How loud is this 8" EC fan?
The sound output of our fans depends on
the speed selected. Please refer to the video below showing the sound
output of ECMF-200 fan at various speed levels from the lowest to the
maximum setting. The measurements of dB output are shown on the screen
in front of the unit and the microphone recording the sound is installed
5ft away from the fan.
What is included in set with ECMF fan?
1.Fan pre-wired with a 6.5ft long power cable and grounded 3-prong plug.2. Variable speed controller. 3. 16 Ft long Speed controller cable with 2 male 3.5mm TRRS jacks. 4. Installation Hardware (Screws and Anchors).
How to adjust ECMF series fan speed?
Each ECMF fan is supplied with a variable speed controller (potentiometer type). Speed controller connects to the fan via the supplied speed controller wire with 3.5mm TRRS male-to-male jacks (also known as T(ip)-R(ing)-R(ing)-S(leeve) jack). When connected, supplied speed controller allows users to select any speed between 0-100% of output according to the preferred use/noise level. If the speed controller is disconnected, ECMF fan will automatically work at 100% output.
Can an external speed controller be used to adjust ECMF series fan speed?
All ECMF series fans manufactured on 11/1/2019 or later support external speed controllers with PWM or 0-10 VDC signal types. Please verify that your speed controller or Building Management System is capable of controlling the equipment with PWM or 0-10 VDC signals.
Can I adjust the speed of this fan with a Raspberry PI or Arduino based controller device?
Yes, Raspberry PI and Arduino devices can be used to control the speed of our ECMF fans via PWM signal.
Will Rheostat Speed Controllers or Dimmer Switches work with ECMF fan?
Speed controllers designed for AC motors, such as rheostat speed controllers or dimmer switches, will not work with ECMF series fans. If you need a replacement of ECMF fan speed controllers please contact TerraBloom.
What are the requirements for the fan's operating environment?
ECMF fan can be operated in the environments with temperatures between 15°F(-10°C) to 140°F (60°C) and humidity levels not exceeding 90%. ECMF series fans have IPX4 IP Rating.
What type of ball bearing used in ECMF series fans?
ECMF fans are built with heavy-duty dual ball bearings rated for up to 70,000 hours of operation.
Can ECMF fans be used for boosting airflow in heater ducts?
ECMF can be installed in heating ducts with most modern home furnaces, however, it is important to ensure that the air temperature in the duct is not over 140°F for prolonged periods of time. Please note, fire places and fire-based heaters supply air at over 140°F, which will cause ECMF fan to trigger overheat safety switch and/or cause deformation of the impeller.
