Thanks so much for posting this! |
I am taking it a step further and running another pipe right into the apex stopped of at the end,with holes drilled into the top with another fan about halfway along with another set of electrics but using same battery.
Iwill feed this into the existing downpipe,hopefully will pick up all available air.
