## Description

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 : desertcart.co.uk: DIY & Tools

Review: Burn out after 3 seconds - 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
Review: 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 desertcart. 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.

## Questions & Answers

**Q: Can you add a carbon filter**
A: I'm using it with a 4" carbon filter in my veg/mid  flower 2x4 tent. Airflow is pretty reasonable coming out of the end and the air is scrubbed good with a clean fresh smell. I'm here because I'm buying a second one to use as an intake fan to complete the setup. I'm only running 1 95 watt light in this tent so I don't need extreme airflow. In my 3x3 flowering tent however, I  am running the ac infinity cloudine 4" fan with the ac infinity 4" carbon filter. More lights and more smell equals more airflow needed.
These are a little bit on the louder side compared to the cloudine so if that doesn't bother you then you'll be ok. You'll need those running at full speed with the carbon filter. I run my cloudine at half speed. 
If you're looking to save some money then it will do the job but the cloudine is the one to get otherwise. 
I'll probably get another cloudine in the future for my veg tent but for now this will be ok.

**Q: Will this plug into T8 digital temp and humidity control?**
A: I use it in my tent to exhaust air out and have it in a timer, but you can def plug it into an environmental controller.

**Q: I need to run at approximately 190 to 200 cfm. Would it be quieter to run a 6 inch at high speed, or an 8 inch at low speed to achieve this flow?**
A: Go with the 8 inch which will move more air at lower speeds. Higher speed it becomes a small wind tunnel and is loud..

**Q: can this fan be used on the end of a hose connected to an engine exhaust pipe to help get the exhaust out of my garage?**
A: Usually when you are venting a car exhaust you would hook the hose directly onto the tailpipe and then vent it outside. The force of the exhaust would not need a fan. You could put this fan above that area and suck out any air that you do not want.
I have mine hooked up basically for the winter time to suck the hot air around my furnace and heat another room in the basement, and it works great.
