TerraBloom 10 Quiet EC Inline Duct Fan - 946 CFM, 126W, Speed Controller

TerraBloom, an American company, specializes in creating innovative and intelligent ventilation solutions for commercial, agricultural, and residential use. We prioritize accuracy and honesty, setting us apart from 99% of our competitors. To ensure the reliability of our products, we have conducted independent lab testing on 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 versatile, used in indoor grow facilities, vertical farms, heating and cooling transfer, commercial drying, and air filtration applications. They can create negative pressure environments, exhaust odors and smoke, and intake fresh air from outdoors. Featuring a cutting-edge brushless EC Motor and dual jet type blades, our blowers deliver a high airflow rate of 946 CFM while using only 126 Watts at maximum speed. This translates to an annual operating cost of just $380 at max speed, with an average cost of $0.29 per KWH.

The ECMF-250 is HVI Certified and meets the ENERGY STAR Most Efficient 2021 Criteria. It offers unique control flexibility, allowing users to adjust speeds from 0 to 100% using the included variable speed controller without generating background noise. Users also have the option to upgrade to a wireless remote control (Model: ECMF-WR) or an intelligent thermostat speed controller with temperature programming (Model: SC-ECMF). The fan supports PWM and 0-10V controllers via a 3.5mm audio port.

Constructed with coated steel housing, this fan is resistant to rust and protects the motor and blades from damage and harsh elements, reducing maintenance requirements in demanding environments. It has an IPX4 ingress protection rating and comes with specifications including a duct diameter of 10” (250mm), airflow of 946 CFM, power consumption of 126W, noise levels of 45-65 dBA, maximum pressure of 410 Pa, dual ball bearings, dimensions of 8.3 x 11.8 x 10.8 inches, ETL Listing, and a 2-year warranty.
