Hey guys,
has anyone looked into a better fan-blower set up for running 2X riffle trays for a dryblower instead of running 2X leaf blowers?
ie a single unit either a petrol motor option or 240v run of genset jobbie cheers guys in advance. :)
 
there is a pic somewhere out on the interweb thingy that shows a 5 or 6 bank keene dryblower in Sudan.
each one is running a bouncy castle type blower fan.
I have played with them as dryblower fans but scraping and detecting intervened and that project is on hold.
 
I made a dryblower years ago, that was also a gem shaker. It works off bellows, but I think I would have a hard time finding the plans for it. If you happen to live local, you are welcome to take a look at it.

I have no idea about dry blowers. Do ya need pressure or volume or both? First thing that came to my mind was a jumping castle fan. Plenty of sizes and prices available on ebay.
