Having the best air compressor is essential for every home workshop. It doesn’t have to be anything fancy, but it should be good enough to use for a variety of purposes. Though one can easily buy one in the market, not everyone is willing to spend $100 to $150 on the best air compressor.

In this article, we take a look at how to go about making a homemade air compressor that can take care of a variety of needs, such as inflating a tire, using it for blow-dry parts, and even for automotive spray paint. So, without further ado, let’s figure out the different ways one can make a small air compressor.

How Does An Air Compressor Work

Basically, it is a twofold process, which involves a rise in air pressure and a drop in volume. Mostly, the compression is achieved via a reciprocating piston technology, which is how most of the products available in the market work. They are also powered mainly by either gas or electric motors. At the ends of the cylinder are discharged valves and the inlet. The inlet sucks in the air, which the piston compresses, which is then released through the discharge valves.

Some compressors use pressure produced with rotating impellers. The best air compressor used by construction workers and mechanics runs on positive displacement, which relies on compression within compartments. Though some of them have a motor and a pump, most of them have air tanks. Its purpose is to store air needed to power the tools connected to it. The motor, meanwhile, starts and repeatedly stops, thereby keeping the pressure within specified ranges.

The piston, with its back and forth movement, creates a vacuum. When it retracts, space before it is filled with air, which then is sucked through the inlets, when it extends, the air is compressed and therefore given the strength to push through the discharge valve. The pressure gains intensity as more air is sent into the tank.

What Can You Do With An Air Compressor

You may be interested in building an air compressor if you regularly engage in crafts, building, or carpentry. A pneumatic nailer also uses such an item to power it. They make spray-painting jobs a breeze, especially if you have the best pump sprayer. Furthermore, with such a tool, you can even complete auto repair jobs by yourself. In combination with ratchet tools, it can get you to remove tough bolts in just a few minutes.

Typically, various jobs can be taken care of if you decide to build your own air compressor. These include inflating car and bike tires, powering the best leaf blower, or other devices that can clean brick, stone, or house siding. Air compressors can be used to power hammers, wrenches, and even saws. One can even have a homemade pressure washer with air compressor.

DIY Air Compressor

Now, let us take a look at how to. In total, we shall take a look at three different ways in which you can have a silent air compression DIY, and these are as follows:

How To Make An Air Compressor From An Old Refrigerator

First up, ensure that all refrigerant is evacuated from the refrigerator’s system. Cut the copper tubes using a tubing cutter once the gas is out of the system. Make sure that you leave as much length of copper tubing as possible and do not leave the tubing upside down.

Next, separate the terminals on the capacitor by following the power cord into the wiring harness. Mark the wires and the terminals to keep the configuration. These will go into another set of terminals on the 110V pump.

Thereafter, connect the corresponding wires to the capacitor and the green ground wire to the base of the pump. Bend both copper lines on the pump and point them vertically without kinking them. Keep away from walls and ceiling, plug-in, and listen for the motor sound. Air compressor pump and motor assembly are important in the whole process. It is normal for one copper tube to spit out oil at first.

If the oil doesn’t blow while the unit is running, finger the copper line ends and feels for a vacuum. Mark the line that doesn’t have a vacuum as the supply-line. Attach this with a hose and clamp to a fitting connected to a four-way “tee” with a safety release valve, air gauge in line to a three-way “tee” in line with an air tank. Install a female chuck on one leg of the three-way “tee” for the hose to inflate your tires and your tools.

How To Build An Air Compressor From Scratch

If you’re wondering how to make a homemade air compressor from scratch, then read on and follow these steps.

Firstly, acquire the pump, a vessel or tank, copper tubing, and compression fittings – all things which will be you will need for construction air compressor. Thereafter, connect the compression fittings to the pressure lines (copper tubes bent vertically). Have a valve block with a pressure gauge and a relief valve and install a cutoff switch that cuts the power once the pump reaches an absolute pressure.

Next, cover the capacitor terminals of the compressor pump with rubber to insulate you from the bare wire. Lastly, seal the system and pressure test. For this, put the compressor on an extension cord and let it run until the opening of the relief valve. Once the operation of the system is deemed safe, you can use your homemade air compressor tank for various purposes.

How To Set Up An Air Compressor?

Once you have understood how to build an air compressor, it is time to understand how to set it up. The best air compressor can work only if you’ve set it upright. First up, check the pump oil level and ensure it is 2/3rd full. Next, attach the hose to a regular valve and plug the power tool into the hose. Lastly, plug the compressor into a grounded 3-prong outlet, and you’re good to go.

We hope that through this article, you now know how to make the best air compressor. Though making air compressor requires certain materials, these can be availed with ease from a junkyard or a local hardware shop.
