iPower4 Inch 230 CFM Inline Fan Circulation Vent Blower, Air Carbon Filter, 8 Feet Ducting for Grow Tent Ventilation, Black

Works great, no problems

Quiet, long cord. Mounting holes are not far enough apart. Screws are tough to get to. Has twist lock to separate halves, it works to easily with flex tube. Had to duct tape to keep from twisting apart on its own. Works well for my purposes, venting laser engraver. Have cheap bathroom fan over laser engraver then about 25' of 4" duct, this fan, and about 8' of 4" duct to outside. Works.

This system is very simple to set up and very quiet (which was a concern when ordering) I can barely hear it run at all. Still a bit of odor escapes but I'd say it depends on your crops. Well worth the money!

A few things to note. It is NOT a fan and filter to suspend in a grow tent. The fan and filter do not connect unless you purchase an extra part to seal them. As soon as I thought I had the fan and filter on the provide suspension ropes, it came apart and fell on a plant. Super cheap design and just a bad choice.

Works as described

It works but not the best. The fan is not as powerful as I'd hoped for. Will definately be upgrading soon.

I am using this fan with my lazer cutter and it works great. It isn't nearly as loud as I expected but its not really quiet either. I'm not bothered by it running with me sitting next to it while it runs. Its not like you have to talk over it or anything, its not that loud. It does the job clearing the smoke and smell out quick. I have my machine next to the window where its vented so it doesn't need to travel to far either. So far so good. It seems to be good quality and I recommend.

Great product and great value. Pretty quit and worked perfectly. Highly recommend this product.

Everything in there to get you up and rolling to start scrubbing the air from orders and keeping your grow space cool with fresh air, bring in the fresh air with needed CO2!It’s a 4” so Not the most powerful, don’t buy thinking you’re going to scrub and cool a big room down with HPS lights. This little beauty is meant for smaller size grow tents and spaces, I would not go more than a 3 x 3 or a 4 x 4 grow tent for a maximum size. You always want max air exchange for your plants and lots of air exchange bringing in more CO2, intern, giving you better growth indoors.Would highly recommend, easy to clean and maintain as well

I bought this van to exhaust hot air from my 10 x 8 greenhouse. It has been fairly warm lately and this little fan does a good job. I've been using it for many hours now and it has performed flawlessly. I would recommend this fan to anyone who needs a fan for a small place.
