Product Features

  • Our EC fan gives you a unique flexibility of controls choose any speed from 0 to 100% using the included variable speed controller without creating background noise or hum at low speeds. Or choose to upgrade to a wireless remote control (Model: ECMF-WR) or intelligent thermostat speed controller with temperature programming (Model: SC-ECMF). This fan also supports PWM and 0-10V controllers via 3.5mm audio port
  • Built with cutting edge brushless EC Motor and dual jet type blades, this blower delivers 710 CFM airflow rate using just 75 Watts at max speed. It translates into only $190 annual cost of 24/7 operation at max speed using $0.29 average cost per KWH. Our fans dont purge or waste electricity at lower speeds
  • TerraBloom EC duct fans are used in indoor grow facilities and vertical farms, heating and cooling transfer, commercial drying and air filtration applications. Our inline blowers can also create negative pressure environments, simulate wind, exhaust odors and smoke as well as intake fresh air from outdoors
