Air compressors make inflating, powering, and cleaning tasks faster, easier, and more efficient. From tyre inflation and air tools to spray guns and cleaning debris, these provide a reliable source of compressed air for home, workshop, and automotive, and recreational use. At Supercheap Auto, our range includes compact, portable 12V models for on-the-go jobs as well as larger workshop-style units for more durable, high-performance solutions.
What is an air compressor?
An air compressor is a machine that converts power into pressurised air, which can then be used to inflate tyres, operate pneumatic tools, clean surfaces, and more. Air compressors range from small, portable units for quick jobs to large, stationary models for workshops or professional applications. Popular uses include inflating car, bike, and 4WD tyres, powering nail guns, impact wrenches, and spray guns, or cleaning dusty surfaces and hard-to-reach areas. With the right compressor, tasks become faster, more precise, and less physically demanding.
How to choose an air compressor
Choosing the right air compressor depends on what it will be used for and how often. Compact units are perfect for tyre inflation and light tools, while larger workshop-style air compressors handle heavy-duty jobs and frequent use. Portable 12V models are ideal for 4WD, camping and off-road, giving on-the-go power for tyres and tools. Tank size, airflow (L/min), pressure (PSI), noise and included accessories also make a difference in performance and convenience.
Oil-free vs oil-lubricated air compressors
When choosing an air compressor, it’s helpful to understand the difference between oil-free and oil-lubricated models. Oil-free air compressors are low-maintenance and easy to use, ideal for home jobs, tyre inflation and light air tools, with no oil changes required. Oil-lubricated air compressors are built for heavier workloads, offering quieter operation and improved durability for frequent or demanding use. This difference can affect warranty coverage on some models, so selecting the right type helps ensure the best performance, lifespan and warranty support.
Electric air compressors for heavy-duty tasks
Our range of 240V electric air compressors are ideal for home, automotive and workshop tasks, providing consistent power for tyres, air tools, spray guns and cleaning jobs. These units are easy to use, low-maintenance, and suited to regular or heavy-duty applications. Many of our electric air compressor models come with features like pressure gauges, quick-connect fittings and accessory kits to make everyday tasks faster and more efficient.
Portable 12V air compressors for easy on-the-go-use
Our range of 12V air compressors are perfect for on-the-go use, including 4WD trips, camping and off-grid applications. These portable units plug into a vehicle socket or battery, making it simple to inflate tyres, air mattresses, sports equipment and other essentials while away from mains power. Compact and convenient, 12V air compressors are lightweight, easy to store, and often come with built-in accessories to make inflation and small cleaning jobs easier.

Frequently Asked Questions - Air Compressors
How does an air compressor work?
An air compressor works by taking in air and squeezing it into a tank to create pressure. When you turn it on, the compressed air comes out through a hose and can be used to inflate tyres, run air tools, spray paint, or clean surfaces. Essentially, it’s a machine that stores power in the form of pressurised air so you can use it whenever you need.
What is PSI and why does it matter for air compressors?
PSI (pounds per square inch) measures the air pressure an air compressor can generate. Higher PSI means the compressor can push more air through tools and hoses, making it essential for heavy-duty applications like inflating large tyres, running impact wrenches, or spray painting. Choosing the right PSI ensures your tools operate efficiently and safely without overloading it.
What is CFM or FAD, and why does airflow matter for air compressors?
CFM (cubic feet per minute) and FAD (Free Air Delivery) measure how much air an air compressor can supply, which directly affects tool performance. CFM is commonly referenced for smaller 12V compressors, such as portable or vehicle-mounted units, while FAD is the standard airflow rating for larger 240V workshop compressors and represents the usable air delivered at the outlet. Air tools like sanders, grinders, and spray guns require a steady airflow to operate properly, so even with high PSI, insufficient airflow can limit performance, making it important to match both pressure and airflow to the tools you plan to use.
What is a good size air compressor for home use?
For typical home tasks, a compressor with a tank size around 8L to 20L and moderate pressure is usually a good fit. This size handles everyday jobs like inflating tyres, sports gear and inflatables, powering blow guns and staplers, and running light air tools without being too large or heavy. If you plan to use heavier tools or work frequently, stepping up to a larger tank and higher airflow model gives more consistent power and better performance.
Can an air compressor be used for inflating all types of tyres?
Yes, but the required PSI and airflow vary by tyre type. Car and bike tyres typically need lower pressure, while 4WD, SUV, or truck tyres require higher PSI and often more airflow. Using the correct compressor ensures tyres are inflated safely and efficiently without straining the unit.
How do I keep my air compressor working for years?
Regular maintenance keeps an air compressor working safely and efficiently. Drain the tank after each use to remove moisture, inspect hoses and fittings for wear or damage, and follow the manufacturer’s instructions for oiling or filter cleaning if required. Consistent maintenance can help prevent breakdowns, extend the lifespan, and ensures reliable performance.
What are some must-have air compressor accessories?
Essential accessories that make an air compressor much more versatile and convenient include tyre and sports gear adapters, pressure gauges for accurate control, quick-connect fittings for fast tool swaps, air tool kits with blow guns and wrenches, and attachments like surface cleaners or spray guns for cleaning and painting.
