Intro: PVC Garage Central Vacuum System
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"
I decided to use 1 ½ inch pipe for the system. The 1 ½ inch pipe fits best with the hose that came with my wet/dry vacuum. It will also connect right up to my dust separator.
- 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
I picked three different areas in my garage. Front wall by the garage door, middle center, and back wall by my workbench. Green star in each picture shows the location.
Step 3: Hanging the Pipe
I started by cutting the pipe hangers down a bit. This will allow the pipe to hang down about 3 inches from the ceiling.
Step 4: Cut to Size
Now that a couple of the hangers are up, it’s time to cut the pipe to size. After you cut the pipe, make sure to clean the ends up. I took the inside edge down. That way nothing would get caught when in use. Once the pipe is cut to size hang it up on the wall. As of right now I am not gluing any of the ends up, saving that for later.
Step 5: Now for the Hard Part. Kind Of.
I have a large support beam that divides my garage. So the connection layout was a bit tricky. I also had the middle section and dust separator to connect up. Blue tape was a reference line for my mock up.
Step 6: Last Bit of Pipe.
The last bit of pipe and the shortest was for the front garage connection. In the picture you can see that I used the end caps as a shut off. This will allow me to shut off the ends and move the hose around. “see yellow box”
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.
