What Are Compressors Used For?
If you have ever pondered the question ‘what is an air compressor?’, you’re about to get some answers.
An air compressor is a type of machine that draws in air and converts it into an energy source. That energy can then be utilised to operate various types of equipment. As a result, compressed air is a critical resource in many industries.
This blog will explore how and why air compressors are used, acting as a quick guide to help you understand the fundamentals. Let’s jump straight in.
What do air compressors do?
Once the machine draws in the air, it compresses it to a higher pressure. Then, it’s stored in a tank. The stored air can be described as bottled-up energy, waiting to be released. Once triggered, the pressured air can power everything from hand tools to large-scale machinery.

What is an air compressor used for?
Next, we’ll look at the question: ‘what are air compressors used for’?
The truth is that they’re incredibly versatile and have a role in almost every industry. Here are some of the most common uses below:
Manufacturing
Factories depend heavily on compressors to keep operations running around the clock. They’re typically used to power pneumatic tools such as drills, nail guns, sanders, and air impact wrenches. Plus, they’re commonly used on production lines, assisting robotic arms and automated systems. This can replace manual labour and, in turn, may save companies millions each year.
Automotive
Mechanics typically use air compressors for simple yet time-consuming tasks, such as inflating tyres, powering impact wrenches to loosen bolts, and spray-painting cars. Thanks to the consistency of the air supply, a flawless finish is guaranteed almost every time.
Construction
Air compressors are indispensable for powering heavy-duty tools like jackhammers and compactors on building sites. Unlike electrical tools, air-powered equipment tends to be lighter and capable of heavy-duty use. They provide a consistent air flow, which is ideal for jobs on construction sites.
Healthcare
Medical air compressors are used in hospitals, clinics, and dental practices. Professionals rely on these machines to power ventilators and respiratory equipment, through to surgical tools. As patient safety is a non-negotiable, medical industries typically use oil-free compressors to produce clean, medical-grade air that meets hygiene regulations. Where air purity is essential, oil-free compressors are always a go-to option.
Types of air compressors and their uses
Not sure on the type of compressor you need? Here are some of the machines we stock here at Air Supply Manchester:
Piston Compressors
A piston compressor works by moving a piston up and down, which increases pressure. Pistons are often found in small and medium-sized factories, agriculture, and automotive workshops. On building sites, portable piston compressors are popular for running pneumatic tools (which require bursts of power, rather than a continuous flow).
Screw compressors
Screw compressors use two interlocking rotors to compress air and release it in a steady flow. The good news is that they can be used at high speeds and on a 24-hour basis. Plus, as they’re super energy-efficient, companies will benefit from more cost-effective operations.
Industries such as food and beverage and pharmaceuticals depend on oil-free screw compressors to provide clean air in packaging and assembly. In heavy industry manufacturing, screw compressors are valued for their ability to keep automated systems running smoothly.
Scroll compressors
Scroll compressors are built with two spiral-shaped scrolls (one fixed and one moving), which work to condense the air. This type of compressor is compact and quiet compared to other models, making it ideal for businesses with space constraints.
Turbo compressors
Turbo compressors use high-speed impellers to generate powerful airflow and high pressure. They’re typically designed for ongoing, large operations, making them the top choice for chemical plants and food processing facilities.
