Prepare to be blown away by the new Jetfans! These powerful mixed-flow digital fans are 32-bit microprocessor-controlled and offer outstanding performance and value. Available in 4", 6", 8", and 10" models, Jetfans are the ideal solution for your ventilation needs. Because the motors in these fans are EC—electronically controlled—they offer very high efficiency, reliability, and controllability. They include a highly precise speed control unit that can be detached from the fan and power cord if desired.
