What compressor do I need?

The first step in choosing an air compressor is understanding your specific air requirements. Compressed air is often called the "fourth utility" because it’s crucial to many production processes—much like electricity, gas, and water. It’s important to evaluate how much compressed air you need, where you need it, and how often you’ll be using it.

Think about your setup: Are your tools operating one at a time, or do you need multiple supply points? Will they all be running at once? Understanding these factors will help you determine the overall demand, also known as Free Air Delivery (FAD), which is typically measured in cubic feet per minute (CFM).

Types of Air Compressors

There are several types of compressors available, each with their unique strengths and uses.

Piston Compressors

Piston compressors, also known as reciprocating compressors, are perfect for applications that need intermittent compressed air. These are popular for smaller jobs and are great if you need compressed air in short bursts—like inflating tyres or running certain air tools. They’re tough, durable, and deliver high pressure efficiently.

Rotary screw compressors are the go-to option for continuous use. They’re quieter and more efficient, making them ideal for industrial settings where noise reduction is essential. This type of compressors are available in oil-lubricated and oil-free versions, so they can be tailored to your specific requirements.

Oil-free compressors are designed for industries where air quality is non-negotiable, such as food and beverage, pharmaceuticals, and electronics. These compressors eliminate the risk of oil contamination, providing the cleanest air possible.

When choosing an air compressor, keep these factors in mind to ensure you get the perfect match for your needs.

Airflow is critical when selecting an air compressor. It’s measured in cubic feet per minute (CFM) and indicates the amount of air a compressor can deliver. To ensure the best performance, pick a compressor that has a CFM rating that meets or exceeds the requirements of your need of compressed air.

Pressure is measured in pounds per square inch (PSI). Different tools need different pressure levels, so make sure the compressor you select can produce enough PSI to handle your equipment. We recommend adding 15-30 PSI to account for pressure drops that may happen in the system.

The power of a compressor is measured in horsepower (HP) or kilowatts (kW) depending on where you live. Make sure you choose a compressor with enough power to handle your workload. More power means more consistent performance and longer compressor life.

The duty cycle tells you how long a compressor can run before it needs a break. Compressors with a 50-60% duty cycle are best for occasional use, while those with a 100% duty cycle are built for continuous use.

The size of the tank will affect how long you can use the compressor before it needs to cycle. Smaller tanks work well for tasks requiring short bursts of air, while larger tanks are great for continuous use.
