Fan & filter size to tent?

[brownredroost]

For some reason I’m having a difficult time figuring out the right size fan and filter for a 4 by 4 tent.
I’ve read and read and read and it’s all running together with all the different numbers.
I pretty much decided on a Hyper Fan. Which of the Hyper Fans do I need for a 4 by 4 tent?
I’ve read it’s better to go bigger than you need then I read it isn’t.
Also what size filter for the fan?
I read Phresh filters are good, so which Phresh filter would I need for the Hyper Fan?
Also the function of the set up will be use as a scrubber.

Thank you

Hyperfan/phresh do a good job of making their air flow numbers available for review. One of the only company's that I have found any data from on fan filter combos. This shows the actual airflow of the fan and filter combo. It's a great illustration of just how much a filter reduces a fans airflow.

So this shows a 6*16 would provide a little over 1.2 air changes per min. @≈135cfm/112cf

A 6*39 pushes you closer to 1.8 air changes per minute at almost 200cfm/112cf
Assuming you have a 7ft tall tent.

The amount of heat in your tent and your ambient air temps outside the tent will determine how much airflow you actually need.

Check out just4growers on YouTube. He has all the info you need on fans and how to calculate the correct cfm for your rent. It help me in my rooms tremendously...
