iPower4 Inch 195 CFM Inline Duct Exhaust Fan Air Vent Booster Ventiliation Blower for Grow Tent, Attic, HVAC, Basements or Kitchens, Low Noise, Black

I used this exhaust fan to vent my xTool D1 Pro laser, as the fan that came with the enclosure wasn’t strong enough. This iPower fan works great—it’s powerful, quiet, and does an excellent job removing smoke and odors during lasering. It’s been a solid upgrade for my setup and has made a big difference in keeping the workspace clean and clear of fumes. Highly recommend it if you need a reliable exhaust fan for laser operations!

While using this and setting it up I dropping it close to 6 times from over 5’ high onto a concrete floor each time it was on and running when stoped and this thing took it like a champ, didn’t crack or break! Works great still to this day and it runs 24/7. I am happy I purchased this product and would definitely recommend anyone eles looking for this style fan to look no further this one works and will hold up!

Brought it to start my tent with the intention of upgrading it later, but this little guy has been humming along for months and not giving me a single problemWell worth the price nothing super fancy just a good quiet fan

Actually pretty impressed by this fan. It blows a lot more than oscillating fans, because it can be clipped in your tent hole perfect. It cooled my tent a bit, and it’s actually extremely quiet! Love it

Easy set up and operation, half the price of the store bought models.

After 2 or 3 weeks it started dying, making a rattling or scraping noise. Also lacks a switch so it's just plug it in and it starts going full speed right from the start, which isn't a bad thing but it's something to be aware of.

Used on engraver in garage to suck smoke out. Worked really well. Just routed dryer hose to back of fan.

These are the weakest fans I have ever purchased. I have gotten several other 195cfm intake/exhaust and these were definitely a waste of money. I was gonna use these in my smallest tent but they don't even produce enough airflow. I definitely do not recommend these fans, keep looking and any other 195cfm will give you what you need. The only reason I gave the 1 star was because they were a fan like advertised but other than that was useless for my needs.

Garbage, lasted 5 minutes then went load and started to smoke, could of burnt my house down

Broke immediately. Started making noise and stopped. Fumes after.
