Quiet EC Inline Duct Fan for Home with Speed Controller

TerraBloom is an American company that creates innovative and intelligent ventilation solutions for commercial, agricultural, and residential applications. We prioritize accuracy and honesty, and unlike 99% of our competitors, we have invested in independent lab testing for all key performance metrics of our EC inline duct fans. Our data accuracy is certified by the Home Ventilation Institute and EPA's Energy Star's Most Efficient Awards.

Our EC duct fans are utilized in indoor grow facilities, vertical farms, heating and cooling transfer, commercial drying, and air filtration applications. They can also create negative pressure environments, simulate wind, exhaust odors and smoke, as well as intake fresh air from outdoors. The fan is built with a cutting-edge brushless EC Motor and dual jet type blades, delivering a 946 CFM airflow rate using just 126 Watts at max speed. This translates to only $380 in annual operating costs for 24/7 use at max speed, using an average cost of $0.29 per KWH. Our fans do not "purge" or waste electricity at lower speeds, and the ECMF-250 is HVI Certified and meets the ENERGY STAR Most Efficient 2021 Criteria.

The EC fan offers unique flexibility of controls, allowing users to choose any speed from 0 to 100% using the included variable speed controller without creating background noise or hum at low speeds. There is also the option to upgrade to a wireless remote control or an intelligent thermostat speed controller with temperature programming. The fan also supports PWM and 0-10V controllers via a 3.5mm audio port.

The coated steel housing of the fan resists rust and protects the motor and blades from accidental damage and harsh elements, reducing maintenance in demanding applications. It has an IPX4 ingress protection rating.

The fan has a duct diameter of 10” (250mm), airflow of 946 CFM, power usage of 126W, noise level ranging from 45-65 dBA, max pressure of 410 Pa, dual ball bearings, and measures 8.3 x 11.8 x 10.8 in. It is ETL listed and comes with a 2-year warranty. Visit the store to explore more inline duct fans, extension cords, and retractable cord reels from TerraBloom.
