this item

Will the 230 V K3G250-RR17-H9 run on the same single-phase supply as my existing 230 V fans?

Yes, it operates on 230 V single-phase power at 300 W, so it can share the same supply as other 230 V units.

How can I confirm the fan is delivering its rated 805 m³/h airflow after installation?

Measure the outlet flow with an anemometer; the fan should reach 3100 rpm and produce 574 Pa static pressure at the rated 805 m³/h.

Does the 11.8 kg fan ship with mounting brackets or must I source them separately?

The package contains only the fan unit; mounting brackets, wiring accessories and any scroll housing are not included and must be purchased separately.
