Just as every shop is different, the appropriate dust collection solution for every shop is going to be different. You'll need to consider the size of your shop, the number and types of tools you want to connect to the system and, of course, your budget.
For some handheld power tools, a shop vacuum will be an adequate or even ideal dust collector. But most larger woodworking machines, such as a table saw, jointer or planer, will require a stronger dust collector with larger-diameter hoses or ductwork.
Basement and one-car garage sized shops
The Dust Right® Wall Mount Dust Collector is an excellent choice for a small woodworking operation where an affordable solution is the goal. With 650 cubic feet per minute (cfm) of suction capacity, this compact dust collector handles serious shop messes without cluttering up your workspace. It mounts in seconds with simple included brackets. For even more versatility, order a few extra brackets and install them in strategic locations around your shop. Then use the comfortable foam grip handle to move the unit to wherever you happen to need it. With a host of attachments and fittings available, the Dust Right system can give you complete dust collection in a compact package with an affordable price.
If you want central dust collection in a small shop, dust collectors in the 1,100-1,200 cfm range offer an economical solution. Good system design will go along way in making dust collectors in this class perform well in a central dust collection system. Of course, many of these dust collectors are portable and can be wheeled from machine to machine. The quick-release fittings in the Dust Right line make connecting to different machines fast and easy.
Two-car garage sized shops
If your shop occupies a space about as big as a two-car garage or you have tools with very high cfm requirements, then moving up to a powerful 3-hp dust collector is probably your best choice. Dust collectors in this class typically pull upwards of 2,200 cfm and are rated at 10+ inches of static pressure. With good system design, that's enough force to pull debris through the longer lengths of ductwork necessary in a large home shop.
Small professional shops
If your shop is bigger that a two-car garage or you frequently have two or more people using machinery at the same time, you may need more than one of the dust collectors mentioned above to do an adequate job. Or you may just need a larger dust collector. Moving up to a 5-hp dust collector will typically get you a whopping 4,500+ cfm to keep bulky shavings moving along even long runs of amply-sized ductwork. Along with the increase in power, these production-oriented units typically incorporate larger collection bags to minimize time spent making room for more dust.
