In this guide, we’ll discuss how air compressors work – from their basic functionality to the various ways different compressors handle air displacement. Air compressors work by forcing atmospheric air under pressure to create potential energy that can be stored in a tank for later use. How air compressors work can vary according to design.
Air compressors work by forcing air into a container and pressurizing it. Positive displacement air compressors force air in a chamber where the volume is decreased to compress the air. No two air compressors are the same, and finding out how they work allows you to make informed decisions for the project you’re working on.
It’s based on the energy stored in air that’s under pressure, and the heart of the system is the air compressor. While there are small models that are comprised of just the pump and motor, most compressors have an air tank to hold a quantity of air within a preset pressure range. The compressed air in the tank drives the air tools, and the motor cycles on and off to automatically maintain pressure in the tank.
During air intake, air is drawn into the compressor through an air inlet valve. We’ll look more closely at how each type of compressor does this when we cover the compressor types, but two fundamental concepts apply to all compressors. While the air does not have to be cooled before leaving the compressor, most three-phase electric compressors and some diesel compressors come with integrated aftercoolers to lower the air temperature before discharge.
The Low-Pressure Air Compressors operate with a maximum discharge pressure of 150 PSI. Some models of PORTER-CABLE air compressors with electric motors operate at 150 PSI. You’ll see medium-pressure compressors with discharge pressures between 151 to 1,000 PSI. High-Pressure Air Compressors have discharge pressures of above 1,000 PSI. Classification According To Air Displacement. Consider the air volume for your applications before buying an air compressor. It’s important to understand the basics of how air compressors work before installing them.
While most air compressors are designed to handle air at a specific pressure, all of them take advantage of the same basic principle: Boyle’s law. Air compressors exploit this principle to maximize the energy contained in pressurized air.

By understanding how an air compressor works, you can better determine the right air compressor for the job. Whilst there is oil in an oil-free air compressor, the difference is that it’s separated from the compressed air side, making applications oil-free. The compressor uses one piston to compress air in a single stroke, before moving that compressed air to a smaller cylinder for a second stroke from a second piston, doubling the air pressure stored in the tank.
how does air compressor work Related Question:
Do air compressors run out of air?
Rather than running off of electricity, many tools in both the Pro and DIY arsenal run off of compressed air. Compressed air plays a big role in construction, mechanic, and painting applications. In short—don’t skimp on this tool! If you’re just learning how to use an air compressor, don’t stress out.
How does an air compressor compress air?
Air is compressed by air compressors. Air compressors draw in air at an inlet valve, they then compress the air to the required volume and release the pressurised air through the discharge valve into a storage tank. The compression process is usually powered by an electric motor.
Can an air compressor work without electricity?
A compressor doesn’t use any power unless it’s on and running, and that’s important to consider as you evaluate energy consumption and gauge needs. If you’re inclined, you can calculate the cost of the electricity needed to power your compressor — usually in the cents-per-hour range.
How does a compressor increase pressure?
As gas passes through the compressor, its velocity is alternately increased and decreased. During each increase in velocity the kinetic energy of the gas is increased, and during each decrease in velocity this kinetic energy is converted into an increase in pressure.
How long should an air compressor run for?
2.1 states that 1.5 psi pressure loss per 24 hour period is acceptable. We recommend that a compressor cycle no more than 4 times per hour to ensure maximum compressor life, so you are in very good shape with your system.”
Can you run an air compressor continuously?
Only those air compressors with a 100% duty cycle can run constantly at the specified pressure and flow. Running an air compressor beyond its duty cycle limit leads to premature wear and tear, higher maintenance costs and, at its most extreme, breakdowns which can shut down production.
Do you plug in an air compressor?
Air compressors enable the usage of pneumatic tools, which make DIY work a breeze. Compressors are also beginner-friendly, since assembling one is as simple as plugging in the hose and electrical cord.
Do I need a tank for air compressor?
If you have a compressor of any size, you should be using a tank along with it. Air compressor tanks are more than accessories — they are practical additions to your system that provide immediate value for any size unit in any application.
Can you just unplug an air compressor?
Disconnect air compressor from power source and bleed off all air pressure before attempting any maintenance or repair. SHUTDOWN AND STORAGE: NEVER stop the air compressor by unplugging it from the power outlet as this may result in damage to the compressor.
What is the temperature when air is compressed?
Compressed air is no exception; it can become as hot as 300 degrees F. Without cooling, this level of heat can damage equipment, hurt employees and compromise products.
What is the temperature when air is compressed air?
The combination law explains what happens to air when it’s compressed into a smaller volume. It tells us that when air is compressed, the pressure and temperature of the air increases, as the volume of the space containing air decreases.
Does temperature change in a compressor?
The condensing temperature can also fluctuate for various reasons. One reason is that suction pressure differences can affect the pressure ratio of the compressor, which leads to an altered condensation pressure, i.e. a different condensation temperature.
What happens if you leave an air compressor on all night?
Part Failure Should a seal or hose fail at any point in the night, your compressor will run nonstop to try and fill an open tank. If your compressor runs all night without stopping because of a hose split, the risk of a catastrophic motor failure goes up significantly.
Can air compressors overheat?
If your air compressor overheats, it can stop working and need to be repaired or completely replaced. While overheating can happen, there are some steps you can take to prevent common causes of overheating. The most common cause of an overheating compressor is the surrounding temperature and environment that it is in.
Can an air compressor catch fire?
Risk of fire or explosion with air compressor motor Electrical contacts within the air compressor motor or pressure switch can spark, creating a risk for fire or explosion. Serious overheating caused by the restriction of ventilation openings in the air compressor also poses a risk of fire.
