I'm assuming this works, just playing with an idea. Can you have multiple airlock s dumping into a common pipe for transferring?
We currently have a 20hp Murphy Rodgers baghouse, and a separate 7½hp Oneida on the router. I'm thinking about getting rid of the baghouse, and moving the cyclone into a lean-to on the side of the shop, along with three more of those dust collectors. Line them all up, airlock into a common pipe, blow it into a trailer.
We're a very small shop, in a good sized building. We have a lot of equipment for the number of workers. It's tough to justify the bigger dust collector running when it's just a dude standing at a cut off saw, and nobody else needs DC are that time. I've got three trunks that come together and would be super easy to modify them so they go out the wall separately. The pipes could easily go out between studs, the current opening in the wall for dirty air going out, and clean air coming back would be more than adequate for just a return air from the lean-to
I priced out a new system, I don't have $100k to throw at this problem, and it wouldn't cure the electrical draw problem.
Thoughts?
