Picked up a smaller portable dust collector (Shop fox 1727) to use in my garage. I don’t plan on plumbing the whole garage, just hooking the dust collector up to whatever I’m using at the moment. The biggest port on any of my tools is 2.5”, the inlet on the dust colllector is 4”. Should I run 4” hose with reducers or should I reduce the hose size at the dust collector and run a smaller hose? I’m assuming 4” necked down at the tool would be the better option but I wanted to check to be certain. Thanks!

I think you’re right—run the 4” hose and reduce it down at the tool rather than reducing the size of the hose at the DC. I’m certainly no expert, but I think static pressure and air velocity are key considerations to successful dust and chip clearing.

Yep. 4” hose right up to the machine and then reduce. You might be able to add 4” ports onto some of your tools depending on what they are.

Thanks, do you folks have a particular 4” hose you recommend?
