Do I need both a 4" and a 2 1/4" dust collector?

[Kranzpj]

I'm maturing from using power handtools on the back porch to setting up a shop in our unfinished basement using large stationary tools, so I'm thinking about dust collection for the first time.

 

Do I need an extractor for both power hand tools (like a 2 1/4" shop vac with a separator) and an extractor for the large stationary tools (like the 3/4 HP Dust Right Wall Mount)? or can I use the 4" Dust Right with a hose reducer with power hand tools?

 

Also, since the air intake for furnace is in the basement am I going to have a issue with ambient dust getting pulled up through the intake and sent in the rest of the house? The furnace filter isn't exactly a HEPA filter.

 

Thanks

The easy way I remember it is that small tools small vac. Big tool large dust collector. The shop vac is low volume high velocity and the dust collector is high volume low velocity.

In short, the answer is yes. There is a lot of info on this forum regarding DC. Use the search feature and you will find a plethora of information.

As an aside, it's not your furnace's job to clean the air in your home. A HEPA filter can choke your furnace. Make sure you read your owners manual. The filters job is to protect the motor, which can be done with a coarser filter.

There is a mind numbing amount of dust collection information here:  www.billpentz.com/woodworking/cyclone/index.cfm

 

It seems to be a well researched page.
