G1G133-DE03-S01 ebmpapst 48VDC EC Centrifugal Blower

Description

The ebmpapst G1G133-DE03-S01 is a specialized 48VDC EC Centrifugal Blower engineered for mission-critical forced draft applications in Premix Low-NOx Condensing Steam Generators and mobile thermal systems. Driven by a high-efficiency M1G055-BD brushless DC motor with integrated electronics and maintenance-free ball bearings, this 1.4 kg unit operates on a 48 VDC supply (range 30.0 – 57.0 VDC) delivering a Power Consumption of 45 W (Input) and a Current Draw of 1.1 A at a rated speed of 2000 RPM. This High-performance unit is optimized to overcome significant backpressure in compact condensing heat exchangers, providing a Max. Air Flow of 82.4 CFM (140.0 m³/h / 2.33 m³/min) and a Max. Static Pressure of 24.47 mmH₂O (240.0 Pa / 0.96 inAq). Featuring intelligent speed regulation via PWM/0-10V control input, soft start, and locked-rotor protection, this 133 mm unit with die-cast aluminum housing and thick-film passivated rotor ensures precise gas-air premixing and high operational reliability in DC-powered industrial environments at the end.
