Suncourt 2-Speed Inductor Inline Duct Fan, 10 Inch Diameter, Indoor Air Ventilation

I installed this DB310E in our bonus room duct run. The bonus room duct makes three 90 degree turns before going down a rather long run then it blows into the bonus room. I've had this fan for about a month now. This has made a huge difference in the comfort of our bonus room. The outside temps are now in the 90's but we can still stay comfortably cool thanks to the booster fan. Before we had this duct fan the room temp would be in the mid 80's. I keep it running 24x7 now and so far it is running great.Installation was simple and I have it on the high speed setting and the added noise is not a problem, I still keep the TV volume at the same level.This worked great for about a year and a half but then it died.

The fit on these fans is okay but they didn't have the power I had hoped for. They might work alright to boost an individual duct but anymore than that there is just not enough power to notice a difference. I ordered 2 and started getting bad noise from 1 about a week into use. Ended up disconnecting both and am looking for a better alternative

I bought this unit to move warm air from above a wood stove 50 ft to the other end of my house. It works excellent and has definitely helped even out the temperature in our house (we only use the wood stove for heat). I wired it up to switch on with a thermostat. I ran the ducting in our attic and placed the fan halfway between the inlet and outlet and it moves a decent amount of air. You also can't here it run which is nice (and expected).The included instructions were sufficient and the product works great. It has only been in use for about 1.5 months so I am not sure about the durability of the unit.

I installed this fan yesterday. It does what it says it will do. I may be trying to supply too many rooms with this fan as I don't notice a difference in the rooms with the longer runs. Installing the fan was straightforward and only took a couple of hours.

I purchased this to help cool my master bedroom and it does a great job at moving extra air to the room. The instructions say to mount the fan at least 6 feet away from the vent to reduce any noise the fan may make. I actually have it mounted right after the split in the duct work going to the master bedroom which is about 12 feet away from the vents. The only way that I can tell that this fan is on is the increased volume of air coming from the vents. Perfect solution for my situation. Hopefully it lasts for years.

This little guy worked great for about 6 months, but now it is dead. I went to clean it since it had obviously stopped working (motor just hummed) and I expected it to be filthy inside. But in actuality it was very clean. I applied a little light machine oil to the shaft and got it to spin freely, but when I put the power to it it locked up again and in no way could be coaxed to start back up. I guess next time I'll go for something a little higher quality.

Does not work well for long duct runs. Does not perform well in my application. This would probably work installed close to the diffuser. A fan curve should be supplied in the listing.

good price; quick delivery. A bit noisy though. Does not have a connection box attached; you must add your own handy box to make connections to code.
