Question: is the blade reversible?
Document: it was on my door step the next day i ordered two. one was ready to go i had to put the blade on the other. (it was easy no big deal at all one screw) both worked fine but they do NOT move 240cfm but they move enough air to cool my cool tube reflector. they are loud alone but when the ducting is hooked up they are quiet. i wish i had ordered 3 instead of 2
wouldn't you know it....as soon as it got warm out it broke. P.O.S. not happy at all. i guess you get what you pay for
works great but its very loud fan made well could be made not as loud metal made from is nice and thick so long life moter not sure hope it last long time
venting a 50 square foot tent and it clearly creates negative pressure (doors pull in). However, it is crazy loud! It's not so loud that your neighbors will freak but it can be heard from another room with the door closed. I probably overdid it a bit so maybe if you have a similar tent get something smaller?
this is great for boosting airflow to those rooms furthest away from the furnace and works well, well worth the money.
this fan let me keep a 400 watt HPS light less than 12 inches from the canopy of my crops. I put one in front of an AC vent to bring cool air into the closet near my light then I sat a 2nd fan on the shelf in the top of the closet. I draped down some Ven tech ducting and used it to pull the hot air out of the closet. I had about 4 feet of ducting on each side of the fan and no problem it worked great.
the fan work better then the one i got from the store and i was thinking about geting one more
not enough air
needed to move air through tent from outside,not noisey at all,would purchase again if needed.not bad for under 30 bucks.
its fairly noisy and doesn't move much air. Pulling thru a carbon filter and exhausting thru 6' of duct, there is a very slight flow.
Answer: yes
