I removed the base and mounted it between two new end plates in a 8x12 rectangular duct. Tied the power to the fan control thermostat circuit via relay so any time the HVAC was on the aux blower would be also. I really like the speed control, allowed me to get just the right bonus flow to the distant room. It comes with a digital and a potentiometer (rotary) type of controller. I used the digital one. Both retain the setting between power cycles. I have it set to 3 (of 8) and can barely hear the blower, even when right under it. It has about a ~15 foot control cable and 6 foot power cord. it also comes with a short breakout control cable if you want to make your own controller, with a tachometer signal available, which I didn't need or use. My only concern is the 140F max temperature rating of this unit, but I don't think my heater will violate it. Review: Quiet and powerful - well designed. - I am an HVAC biz owner that used the 8” fan to feed two 6” branch ducts (with an 8” intake). I turned my customer’s unusable bonus room above their garage to the coldest room in the house when it was 95 degrees outside. That was at a 75% setting. Might have to turn it down a touch! With the manual control it will always come back on if there is a power outage or you can hook it into a timer or relay control. Fan was nice and quiet and seems very well designed. I cannot account for longevity as I installed it and left. Time will tell. Fan starts out slow and Ramps up - a nice feature. I was testing it on my kitchen counter when it arrived to see how it performed. When it first came on I thought “there is no way this is 700 cfm....then it ramped up and nearly blew everything off my counter and started skating across the granite. Yeah, that’ll do! ## Features - Versatile Applications: TerraBloom EC inline fans are versatile, and used in indoor grow facilities, vertical farms, heating/cooling transfer, drying, air filtration, and more.

Note: the fan body would not be in the steam area.** A: In the current version this fan will not work for steam movement, you will exceed max humidity limit of 90%, and steam will harm the electronic components. The fan will fail prematurely and the warranty will be voided. We are working on waterproof version with external PCB which would work in environment with humidity over 90%, stay tuned for the release in the next 6 months. **Q: both ends are of the same "sex" and also of the same sex as to what I want to connect. What would be the appropriate connector?** A: if I recall correctly, an 8" duct will fit right over the fan. Just make sure the duct is uncrimped. Flexible duct can do the same thing. **Q: Is the remote controller infrared or does it use radio frequencies?** A: It uses 433 MHz frequency ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great fan, quiet. *by D***E on November 1, 2023* I used this to boost the HVAC to a distant room that was poorly regulated.

I needed to put a booster fan in the ceiling return air vent to balance out the rooms. I placed this unit in the flexible duct located in the attic. This unit is probably overkill for my need, and an expensive option, however I required remote control and variable speed, and this was the only option I could find. The unit is solid built and quiet. There is noise, but it comes from the rushing air as it passes over the grill grate, the noise is not from the motor, that part is very quiet. It comes with plenty of mounting hareware a long cord for the on/off/control switch. I hope it can withstand staying in the attic in our florida heat, I'll post back if it has heat issues. ## Frequently Bought Together - TerraBloom ECMF-200, Quiet 8" Inline Duct Fan with 0-100% Variable Speed Controller, Air Tight Metal Casing, Energy Efficient EC Motor.
