I switched from using my Dust Deputy with my Shop Vac to using it with a re-purposed and rebuilt whole house central vacuum unit given to me by a neighbor who was major renovating his house. I installed both this central vacuum unit and the Dust Deputy in the attic above my shop with vacuum inlet ports in my shop, the attic, and one outside for vacuuming my cars and trucks.
I have a small shop, so the high dust producers that generate the larger wood saw dust and chips don't get hooked to this vacuum. The Unisaw base just collects the sawdust from it until I shovel it out and I do my planning using my DeWalt 735 with the accessory dust hose/drum cover. My scroll saws, drill presses, Sand Flea type sander and my hand sanders all get connected to this central vacuum system one at a time as I need to use them. I also vacuum the shop floor with it. I started with a 5 gal. plastic bucket under the Dust Deputy, like I had when it was hooked to the Shop Vac. The Shop Vac never imploded the bucket, but the cental vac imploded it within the first minute or so of use. I then stacked three buckets of the plastic buckets together, to triple the wall thickness and get the reinforced top areas of the buckets to cover the full length of the top bucket. This solved the problem of imploding buckets, but I have since replaced these buckets with a steel 20 gallon grease barrel and a plywood top made from 2 layers of 3/4 cabinet birch plywood. I used the O ring seals from two of the 5 gallon bucket lids to seal this wood top to the metal barrel.
This Dust Deputy and central vacuum combination has been in use in my shop for about 1 1/2 years now and I'm quite pleased with how well it's working out for me. I'm still amazed with how well the Dust Deputy separates out the sawdust and debris. Almost nothing visible ever seems to reach the central vacuum container and filter. I have the exhaust vented through the roof soffit, so anything micro fine that might make it through this system gets vented outside, and not back into my shop. I no longer have a Shop Vac in the shop at all as this attic vacuum system does everything that I would need a Shop vac for without consuming any shop space at all. This isn't a perfect solution for a wood shop dust collector, but it does well for my small shop.
