Description
The Fasco 70530110 GPM10.0H is an industrial-grade 380-480V Centrifugal Blower specifically engineered for mission-critical forced draft applications in high-capacity Premix Low-NOx Condensing Steam Generators and burner systems. Driven by a high-efficiency three-phase motor with reinforced double ball bearings, this heavy-duty unit operates on an industrial 380 – 480 VAC supply delivering a Max. Power Consumption of 2600 W and a Max. Current Draw of 5.5 A at a rated speed of 6700 RPM. This High-performance unit is optimized to overcome massive static pressure in utility-scale condensing heat exchangers, providing a Max. Air Flow of 647.4 CFM (1100.0 m³/h / 18.33 m³/min) and a Max. Static Pressure of 662.81 mmH₂O (6500.0 Pa / 26.11 inAq). Featuring intelligent speed regulation via PWM/0-10V control input, soft start, and locked-rotor protection, this 42-blade unit with rugged die-cast aluminum construction ensures precise gas-air premixing and high operational reliability in intense thermal environments at the end.
