Does it have the power to pull vertical ?

I’ve been happy with the HF dust collector. It has always cleared all saw dust and chips I’ve thrown at it. I built a pvc collector “manifold” to consolidate my connections….

Router box, table saw and the small fitting with the blue aerosol cap now has a vac hose attached to a oscillating spindle sander (sits in front of the post in center of pic) and can be switched to router fence.

I am tired of stepping over the hoses!!

I want to turn the “y”s around (at router) and reconfigure things so that pvc goes UP the post to the ceiling and across the ceiling to the collector. The post is just 7 feet tall and the run to the collector is 11 feet, then back down to the blower. PVC up and across to combat resistance, but probably still flex hose from jointer to the post area.

So, the duct would be smoother but longer, and have a vertical component. It’s just a 2 car garage.
I can accept it if the jointer will produce too big of chips for this.

Does anyone use the HF collector in this way? Does it have enough umph?

peace, T

A lot of ductwork runs (most of them, probably) are set up that way (not with flex, tho’). You won’t have any problems, use 4” PVC and no 90ยบ els. Use 2 45’s with a short piece of straight between them to help smooth the airflow.

Hi Tommy
My set up is not exactly as you describe,One of my HF DC units goes up a wall and the fan is mounted on the wall then the dust and chips are dropped in a container outside ,it seems to work fine.I would hate stepping over the ducting too,one of my units goes under the floor just for that reason. I would say if you try what your thinking about make sure you use long radius elbows for you duct work to make your turns.

It’s got plenty of “umph”. Pressure and volume too.
I’d stick with 4” for the vertical run to keep the velocity high, especially for the jointer.
If you can locate any long sweep 90 degree ells they are much better than two 45s.

thanks, guys.
It was specifically the HF I’m asking about. If I had a gazillion dollar unit I wouldn’t think twice about it. And I need to drywall the ceiling before going through the build, so I wanted to make sure it will have the suction before the hassle of drywalling. I hate drywalling!

Definitly will have 2 ea. 45s instead of a 90. I would like to have the blower up higher and probably will later, eventually on top of a thien baffle setup, but that is not yet.

peace, T
