Toolazy Quiet 8" Inline Duct Fan 831 CFM Ventilation Exhaust Fan EC Motor and External Electronic 10-speed Controller for Heating Cooling Booster, Grow Tents, Hydroponics

I am totally impressed you can regulate the flow with the remote I will say increase your suction slowly this is a powerful unit. I have a large bed size hi powered laser engraver and it clears every bit of smoke and smell

Shipped on time, unit is mostly all plastic, operates as described, you get what you pay for.I use it for a a small fiber laser and at high speed it pulls the fumes just fine.

Good construction of unit. No complaints

Loud

Great product works like it says

These fans are awesome. They have a little variable speed controller on them and the fan returns to the same speed when you remove/restore power. These fans move a TON of air wide open, but they are kind of loud wide open.We’ve always had poor air circulation in our upstairs bedrooms and several years ago I added a squirrel cage type “booster fan” which seemed to help. I removed those old booster fans and installed these.I set them to about 60% speed because that seemed to be the sweet spot for noise. My flow meter in my upstairs bedroom went from 70ft/min before to 270ft/min. It was over 400ft/min when the fan was wide open (although very loud)I’m really happy with these fans. They’re set to come on and off with the blower fan on my furnace after I added a couple relays to control them.They’ve only been installed a week. I’ll modify my review if anything changes.

Super powerful and quiet

Plug and play. Great value for the money. Fan works great. I use the Toolazy fan to inject air into my indoor grow tent, so it runs 24 hours a day non stop. Air flow is steady with limited noise level as advertised. Multiple speed settings give you multiple optionns. Good buy for your indoor garden.
