Why a Cyclone Separator
A cyclone separator is essentially a bucket with a fancy lid. When connected to a vacuum source, the lid creates a cyclonic suction that collects large dust particles minimally, and the small dust particles at best. By adding one of these to a standard shop vac or dust extractor, you can collect much of the dust before it ever reaches your vac's filter. So why would you want to do this? One reason is safety. Many times, a filter will get clogged with both large and small dust particles, eventually clogging up the system. This could lead to dust leaking through the system and being expelled back into the shop air. By removing the large particles and even some of the smaller particles, your vac filters don't have to work as hard and are less likely to become clogged. At the very least, it will take a lot longer for a clog to occur.
The second reason is to save money. I never run my shop vac or dust extractors without a filter bag. Disposable filter bags wind up costing me a lot of money over time. By separating out the chips and dust BEFORE the vac, I can simply empty the bucket over and over and the fill rate on the disposable bags drops dramatically.
I'll be reviewing the following cyclone separators: The Oneida Dust Deputy, The ClearVue Mini-CV06, and Rockler's Dust Right Vortex.
