You might have heard about the use of air compressors behind the scenes of the production of your vehicle.

But, ever wondered what could compressed air do more?

Playing a critical role in today’s society, you’d be surprised at the extent how some industries depend on air compressors.

The Pharmaceutical Industry

The Pharmaceutical Industry

The wider picture of the pharmaceutical industry involves more than developing potential cures and lifesaving treatments.

As the sine qua non of today’s society, one infected with a cunning virus that’s no match for the human race, a trace of contaminant can lead to hazardous products exposing mankind to much danger.

So, the use of air compressors in the pharmaceutical industry stems from their abilities to ensure precision and cleanliness.

Pneumatic tools are used by professionals for the following:

  • Tablet Production and Coating:

Compressed air is used by laboratory experts to allocate tablets’ ingredients as per their respective formulas and de-dust them. The coating of medicines also requires compressed air.

  • Product Packaging and Bottling:

Even the packaging and bottling of medicines rely on compressed air.

  • Aseptic Applications:

Pharmaceutical facilities now make use of one type of air compressor of the very highest quality, known as oil-free compressors. As a sterile air provider, oil-injected compressors are widely used to reduce the risk of any oil contamination which can compromise the priorities of the industry.

The Agricultural Industry

The Agricultural Industry

We’ve always been hearing how the emergence of the services industry and the full development of the power of AI have led to people bypassing the agricultural industry. As if the agricultural sector was not already spinning for the Covid-19 pandemic to add a new type of crisis on its shoulder.

Fortunately, it is a very robust industry, withstanding the devastating challenges of the world economy.

Farmers today can testify how modern technology is the driving force behind the success of the agricultural industry that generates approximately 2 trillion in revenue worldwide. And, one such technological and professional element behind the increase in food production is air compressors.

Air compressors are usually used in the irrigation of crops, water production, fertilizer and pesticide sprayers, operation of dairy machines, ventilation of greenhouses and inflation of tractor tires.

However, when it comes to the agricultural industry, farmers can only expect a tough compressor with the ability to last longer than others given its extensive usage and potential risk of overheating.

Choosing these types of air compressors doesn’t have to be a difficult process only if you trust the team of experts at Promptair & Electrical Pty Ltd.

The Woodworking Industry

The Woodworking Industry

Let me elaborate a bit.

Compared to traditional woodworking techniques, new and advanced tools have redefined the industry, making it all green and growing.

With the whole idea of creating a more sustainable environment, the woodworking sector has greatly bloomed to become a significant contributor to the global economy, expected to reach a market value of nearly $275.2 billion by 2022.

So, what’s the role of air compressors in this industry?

  • Air compressors can highly increase the efficiency and capability of woodworking manufacturing equipment and tools like drills, nail guns, stain guns, angle wrenches, pulse tools, die grinders and many others.
  • Compressed air is further used to secure pieces of furniture together.
  • Since moving and sorting huge loads of lumber form part of the woodworking industry, compressed air also comes in handy for this task.
  • Air compressors are also used to cut lumber at precise measurements.
  • Using compressed air for coasting wooden surfaces with varnish or finish has been woodworking professionals’ choice for years now.
  • Compressed air is an added benefit when nails need to be inserted automatically.


No matter the type of industry you are in, if you are looking for high-quality air compressors, you need to give Promptair & Electrical Pty Ltd a call.





Workshops using a central power source for driving tools is not a new concept. What has changed, is that air compressors have replaced the belts and shafts that were used previously to route power around the workshop. Nonetheless, the underlying physics has largely remained the same. A certain volume of gas is increased within an enclosure, which in turn increases the pressure, which produces the required power.

Modern air compressors have come a long way from their older, bulkier counterparts. Nowadays, you can easily carry one around, and be sure that it has the required number of designs and configurations to suit several different operational requirements. So, whether you’re visiting the gas station around the corner or a major manufacturing plant, you’re sure to see air compressors being used extensively.

The Basics of Air Compressors

Knowing the basics of how air compressors work is very handy for those starting out on their journey into skilled manual labor. A good place to start would be understanding the underlying mechanics of the system. If you were not aware, air compressors function on the principles of Boyle’s Law, which states that, provided the temperature remains constant, the volume and pressure of any gas are inversely proportional with each other.

Understanding Boyle’s Law

Boyle’s Law was created by Robert Boyle, a physicist and chemist, in 1662. The law has stood the test of time and explains the relationship between pressure and volume.

PV = k simply means that pressure multiplied by volume will always equal a constant. If the volume decreases, you’ll need more pressure to meet the same constant as before (and vice versa).

What Boyle’s Law really tells us is this: as the volume of the space containing air reduces, the pressure increases, if the temperature stays the same. That means that we can increase the pressure of air by forcing it into a smaller space.

Next, let’s have a look at the various Components of an Air Compressor

An air compressor is made up of four basic components. These are:

  1. Electric motor – this component powers the compressor pump by driving a pulley and two belts. The power is transferred from the motor to the pump via a crankshaft and a flywheel. A magnetic starter is also installed here to prevent damage to the motor due to thermal overload.
  2. Compressor pump – this compresses the incoming air and feeds it into the receiver. With 2-stage compression systems, the air is first fed through a larger, low-pressure cylinder, and then into a smaller, higher-pressure one.
  3. Receiver tank – which basically acts as a storage tank for the compressed air, and a receiver valve that prevents the air from flowing back into the compressor pump.
  4. Pressure switch – this is mostly a failsafe that shuts down the motor once the receiver tank reaches its pre-set limit of compressed air.

Aside from these basic components, most modern air compressors have a few more handy components that ensure effective and efficient operation, including:

  • Air dryers and after-coolers to cool the hotter compressed air, and prevent the system from overheating and potentially sustaining damage.
  • Air filtration and moisture removal pipelines, which need to be installed for draining out the condensed moisture from the air compressor system before it reaches the tool.
  • Air lubricator for use in tools that require lubrication. Be careful not to use them for those that don’t, since you can risk contamination.
  • Pressure gauge, which measures and regulates the air pressure to tools. They need to be installed in drop lines for each tool.
  • Shut-off valves need to be installed in each drop line to isolate the accessories from the air compressor for servicing purposes.

The Working of Air Compressors

The working of an air compressor is simple. More and more air drawn into the air compressor causes the pressure to increase due to a higher volume of air being forced into a limited space. When the tank’s designated pressure is reached, the air compressor shuts off, and the air is stored till it’s called into use. This compressed air can be used to power a wide variety of domestic and industrial tools and machines.

It’s impressive to see how a compact device, based on a simple mechanism, can offer so much power. If you’re interested to know more about air compressors, get in touch with the experts at Promptair & Electrical Pty Ltd today.
