G1G126-AA49-71 ebmpapst 230VAC EC Centrifugal Blower

Description

The ebmpapst G1G126-AA49-71 is a high-performance 230VAC EC Centrifugal Blower with a 126 mm impeller, engineered for high-speed industrial cooling and precision air handling systems. Driven by a high-efficiency M1G055-BD motor with integrated electronics and maintenance-free ball bearings, this 1.5 kg unit operates on a 230 VAC supply delivering a Max. Power Consumption of 75 W at a rated speed of 5000 RPM (fa). This High-performance unit achieves a Max. Air Flow of 117.7 CFM (200.0 m³/h / 3.33 m³/min) and a Max. Static Pressure of 45.89 mmH₂O (450.0 Pa / 1.81 inAq). Featuring intelligent speed regulation via 0-10 VDC / PWM control input, soft start, and motor current limitation, this unit with die-cast aluminum housing and thick-film passivated rotor is optimized for industrial VFD systems requiring advanced thermal management, though it is specifically not suitable for gas-air premixing at the end.
