just started to make a scale drawing (only have windows Paint for it somewhat slow)

I must correct myself i plan to use some low noise papst fans: 12dB and around 19 CFM for the bong, i have to do some preliminary tests, probably I'll have a bunch (six) of them in the upper end of a box shaped bong.
