AC Infinity RAXIAL S8, Inline Booster Duct Fan 200mm with Speed Controller - Low Noise Inline HVAC Blower Can Fan for Basements, Bathrooms, Kitchens, Workshops, 8-Inch

Plugged in, switched on, 3 seconds and smoke comes out from the fan. Completely dead, so far had to pay £30 to ship it back, waste of money and time, bad experience. Got a German's made, works great. Germany-USA 1-0

Rented out a house where I had to run heat to a bedroom and bathroom that the previous owner converted from a garage. Ran duct instead of the baseboard heater that was previously installed. It was a pretty long run, about 35' of 8" ducting and a couple branching off of that. 4 total registers. Went to the orange store to buy one of these but they didn't have the 8" in stock. Said I'd have to order it online and when It comes to that, I'd rather just order it on Amazon. This thing is solid. Metal fan blade, pretty solid housing. And cheaper than the store by about $20. Probably got it faster than if I'd ordered from the store too. The housing is a little smaller than a normal metal pipe but it wasn't a major difference and was a tight fit with the tape. I supported it from the ceiling because it has a little weight to it but that's a good thing. It actually looks nice, too bad it's mostly covered by the other ducts. Love the fact that it has a speed control on it, makes it more adjustable. It's not just 3 settings, it has "off" and all the way up to high is incrementally adjustable. It pushes some serious air. Without it attached to the duct work, it seemed like it was pretty loud on high but with it attached, it's no louder than the furnace. I also got a BN-LINK Heat Mat controller because the one at the store looked old, clunky and awkward. It was also more expensive. So I got that and it works great when the furnace is on and turns off when the furnace turns off. I'm happy with the setup and the price. Tenants love it because it makes that bedroom and bathroom warm like the rest of the house. Sorry for the long post but I like to give credit for a good product and show how I ended up using it.

Good

Très bien pour propulser l'air chaud de mon poêle au sous-sol vers le rez-de-chaussée.

This thing works as advertised. I wanted to grow mushrooms and needed a flow hood. I put it together with duct tape, this fan, HEPA filter, and a plastic box. The fan was not quite powerful enough to send out a lot of air for my needs, but it does blow air as it is advertised. I should get another one for the other side to achieve my goal of blowing air through the charcoal filter.

This review is for AC Infinity RAXIAL S8, Inline Booster Duct Fan 8” with Speed Controller - Low Noise Inline HVAC Blower Can Fan for Basements, Bathrooms, Kitchens, Workshops. The fan was delivered on-time, complete, and as described by the seller. It was well-packaged in a custom box and included a user manual, 2-year warranty information, and hardware for mounting the speed controller. The cylindrical structure is sturdy and nicely finished, the plug-in power cable and speed controller are integrated and the fan runs smoothly with little vibration. The speed is continuously variable with a dial control from OFF to maximum; at highest speed it makes about as much noise as a pedestal fan….. the sound is principally from the airflow itself. The fan has steel blades and is designed to be mounted/suspended inline in an 8-inch diameter ductwork; there are no mounting brackets provided. I am using this fan, funning at medium speed, to increase ventilation in my attic with the expectation of improving the efficiency of my A/C system (also installing a reflective radiant barrier throughout); so far I am satisfied with the performance. I am using an Amazon Smart Plug with the Alexa application to run the fan on a regular routine and/or use voice commands to turn on and off remotely as needed.
