How to Use an Air Compressor

Some time ago, you would find air compressors in workshops or someone’s garage. They were too big to be kept anywhere else, and they weren’t so easy to operate. But since our world is evolving rapidly, everything is changing and becoming smaller and handier to use; this includes air compressors as well.

Now that different smaller types of air compressors are available, people efficiently use them in the comfort of their homes. No longer do they only need to be used by professionals. If you do not know how an air compressor works, then read on.

How does an air compressor work?

Air compressors work by keeping compressed air in a tank (made up of steel), which is then released (in a very controlled way) to help different function types of tools. Some of these tools include grinding and sanding equipment, air wrenches, and even some painting tools.

There is an electrical motor attached to the unit that pumps the air into the tank. Since this process is done under pressure, there is enough of that to make tools work. The air hoses you find will be used to connect the tanks to the devices to get them to function. Most compressors shut off automatically if the air pressure inside the tank starts to fluctuate. There is a limit that has been set for each container, and once the pressurized air reaches that level, the motor will shut off.

If you feel the need to use tools operated by air compressors, then the best option to go for are pneumatic tools; these tools can be run with just one air compressor. Other tools will probably require their type of air compressor. The attachments you will need to operate with the air compressor are not expensive and will fit your budget perfectly. Another thing you might not know is that hand-held tools are not as powerful as pneumatic tools.

Many brands manufacture air compressors, and most of them are well-known for their durability and power. If you look at the mechanical engineering of air compressors, then you will notice that they are available in many different designs; some of them need oil to work because they have automotive type pistons.

Whenever you see an air compressor of a piston style, then you can be sure that they are of high power and are used for operating large tools. If the work is not too big, then the best option to use is the diaphragm type compressors. These do not use any oil; instead, they work by making a seal by using a diaphragm made of rubber. Also, these compressors, since they do not use any oil, are very popular, and most home-based workers own these. They are best used for working with small equipment.

7 easy steps how to guide

Some of the necessary steps to use air compressors have been discussed, and they will be useful to use for almost any type of air compressor.

How to use an air compressor

  1. Plug it in

    The first thing you need to do when using an air compressor is to plug it in. Make sure that you keep the machine on a flat area, which is also sturdy, so it does not break under the weight of the machine. Before you plug it in, ensure that the power outlet’s switch is off. The plug will be three-pronged, so make sure that you plug it into a grounded outlet.

  2. Check the oil

    You will then need to check the oil of the air compressor. However, this step is dependent on the type of air compressor you have; if it is a piston-type, then ensure that there is plenty of oil inside the crankcase before you start to use it.

    The best way to check the oil is to look inside the sight gauge, which is located at the bottom of the motor. If need be, then take off the oil filler cap and fill the oil till it is full. You will know this when it reaches the mark. Make sure that you keep an eye on the level of the oil every time you use the machine.

  3. Fill the air tank

    Fill in the air tank; you will need a wrench to tighten up the drain valve (located at the bottom of the tank) so that the air you fill in does not escape. Make sure that you rotate the wrench clockwise. After that, you will need to turn the machine on and let it run for some minutes.

    You will find an air gauge on the air compressor, check that you make sure that the compressor shuts itself off when the air pressure has reached about 100 or 115 PSI. However, check your air compressors model to determine the exact pressure capacity of the air tank and let it shut off accordingly.

  4. Adjust the control valve

    You will find an air control valve on the machine; make sure that you adjust it (the max air pressure allowed) to them according to the tool that you are about to use. You can accomplish this task by turning the air control valve until it fits the air pressure required.

  5. Connect the air hose

    Now you will need an air hose and connect that to the air compressor. Remember to keep the length of the hose long enough that it does not disrupt your work; it reaches the work area safely and adequately.

    When you fit the hose to the compressor, make sure that you wrap it with Teflon tape (two layers). Then you will need to thread the tube on the fitting of the compressor. You will then need to tighten the connection with a wrench; twist it clockwise.

  6. Connect the tool

    On the other end of the hose, you will need to connect the tool that you plan on using. Mostly you will find quickly connect fittings to accomplish this job. You will find a spring-loaded collar on another end of the hose, pull that back, place it on the air intake part of the tool, and push. Once you let go of the collar, the connection will become secure. If you want to take off the tool, then pull the collar back and pull the tool off the hose.

  7. Draining

    Since air compressor tanks tend to gain moisture, make sure that you drain all of them off periodically. Go through the instruction manual for this process. However, as per standard practice, you will need to take off the drain valve and drain it. Once you are done, tighten it back on.
