How to Build Your Own Central Vacuum How to Build Your Own Central Vacuum
Although building your own central vacuum is tiring and physical work, you can usually complete the project in less than a day. Be warned, however, that some of the equipment, although inexpensive or even free, might require some time to find. You can probably procure the fridge compressor unit from your local fridge seller, who likely has spare parts. When extracting, transporting and handling the compressor, make sure that the swilling oil remains in the container for two reasons: The oil is hazardous, and it is also necessary for your operation.
You can extract the admission advance regulation valve from almost any old engine, and you might obtain the glass syringe from your pharmacy. Finally you can buy the manometer (a low-cost item) in any ordinary automotive store.
Step 1a - If Using a Valve for Your Central Vacuum
Build a box out of the plywood. This will contain all the hazardous parts. Install the valve outside by feeding the iron wire into the box. Bolt the microswitch to the base and connect or solder the power wires to the microswitch. You do this by installing the bolt and spring and connecting it to the iron wire coming from the valve. Place two pieces of wood near the switch button and solder the whole.
Step 1b - If Using a Syringe for Your Central Vacuum
If using a syringe, make sure that the syringe is firmly attached in a vertical position. For success of the procedure, the syringe must be well-secured and should nudge only when the switch reads "On."
Step 2 - Install your Fridge Compressor
Carefully install your fridge compressor on a wooden plate. Use the rubber tubing that you found when dismantling it. Make sure that the tubing on your fridge compressor does not exceed 8 cm.
Step 3 – Start the Compressor
Start the compressor, but keep out of the way since some oil may spurt out.
Step 4 – Attach the Tube and Ball
Attach a 20-cm tube on the "out" tube. Guide the tube vertically around a wood stick, drill small holes into the ping-pong ball ball, and place it on the end of this wood stick. The holes enable the air to escape, while the ball itself acts as the oil recuperator.
Step 5 – Adjust the Tube for Your Central Vacuum
Fix the vaccum tube to the "in" tube of the compressor. Add a T-bolt to the compressor tube and feed one part of the tube into the inlet of the regulation valve. The other goes to the bag.
Step 6 – Seal Your Central Vacuum
Seal all links with silicone and tie-wraps. Leave your central vacuum to dry.
