This is certainly a “repurposing the bones after said horse is dead” reply, but when searching for info online one comes across old threads with useful replies – so why not?
My plan is to install a vacuum dust collector system in my shop. I bought a CamVac CGV336 55 litre, 2000W which I intend to connect to a duct system in my shop. It filters to 0.5 microns.
I bought a huge dust shroud thingy (CVA400-50-123) I intend to mount / clamp to my workbench when I’m working with dusty tasks. Should do the trick. The dust collector is rather noisy, but I found a guide to make sound dampers for the exhaust – should be a good solution even if I have to use ear protection somehow. My noise cancelling headphones might be ideal for this, as I can listen to podcasts, music, radio – or nothing.
I have a regular “chip collector” from back when I thought woodworking meant machines everywhere, but it does not handle dust. The Camvac is a completely different beast! Block the hose on the chip collector, and nothing really happens – the filter bag limps over after a while.
Do the same thing with the Camvac, and it sucks itself across the floor! Scary thing, really! 🙂
If I put the chip collector on my Record Power BS 400, it removes a good amount of sawdust – but a lot of sawdust ends up around the base of the saw, on and under the table and a lot of other places. Put the Camvac on it, and the problem is gone! The extra dust hose connected directly beneath the table works very well with a vacuum dust collector. Not so with a chip collector.
Another approach for dust filtration, cheap and DIY: A big box fan (or any fan capable of moving a good amount of air) and filter cartridges for ventilation systems. Matthias Wandel has videos on the subject.
