For the longest time I wanted a central vacuum system in my garage. I build and tinker a lot in my garage. The one thing I hate is dragging the vacuum hose all over. So I finally decided to take the time and run some pipe in my garage.
Air and wood particles moving through the dust collection system quickly build up static electricity charges in any non-conductive hose or piping (hose or piping not made of metal). When this static buildup discharges, it could lightly shock the operator or even ignite the flammable wood dust particles inside the piping. If the sawdust burns fast enough, you have an explosion.
If you have concerns about static charge, please see last image for more info.
Step 1: What You Need. "Parts"
- Wye Fitting - ABS
- 90-degree Elbow long sweep - ABS
- Coupling fitting - ABS
- End caps - PVC
- 10’ sections - PVC
- Pipe hanger
- 2" x 2" flexible pipe coupling. Used to connect the vacuum hose to the PVC. Also not shown in picture.
Yes I am using both ABS and PVC… The ABS fittings were on clearance at the Hardware store. The wye fittings will work better than a T fitting. The Wye fittings will allow you to direct the dust/dirt toward the vacuum. The Elbows are long sweep so the dust/dirt does not have to make such a hard turn.
Step 2: Choosing Your Connection Location
Step 3: Hanging the Pipe
Step 4: Cut to Size
Step 5: Now for the Hard Part. Kind Of.
Step 6: Last Bit of Pipe.
Step 7: Testing
Now it is time to test. I removed one of the caps from one of the ends and connect up the hose with the flexible coupling. One nice thing is my wet/dry vacuum has a remote switch. There was a bit of suction lost, but not that much. It still does what I need it to do.
Step 8: Static
