Dedicated Condensing Boiler Fan
The Fans G3G250-GN17-01 is a new centrifugal cooling fan built specifically for condensing gas boilers. It uses an external rotor motor design that integrates the motor within the impeller for compact installation. The unit suits HVAC professionals and maintenance teams replacing OEM combustion-air blowers in compatible boiler models.
Thermals Noise and Power Draw
Rated for continuous operation from -20 °C to 60 °C ambient temperature with a flow-medium range of 0 °C to 60 °C. The single-phase motor runs on 230 VAC across a 208–240 VAC range at 50/60 Hz, drawing 5.7 A at 208 V. Power consumption is 1150 W at a nominal speed of 4800 rpm, with the motor position providing forced electronic cooling.
Sustained Load Behaviour
The external rotor construction ensures optimum motor cooling during extended duty cycles rather than short bursts. Speed is fully controllable via analog or serial interface for precise airflow management up to 35000 m³/h. Sturdy steel-plate construction supports durability in permanent heating-system installations where reliable combustion-air delivery is critical.

Questions about this item
How do I wire the single-phase 230 VAC motor and what is the common mistake?
Connect the 1~ motor to a 208–240 VAC supply at 50/60 Hz; the step often missed is confirming the line voltage is within range before applying power, because the fan draws 5.7 A at 208 V and 1150 W.
What maintenance will the G3G250-GN17-01 need over time?
The external-rotor motor uses forced electronic cooling, so the main upkeep is keeping the impeller and inlet free of dust and debris to maintain airflow up to 35000 m³/h.
What thermal limit is reached first during continuous operation?
The maximum ambient temperature of 60 °C and maximum flow-medium temperature of 60 °C are the primary limits; sustained operation above either will trigger thermal protection.
