Double Blowbox

A Blowbox prototype featuring double blowers, single heat exchanger. I did this to see if slightly less-cool air in much greater volume would provide as good or better personal cooling as my regular single blower, multiple heat exchanger Blowbox.

In my opinion, the results do not justify the added complexity and expense, but with lower back pressure and twice the blowers, it puts out tons of air – albeit 20 degrees warmer than a regular Blowbox.

UPDATE: After extensive testing I’ve come to the conclusion that this is an effective cooling machine that puts out tons of air but without multiple heat exchangers, it’s just not a Frankencooler.

Stay tuned for the real thing –
