There are many reasons why you might want to make your own vacuum pump. Maybe you need to evacuate a system for repairs, or maybe you’re just curious about how they work. Whichever the case may be, making your own vacuum pump is a relatively easy process that can be done with an air compressor and a few simple tools.
In this informative article I’ll show you how to do it. In the end, I will also give you some tips on optimizing the performance of your vacuum pump. So, whether you’re new to DIY or a seasoned pro, follow along and learn how to make a vacuum pump with an air compressor.
Ultimate Guide: How to make a vacuum pump with an air compressor
- Mask, hand gloves, and eyes protector
- Braided PVC hose pipe of ¼
- ¼ inches hose barb
- Steel-filled epoxy
- Hose clamp for extra safety
Step 1: Know your air compressor
Air compressors and their parts can be dangerous if not used correctly. Make sure you know the function of each part.
The manufacturer’s instructions are the best information source to understand how it works. Learn about each part of what you’re dealing with and know their functions so that when something goes wrong or doesn’t feel right, you’ll have an idea of where things are going wrong.
Step 2: Open the case
The majority of air pump casing can be opened by pinching the end cap. Then you have to unscrew the end cap to pull it off. Once you open the case, now you can see the main components, including the piston pump, motor, and a couple of gears.
Note: The important thing here is to make sure that you put them back together in the right place when you take apart the parts.
Step 3: Locate the air intake
The air intake is the main starting point for your vacuum pump. The exact air intake location can be determined by first locating the pump or motor assembly on components and pulling it up or pushing it to expose the cylinder. The air intake enters the cylinder before being conveyed through an air hose.
Step 4: Attach the vacuum hose
You need to attach the vacuum hose to the intake. You can simply tape it on to seal, but a better way is to use steel epoxy. Make sure the hose is firmly attached to make a tight seal.
If it is not, there may be some leaking which will decrease the efficiency. Now attach the barb after sealing the intake holes, then leave the join alone for a day to hold the vacuum hose securely.
Step 5: Attach PVC hose with barb
Attach the hose to the 1/4 PVC pipe with a hose clamp. I’m simply utilizing a hose clamp for safety. If you’re confident that it is correctly put in place, you don’t need to use this.
However, as per my own experience, I advise you to utilize a hose clamp since it will hold it firmly and prevent any unexpected incident.
Step 6: Create a hole in the case
The next thing you need to do is make a small hole in the case. This will let air flow through without getting blocked by anything else, so you must make this part carefully and precisely using either nippers or pliers (whatever works best).
Step 7: Reassemble the case
After completing the above steps, you need to put the case back together. Follow the manufacturer’s instructions for putting pieces of the casing back together. After putting the case back together, test it out to see if it works.
Note: Before putting it together, make sure you don’t have leftover pieces of debris anywhere.
Step 8: Ready to go
Congratulation, you have successfully converted the air compressor into a vacuum pump. Now your vacuum pump is ready for use.

Safety tips to keep in mind while making a vacuum pump
Benefits of using air compressor as a pump
Many people don’t realize that an air compressor can be used as a vacuum pump. There are many benefits of using an air compressor as a vacuum pump. The biggest reason is that they’re fairly inexpensive.
There are different sized and capacity life air compressors that are suitable for different applications. Smaller ones are perfect for low flow to medium usage, while larger air compressors can pump a lot of air and are suitable for high-pressure pumps.
The following are some benefits of using an air compressor as a vacuum pump:
Disadvantages of using air compressor as a vacuum pump.
While there are many benefits of converting an air compressor into a vacuum pump, it is also important to know some limitations and disadvantages.
First, since it is an air compressor that you are using as a vacuum pump, it is important to remember that you cannot get a higher vacuum than the level of pressure in your air compressor.
Typically, a commercial and industrial grade air compressor for a vacuum pump can produce a vacuum as low as 25 psi (which is better than any other household appliance).
However, this will only provide you with a very mild vacuum. It will not be effective when pulling off large volumes of air.
Types of vacuum pumps
- Rotary vane vacuum pumps
The rotary vane vacuum pump is most often used in refrigeration and air conditioning. The rotary vane vacuum pump is a positive displacement pump that uses vanes to seal on both sides of the pumping chamber. The rotary action causes pumping as each vane passes through the compression or discharge areas.
- Diaphragm vacuum pumps
Diaphragm vacuum pumps are very similar to rotary vane pumps. They also use a vane system to create the pumping action. However, the diaphragm pump uses a flexible membrane as one of its vanes.
- Turbomolecular vacuum pumps
The turbomolecular pump is a special class of vacuum pumps that works by hitting gas molecules with the solid surface of blades, causing them to move one way or another.
What is the difference between an air compressor and a vacuum pump?
There are some basic differences between an air compressor and a vacuum pump.
- An air compressor converts the compressed air into a high-pressure stream. The vacuum pump does not have the capability to create a high-pressure stream. It can only create a low-pressure stream.
- Air compressors only transport gas, whereas a vacuum pump can transport both gas and liquid.
- The vacuum pump is very useful in many fields. It is used to suck up dirt, debris, and liquid. It is very useful for cleaning the carpets and curtains.
FAQs about how to make a vacuum pump with an air compressor
How does a vacuum pump work?
A vacuum pump works by taking compressed air into the hose. The hose then runs toward the piston, which is moved forward by the air intake. When it’s pushed forward, it creates a vacuum.
The air is then sucked out of the hose and into the cylinder. From there you can attach any vacuum accessories and suck up dirt and debris.
Can I convert the air compressor into a vacuum pump?
It is possible to convert an air compressor into a vacuum pump. It’s easy and simple even with the instruction given in this article, you can do it yourself in your free time.
Which type of vacuum pump is best?
A rotary vane pump is the best vacuum pump for your project if you are on a budget. It is the most common and affordable pump on the market.
What is 2 stage vacuum pump?
A two-stage vacuum pump works on the principle of two rotors and vanes. The first starts the vacuum while the second maintains it and cleans up any residue.
How long does it take for air compressor to build pressure?
It depends on the size of your air compressor and how many accessories you are using at once, like a spray gun or sandblaster. It can take anywhere between 3 to 5 minutes.
How is a vacuum pump useful?
The vacuum pump is very useful in many fields. It is used to suck up dirt, debris, and liquid. It is very useful for cleaning the carpets and curtains.
