Make A Carrier
The carrier is made of three pieces of wood and holds the reservoirs in two ways. The top and bottom pieces are 8.5" wide and 10.5" long. The latter of these measurements is taken from the distance between the two PVC caps on the system. This holds the reservoirs in place horizontally.
The third piece of wood (the middle rail) for the carrier is 3.5" x 6.5". The critical measurement is 3.5" because it is slightly less than the diameter of the 3” PVC reservoirs. This is how the vacuum reservoirs are held in place vertically.
| Parts used in this section: |
Tools Required: |
3/4" Lumber or plywood
Wood screws- #8 x 1.5" (4)
Handle
|
Screws - #4 x 1.25" (2)
Screws - #4 x 5/8" (2)
|
Table saw
Screw driver
5/8" Drill bit |
- Cut two pieces of 3/4" thick wood to 8.5" wide and whatever the length is between your reservoir caps.
- Make the middle rail with a piece of wood that is 3.5" wide by 6.5" long.
- Assemble the middle rail to the bottom piece of the carrier using two woods screws.
- Place the reservoirs units onto the carrier as shown.
- Drill a 5/8" diameter hole through the top carrier board. It should be centered on the width and approximately 1" from the edge. Now attach the carrier top using two wood screws. Do not over tighten these screws. You’ll only need enough pressure to hold the unit together and to keep the reservoirs from sliding inside the carrier.
- Attach a handle to the carrier as shown. I bought the handle for this unit at the local hardware store for $3.

Attach the Vacuum Generator
Using two #4 wood screws (1 ¼” long) attach the venturi to the top of the carrier as shown. Be sure the body of the Mac valve is snug against the edge of the carrier. This will remove the force from the small screws that hold the venturi in place when the quick connector from your air compressor is attached.
Set up the Vacuum Controller
The vacuum controller regulates the pressure inside the system and turns the vacuum device on and off as needed. These are adjustable up to 28" of Hg. The vacuum controller is mounted to the system carrier and connected via vacuum tube.
Wrap the threads of the vacuum controller with thread sealing tape and attach a 1/8" NPT barbed fitting onto the unit. Do not over-tighten the fitting. The maximum torque for the plastic body of the vacuum controller is 4 inch lbs. Attach a piece of tubing to the barbed side of the fitting and insert the tubing through the hole in the carrier so that the tubing is pushed forward toward the manifold. Use two #4 by 5/8" screws to attach the vacuum controller to the carrier. Do not over tighten these screws.
