So I have a ridgid 6 hp 14 gal shop vac with dust deputy that I am pleased with. My long term goal was to mount the shop vac and dust deputy on the wall or in an open shelf. Has anyone ever used 20-30 ft of shop vac hose? Would the length cut down on the suction power? Thanks

Hi Andrew I have the same vacuum and I use a 20 foot hose coming form a dust deputy and it doesn’t lose any suction as far as I can tell. I also have an outdoor lighting remote switch that makes it so I can turn it on anywhere in my garage. Go ahead it should work fine

I have a 20 ft hose bought from HD it works great no loss in suction, but a lot less aggravation over tugging vac and separator around the basement between tools . Check their website. I think I got 2 for $25 each with free shipping. Same quality as short hose that came with wet/dry vac.

Yep… I have the same setup with a long hose. Works fine.

Shop vacs provide a large static head (pressure drop measured in inches of water) and can pull heavy particles. They do not, however, rapidly move a large volume of air (CFM).

As long as the long run doesn’t have leaks, it won’t have much affect on the static head.

The problem with long runs occurs with high CFM machines (dust collectors) and is related to the friction between the fast moving air and the pipe walls. The longer the wall, the more the friction, and the more the air slows down, decreasing the CFM.
