Yay goodies! Been waiting forever to finally order this fan for the veg closet.
In case you don't know, I love hyperfans. They kick so much ass. I get a TON of push back when I suggest them though. People will gladly drop a grand on a light but balk at $250 for a fan and temperature speed controller.
These fans move more air per watt than anything else. Everyone is always trying to squeeze every last photon out of their lights and every last gram from their plants, why not demand the same performance from your environmental setup? There's no reason to waste energy your going to pay for it at some point.
Here's some of the documentation to further illustrate why these things rock. Keep in mind it is provided by the manufacturer but the claims seem accurate to the 8in fan I've had running continually for 2 years now. It powers two 4x4 tents.
This shows how fast they pay off the cost difference to cheap fans.
These are fan curves that show the actual performance of the fan once it's loaded up with a carbon filter. They only provide numbers for their line but it shows how every fan reacts to being loaded up. Your not getting the airflow numbers listed on the box, hate to break your heart but your 6in centrifugal isn't moving 300 CFM with a filter on it, or even duct really.
Here's a little bit more info on why the motor they use is better than anything else on the market.
I'm not paid by hyperfan, I just can't stand watching people waste energy simply because they're cheap and Ill informed. The average household uses about 30kw/h per day, a lot of grows use that much, 2x 1000 watt hoods on a flower schedule is 24kw/h per day, almost as much as an entire household uses, just for two lights. Just think.
