Description
The Fasco 70530108 GPM7.0 is a high-performance 120-240V Centrifugal Blower specifically engineered for mission-critical forced draft applications in Premix Low-NOx Condensing Steam Generators and high-efficiency burner systems. Driven by a specialized high-speed motor with maintenance-free double ball bearings, this heavy-duty unit operates on a wide voltage range of 120 – 240 VAC delivering a Max. Power Consumption of 520 W and a Max. Current Draw of 2.3 A at a rated speed of 7300 RPM. This High-performance unit is optimized to overcome significant static pressure in condensing heat exchangers, providing a Max. Air Flow of 226.6 CFM (385.0 m³/h / 6.42 m³/min) and a Max. Static Pressure of 285.53 mmH₂O (2800.0 Pa / 11.24 inAq). Featuring intelligent speed regulation via PWM/0-10V control input, soft start, and locked-rotor protection, this 36-blade unit with sheet steel construction ensures precise gas-air premixing and high operational reliability in intense thermal environments at the end.
