Outputting 1.4 kW (1.9 hp), the RAMFAN EX150Li is the world’s most powerful battery powered positive pressure ventilation fan. It reigns superior to all plug-in electric, and far beyond all other battery-powered, PPV fans on the market. This is made possible with the Intellisense™ E3 power controller, with intelligence to safely delivery sustained high power, precision motor control, simultaneous dual battery charging, and more.
This level of power requires special battery pack designs to account for the sustained runtime at high-discharge currents. The EX150Li is fuelled by two RAMFAN® 52V Intelligent Battery Packs, totalling 832 Wh. This is the most powerful battery system in the fire service, other than the truck batteries themselves.
