Step by Step Guide

The following guide will help you assemble a vacuum pump with an air compressor.

Just follow these simple steps and even if you’re a beginner, you’ll end up with a piece of amazing equipment that is reliable and durable.

Step 1: Safety First

Better safe than sorry, right? Before you start this or any other project that involves stuff like air compressors, you need to make sure you are taking proper steps in protecting yourself.

So, in that way, even if you make a mistake or mess something up, it won’t affect you or any of your body parts in any way.

So, Before you go all in and start with your vacuum pump project, one thing you should do is to get ahold of your safety tools and put them on!

Your safety tools are the only thing that will protect you in case you face any mishap during the project, so don’t even think about ignoring them even once!

Step 2: Understand your Tool

Once you have done all the safety steps, it’s time to come down to the real work. We will first start with understanding your air compressor properly.

What you have to do is to read your compressors manufacturer’s instructions carefully or search them up online; this is an important step because your will be opening up your compressor, so you have to be sure that you know what you are doing.

You can also read the user’s manual for additional help and assistance. Another thing is that some air compressors are strong, and you will need more force to open them up.

Don’t panic if you can’t open them up; you just need a little more help!

Step 3: Remove the Compressor’s Cap

After you have completely understood your compressor, it is now time to open your compressor. Once you remove the cap of your compressor, you will see the pump.

Keep in mind that your focal goal here is to find the cylinder, which is mostly located under the pump. What you will need to do is to push or pull your pump to expose your cylinder.

Step 4: Attach the Vacuum Hose

Once you have successfully located your cylinder, it is now time to attach your vacuum hose to the PVC hose, but before you do that, you first need to work a little on your vacuum hose.

Take the fittings and the measurement of your vacuum hose to make everything easier. Then seal the area surrounding the intake holes and attach the bard to the epoxy.

Once you do this step, set it aside and let it dry for at least 24 hours; keep checking it every two hours or so to see if it’s drying.

Step 5: Attach PVC & Vacuum Hose

After the bard and epoxy have been attached perfectly and dried too. It is then time to bring the PVC hose into action. I would suggest you get a PVC hose that is ¼ inch thick.

Once you have the PVC hose in your hand, attach it with the vacuum hose you previously worked on, make sure you clamp both of them with the help of a barb.

You can also use a hose clamp to attach them together if you are too worried.

Otherwise, the bard will do just fine. Once you are sure that the vacuum hose and the PVC hose are attached firmly together with the barb or the hose clamp, let it sit.

Step 6: Create a Hole

You are now too close to successfully making your own vacuum pump with an air compressor. Just a few more steps, and you will be all good to go!

Now all you have to do is to work with the case; what you have to do now is to make a hose in the case so that you can easily pass your vacuum hose through the hole.

You can easily create this hole with the help of nippers in just a few minutes. Make sure you make a hole that is not too small for the vacuum hose or too big for it. (Note: Place the start of the vacuum hose on the case and do all the markings that you need and then start cutting for the hole for the perfect measurements)

Step 7: Reassemble!

Once you have successfully passed the vacuum hose through the hole you made in the case, you are all good to go!

Congratulations, you have successfully made a vacuum pump with an air compressor, all by yourself! Now you don’t even have to think about spending money on vacuum pumps anymore!
