Digital Mixed Flow Fan 6" 315 CFM, Energy Efficient Technology, Quiet Operation, Lightweight, Includes The Hyper Fan Speed Controller - ETL Listed

Awesome fan!!!!! Didn't buy it for a grow room. Bought it to circulate air in my apartment with window AC and baseboard heat. It's pictured with a i power 8 inch activated carbon filter for better air quality as we have black mold and bad smells from time to time. Only had the fan for 2 days running 24-7. Speed controller at 35 to 50%. The cord for the speed is 16ft which is plenty for my use. No scratches dings or dents.No missing parts or bends in the mounting plate. No bent wires or broken connectors or loose screws. I've read tons of reviews on this fan and I'm very pleased with it. The only thing that caught me off guard was the two year warranty which I read in another review it was a typo when they printed all the material on the box and in it. Got it in 2 days shipping wise. It moves a ton of air. Will not stay like the pictures if my ducting ever gets here. I have it on a push button outlet that's rated 5 amps for easy on/off ability. Added a short video my mic isn't that great but you can sort of hear it ramping up and down. Might sound like it hums but it doesn't. If I ever get a house and it doesn't have central air I'll probably get another 8 or maybe a 10 inch fan from Hyper Fan to do the same thing! If you haven't seen the you tube videos also the wattage is 100 watts at 100% 50 watts at 50% and 10 watts at 35% which is incredible for the air it moves. 10$ extra a month to run it all out 24-7 isn't a bad price point including it has compatible speed controller and 5 year warranty you would have to be crazy not to spend extra money on this fan unless it's going to be in an area over 110 degrees.

I bought this product a second time after the first one died when a huge storm went through our area and poured record-breaking amount of rain and some of it went through the roof vent (blown by crosswinds), dripped into the interior compartment and fried the circuit board. I had installed the first one in the attic above my friend's nail salon 18 months earlier and it worked wonderfully. Small, compact yet powerful enough to vent a 6 chair nail salon with barely any detectable sound when it was turned on. Even though the price had gone up 25% compared to the first purchase, it was still a good price/deal! I was also glad to see that the second one had a slight but notably critical improvement in design to prevent water entry from the top down. It would have definitely prevented the frying of the previous fan!

Quality product. Update: Upping to 5 stars after a solid 12 months of use. Reliable, quiet (after working thru flow issues, see below), adjustable speed, and powerful! Original comment: Only a week in, so will update later if reliability problems come up. Using for distributing wood stove heat through ducts to other parts of the house. Seems to be on the loud side however - I am finding with this much air flow (10 inch is over 1000cfm), little things become big noises and so far it's not the fan's fault. E.g. The metal registers on the two 4"x12" registers for intake over the stove were vibrating at higher speeds. The vibration sounded like a distant tornado siren - not pleasant, and hard to pinpoint. Until removing the registers, I had to consider the fan as the source, but after changing the registers the siren sound is gone, so not the fan's fault. Now I am working on what sounds like a jet going overhead downstream of the fan (all insulated flex ducting). I'm thinking it may be due to back pressure at the fan, which goes directly into a 10-8-6 tin wye. Will update as I install more downstream ducts as this should reduce the back pressure. If I get this sounding better it will be a 5 star review. Update: indeed another downstrem outlet helps to reduce jet sound.. proof, when I close register rumble is louder.

glad i spent the extra money this fan is great and if it lasts will pay for itself in power savings over the others! its light for its size and pretty compact really has some great power! fan draws maybe 1amp speed control is a is a nice feature, i have it hooked up to a 1000w cooltube hood w/mh bulb setup in a 5x5x6.5' tent light is about 24" away from my non fruiting tomatoes temp is holding steady at 77 deg running at 80% or so humidity well its november but its holding steady at 50-55%. its quite enough i mean you know its going but its alot quieter than say a air conditioner. right now i dont have a carbon filter hooked up but it will be even quieter than it is now im sure! hope this review helps folks who are trying to decide if its woth the extra coin!
