Fans G3G250-GN44-01 2101 Pa EC Gas Furnace Fan

SKU CH-SNRJ-DED95

Centrifugal EC fan delivers up to 35000 m³/h airflow at 2101 Pa static pressure for gas furnace applications

  • High static pressure of 2101 Pa for demanding furnace airflow
  • EC motor draws 860 W at 4500 rpm for energy-saving operation
  • Wide 208–240 VAC input range suits 50/60 Hz supplies
  • Operates reliably from -20 °C to 60 °C ambient temperatures
  • Backward-curved centrifugal impeller delivers up to 35000 m³/h airflow

Purpose-built furnace airflow

The G3G250-GN44-01 is an EC centrifugal fan designed for gas-furnace installations that need reliable air delivery. It suits HVAC technicians and facility managers replacing or specifying OEM combustion-air or distribution blowers.

Thermals and electrical profile

The motor runs on 208–240 VAC single-phase at 50/60 Hz, drawing 4.8 A at 208 V with a power consumption of 860 W. Speed is fixed at 4500 min-1, and the unit is rated for ambient and media temperatures from 0 °C to 60 °C, with a minimum ambient of -20 °C.

Integrated control and durability

A 0–10 V or serial interface provides 100 % speed control without external VFDs, simplifying commissioning. The external-rotor construction forces cooling air over the motor windings, while the steel housing and backward-curved impeller resist deformation under 2101 Pa static pressure.

Questions about this item

How do I wire the EC fan for 230 VAC single-phase power and what is the common mistake?

Connect live, neutral and ground to the terminal block for 208–240 VAC 50/60 Hz; the step often missed is providing the 0–10 V or PWM speed-control signal, otherwise the fan runs at fixed 4500 rpm.

Which component will need replacement first and what is its rated life?

The EC motor bearings are the primary wear item; ebm-papst rates them for 40 000 hours at 40 °C ambient, so plan replacement around that interval.

What thermal limit triggers protection first during continuous high-load operation?

The electronics trip when ambient or airflow temperature reaches 60 °C, which occurs before the 2101 Pa pressure curve drops off.
