Description
The SANJUN SG146HA2 is a high-performance 220VAC AC Centrifugal Blower with a 146 mm specialized impeller, specifically engineered for mission-critical cooling in Industrial Frequency Converters and specialized ventilation systems. Driven by a high-torque external rotor motor with precision dual ball bearings, this 4100.0 g unit operates within a 220 – 240 VAC range across 50/60 Hz frequencies, delivering a Max. Power Consumption of 266.0 W and a Max. Current Draw of 1.50 A at a rated speed of 1620 RPM. This High-performance unit features a forward-curved aerodynamic impeller designed for maximum static pressure, achieving a Max. Air Flow of 1000.0 m³/h (588.0 CFM / 16.67 m³/min) and a Max. Static Pressure of 45.90 mmH₂O (450.12 Pa / 1.81 inAq). Featuring a maintenance-free structure and integrated thermal protection, this IP54-rated blower is optimized for environments requiring high-pressure stability and long-term reliability in industrial VFD and power electronics systems at the end.
