What Size Air Compressor Do I Need?

Choosing the right size air compressor for your application is important. As with all large purchases in life, it pays to be well informed. Our 'what size air compressor do i need?' article provides clear and concise information to guide your air compression purchase.

What Can I Use My Air Compressor For?

Air compressors can be used for a range of residential, trade, commercial and industry applications. People, businesses and industry use air compressors for a variety of reasons. At home & for trade use, smaller piston compressor models are often used for tasks like inflating tyres, and other inflatable products and sporting equipment and can handle small, low-load air tools such as pneumatic staplers. The next level is contractor/professional/commercial grade air compressors, which are more powerful and distributes higher amounts of pressurized air. These commercial-grade compressors usually are two-stage reciprocating models or rotary screw models, chosen because they provide power to several tools at once when using intermittently. In industrial applications, air compressors are heavy-duty machines that provide vast amounts of pressurized air to manufacturing facilities, the automotive industry, oil rigs, mine sites and essentially any industry from health, maintenance and transport around Australia. If you are unsure what you can use your air compressor for, read our helpful guide.

How Do I Choose The Right Compressor?

Determining how you will use your air compressor is a great starting point. Developing the list of tools that will function and those tools' applications is the next and vital guiding step.

Selecting the right compressor for your needs depends on the following factors: Determining what application you need an air compressor for; for air tools, trade & workshop or commercial and industrial use. Adding up the total air consumption of all the tools that will be powered simultaneously with the compressor. Determining the recommended operating pressure of your tools and calculating the totals based on the simultaneous use. Planning how to use the air tools - will they be run continuously or intermittently?. The physicality of using the tools, for example, will the air compressor need to be portable, and will there be a power source on the site?.

Types of Air Compressors

The sheer number and variations of air compressors available often require technical understanding to decipher, and due to the size of the investment, careful consideration of the type of air compressor you need is mandatory. Twin Cylinder Air Compressors; Twin Cylinder air compressors contain two air cylinders and are used typically for tools such as trimming tools and nail and brad guns. They are known for being lightweight and highly manoeuvrable, as well are being able to hold a substantial amount of air in their dual tanks meaning the engine engages less often. These air compressors are best suited for DIY enthusiasts and typically used for home projects. Single Stage Air Compressors; The single-stage air compressor is typically available as a portable or stationary model. The portable range has solid engines and pumps but comes with a price reflective of this, while the stationary models suit larger jobs around the household for small jobs and very commonly for auto care. Two Stage Air Compressors; A two-stage air compressor is a powerful machine commonly found in manufacturing facilities and throughout the industry. They get their name from an ability to power multiple tools at one time and come powered by electricity and gas. These units can compress a significant amount of air and power tools such as air hammers, nail guns, impact wrenches and die grinders. This model is typically used in a range of industries due to its sheer power and capabilities. Rotary Screw Air Compressors; These are extremely powerful and very large air compressors typically used in factories, manufacturing facilities and a range of industrial applications. This air compressor is powered by counter-rotating screws which compress air as it pushes through the gap of the screw; this is a very technically advanced piece of machinery that is typically hired or purchased throughout Australia in a wide variety of industries. Piston Air Compressors; This air compressor is available in a range of fuel types (diesel, petrol and electric) and is robust, functional, and has low maintenance costs. The air compressor is designed for continuous duty, made possible by the deep finned cast-iron cylinders and cooler tubes that ensure heat dissipation throughout the operation. Piston air compressors are known as models that operate efficiently and, for those available through Blue Diamond Machinery, comply with Australian safety standards. These air compressors come in a range of HP and PSI variations in addition to small to extensive tank capabilities to keep the machine running for the desired time. Mobile/Portable Air Compressors; These compressors are sometimes referred to as 'mounted' air compressors as they can be mounted onto a skid or trailer for transportation or manoeuvrability. These models are highly versatile, with applications from trade and construction to mining and industrial settings. The machines can range from 17CFM to 200+ and are built using high-quality components, parts & materials to ensure they remain robust and reliable despite their location. Some popular and sought-after features of the portable/mobile models are the 'intelligent system' design which enables the engine to pre-heat without overloading and commence work once optimum conditions surface. The fuel-saving system, by which the system can react to the demands in creating compressed air, results in a significant saving to fuel consumption.
