That der' 6.5hp shop vac

[tp4tissue]

haz ne one tried the 6.5 hp ridgid shop vac from home depot..  or any 6.5hp vac



Tp4 owns the 3.5hp one,  kinda wimpy..  is 6.5 much better ? 

[tp4tissue]

my concern is,  since the filter is the same size..  it'd probably get clogged at roughly the same rate no? even with more power..

[tp4tissue]

Also.. what doesn't make sense to me is.. how are they even getting 6hp from the wall..

wouldn't that require something around 50 amps.. ?

Are they lying to us..

[tp4tissue]

with 15 amps 120v.. shouldn't the maximum be around 2 horse power assuming an 80% efficiency rating...

Yes, yes, yes, and yes. Some filters have more pleats giving them more surface filtering area while being the same size. They cheat with the specs by quoting peak HP not continuous HP. In a shop vac most of the particles fall in the container without clogging the filter. Only the fine dust and lint make it to the filter. Regardless, you will have to occasionally  clean the filter and eventually replace it, so try to get a vac that can be easily opened to clean.

The big Ridgid has good sucking power, especially when using the big hose. I own several of them as well as 3 much more expensive ones and for power, the Ridgid is the best. You could do a lot worse

Gah...

I knew it werez marketing trickery..

That probably means, my current vac is only 1 horsepower, probably even less.. 


peak horsepower would be inrush current which is ~4-10x greater than continuous..

I feelz so violated by the industry..

Yep. A more consistent way to compare is just to go by the amperage.

Power is just one of many things to consider. Some are just more efficient at picking up stuff. Some are better for big chunks, the Ridgid for one, while others actually have a stronger vacuum but not the volume.

 A flexible hose is more  comfortable to use . Some have auto starts that turn on when a tool plugged in is turned on.

Noise can be a concern too. Check decibel rating.  Many vacs offer different filters from standard to hepa. How clean does the exhausted air need to be?

I am picking up some concrete dust, and drywall dust, some glue dust

Ordered some replacement generic filters off ebay , it's suppose to be a step up from the original stock filter which is only 1 layer.. the generic claims to be 3 layers, and fits my wimpy 1 horsepower ridgid.


The hepa 5 layer version is $30  vs $15 for the 3 layer..

Not sure I need hepa right now,  since i'm wearing a mask anyway..


I ended up redoing some of the drywall..


This basement thing has become kind of a pandora's box..   just stuff upon stuff to do.. hahahahaha..



I'm even considering tiles now... because if i wanted to get tiles later,  I'd have to do grinding ALL OVER..


So maybe one shot this.. hahahaha.
