Reviews Negative Pressure Fan

TerraBloom ECMF-315, Quiet 12' (313mm OD) Inline Duct Fan with 0-100% Variable Speed Controller, Air Tight Metal Casing, Energy Efficient EC Motor.

  • 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.
  • Built with cutting edge brushless EC Motor and dual jet type blades, this blower delivers 1662 CFM airflow rate using 260 Watts at max speed. It translates into only $660 annual cost of 24/7 operation at max speed using $0.29 average cost per KWH. Our fans don’t “purge” or waste electricity at lower speeds..
  • Our EC fan gives you a unique flexibility of controls – choose any speed from 0 to 100% using 2 (digital and analog) included 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 supports 3d party PWM and 0-10V controllers via 3.5mm TRRS port.
  • Coated steel housing resists rust, protects motor and blades from accidental damage and harsh elements to reduce maintenance in demanding applications. This fan has IP64 ingress protection rating.
