The RamFan EV600 and EV620 21" electric PPV turbo blowers have a variable speed system that allows continuous airflow adjustment from 1,000 CFM to 11,000 CFM. A major advantage of this system is that lower start-up power is required. Unlike rheostat based units, the IntelliSense™ speed controller uses AC to DC conversion and limits the current in-rush upon start up. This technology allows speed control that runs on GFCI circuits and generators as small as 2kW. 115V version is compatible with 20 amp GFCI circuits.
