Shopsmith Forums

Perhaps one of you could help me with this. Engineers because of their expertise and politicians because they have extensive experience in hot air, what sucks and what doesn't.

I have a Silent Master Whole House Vacuum which is never used. It is 240V and the unit is located in the garage about 20ft from my shopsmith. I can't find out what the CFM is for the unit and the company only posts information on "water lift", or some such which is supposed to be more important than CFM

I'm considering this as a good source for extracting dust and other particles.
will this work? Do I need a Dust Deputy inline first?

If I do this without some knowledge and it gets screwed up my wife will let me know, even though she doesn't like the system and doesn't use it. Some of you will understand that thinking. I don't although I live with it.

I went out and found some replacement motors for whole home vac systems.

One motor, that seemed to be an average representative, was rated at:

Waterlift 110", CFM 102.7

You can cross multiply to get the results. If you give us the Water Lift value, I will calculate it for you.

It will be ballpark, but get you in the area.

I would definitely use a separator. I wouldn't want all the dust and debris in the vac system....

I am not real familiar with vac systems, but just picked up a Jet DC, it is rated at 1100cfm at 11" water column. So based on that and rjents #s on vacuum #s, dirt vacuums have stronger suction but less air flow volume, where a DC has a large volume of air movement at a lower suction. Maybe that is needed, the larger air volume because a machine is not as air tight as the head of a dirt vacuum against the carpeting. You do need air flow in both to move the particles to the collection site.
