TerraBloom ECMF-150, Quiet 6" Inline Duct Fan With Variable Speed Controller – Ventilation Exhaust Fan For Heating Cooling Booster And Grow Tents Review

The build quality for the price is second to none. I’ve tried the popular/featured brands sold on revain and none compared to this. Powerful, compact, well built and quiet. The flow controller is not stepped and can be dialed into the flow you need. When I expand I’ll buy another one of these fans

This fan is the business. Solved so many problems for me. Perfect even for my small tent and I run it full time at about 50% . Keeps my temps in check as well as keeps strong airflow

This is a great brand for inline fans. Easy to install and complete control over fan speed. True 0-100% and very quiet. Highly recommend.

I chose this over other fans, because it’s American made. I don’t typically care about products being American made, but for some reason I felt like I wanted this to be made in America. I think the quality of components in a device like this really matters, and many American products are better built.When I opened the box, everything looked high quality. I had a sense like this product is going to perform how I want it to. I bought this to suck the hot air out of a small movie theater room. The

So good and quiet Just bought my 2nd 6”. One on half speed for my grow room air intake and one exhausting on 1/4 speed. Definitely buy no question love how the noise is little to nothing.

I own 2 of these fans for about 6 months and work great. Best 6 inch exhaust fan and trust me nice owned about 6 or 7 different brands.

The airflow is continuously variable, not stepped like an AC Infinity. For the energy usage the airflow is good. It makes good pressure and good vacuum no matter how you implement it. The propriety connectors are my only reservation (on the speed control pendant). It is useful though the unit can be used at full speed without the speed control pendant connected at all, and they provide a thread on cover to protect the port. I will purchase again when needed.

Very quite around half speed cant here it. Very powerful and lil loud on max. Great buy. Only con is speed control feels cheap but everything else feels excellent build quality. Bought 2 of them for home cieling vent. Glad i went with these!

I’ve been using bilge fans to provide simulated wind for a flight simulator but they are sleeve bearing, brushed, DC motors and wear out under sustained high RPM operation. I started looking for an alternative and found these. Early into their use but they are perfect! With electronic commutation there are no brushes to wear out and the ball bearings are rated at 70,000 hours, 8 years, continuous. The kicker is the control circuit. You can use the supplied potentiometer for manual control, but…

I was surprised when I first took this fan out of this box. It was half the size of the vivosun 6-inch fan I was using. I looked inside the fan to find tiny 4-inch fan blades. I realize now this company is pulling some dubious business practices. They took a 4-inch fan and removed the ducting flanges. So they can sell it as a 6-inch fan for more money. If you look at other 6-inch inline fans like from vivosun they actually have 6-inch or larger fan blades.It is also spinning 2x the speed of the

Much louder than I was anticipating, but it moves a ton of air. I'll try to remember to post an update a year from now (hopefully, not sooner).

Got it as an air flow solution. Purchased a year ago, running 24/7, and it's still going through cold to moderate temperatures. The noise seems to be a little loud, but I have not had another blower brand to compare it to.

These are first impressions, having just installed it as an exhaust fan for my garage. It replaced an almost new fan than put out almost no air and whistled a lot while doing. This fan is powerful, but quiet. It was also easy to install. Overall, I'm very pleased!

Quite enough on level 3 plugged into a carbon filter that I can do office work in same room without too much irritation. Level 2 kinda cycles up and down which is annoying. Didn't fit on the carbon filter of same size so I had to just secure it with duct tape.

At half power (variable switch included) it's powerful. At full power it's a hurricane. You can't go wrong installing it. very simple with a long plug, and a long extension wire to the variable switch control. I can't ask for more in an in-line vent fan.

I had bought one of these units and liked it so much I immediately ordered a second. They are perfect and the only ones I found that have a true 0-100% motor speed at this size and price point. I've been using both for about 3 months and they are ultra quiet and work perfectly!

Added the boosters into each 6” HVAC ducts going into our sunroom. My buddy hooked them up to the EAC line on the furnace board so the boosters run when the furnace blower is operating. I set the included digital controllers to #3 and increased the cfm’s from 21 to 85. Just perfect! These fans are extremely quiet and very well built. Highly recommend

This blower moves a ton of air. I used this to suck heat from my wood stove and circulate it into my HVAC system. It moves a ton of air and is very well built. Only time will tell how durable it is but everything about it is high quality. You get what you pay for here. The motor and controller are located in the unit itself and the switch is a simple potentiometer. The fan has some delay when spooling up but thats not an issue for me. Again, 350cfm is a ton of air and its pretty darn quite up…
