I was chatting with a buddy last night about ways to free up some space in my 2 car garage workshop, and he suggested relocating my DC from the garage to the attic above. The attic space above my garage is pretty huge due to the way my house is laid out…there’s probably 20’x20’ of usable space with enough height to walk around. I put particleboard down across the trusses, so it has a fairly sturdy floor. He was thinking that I could relocate the DC up there and install a switched electrical outlet so I could turn it on and off from the garage below, then just cut a small hole through the drywall ceiling of the garage to route the piping down to the garage.

Emptying it would become a little more involved, but I think I’d be willing to deal with it in exchange for the extra space since I don’t have to do it all that frequently. My biggest concern was whether or not the DC would still function properly if it was located that much higher than all of the tools? I have one of the cheap HF 1.5hp DCs, and while I think it would probably suck up dust just fine, I’m a bit skeptical about it having enough power to suck up larger wood chips. Any thoughts?

It does not take any power to lift air to the attic. The only additional power required would be the extra effort required to lift the sawdust, which is very small. Even a 1.5hp DC could keep up (assuming it could keep up before). It sounds like a great way to reduce noise.

Since it is in a garage, you need to have a closed system with an air return. You don’t want the DC to suck air back though your water heater vent and bring carbon monoxide into the room.

I have heard that it is good to have around twice the cross section for the return air. If you have 6” pipe going up, you would want at least 8” or larger for the return air. There is no point in choking the system with back pressure for the return air.

My DC has been routed 10’ off the floor and dumps out side fore years.

The only drawback I can see is heat deterioration of the windings and such on the motor. Attics get awfully darned hot.

Wow, thanks for the info, sounds like it’s worth looking into.
