Guide to Choosing a Compressor

At Stenhøj, we offer a wide range of compressors, but how do you choose the right compressor for your workshop? The following guide takes you through the considerations you should make before selecting a compressor.

Usage

First and foremost, it is important to consider what you will be using the compressor for, as well as the continuous air volume and pressure you require.

Compressors have different capacities, and thus they consume varying amounts of air. Therefore, consider the tasks the compressor will be used for and to what extent. For example, is the consumption of compressed air constant, or does it vary throughout the workday?

How Much Air Do I Need?

To determine the air volume you need, look at the consumption of each tool the compressor will be used with. This is usually specified in cubic meters per minute, liters per minute, or liters per second, along with the corresponding air pressure.

Next, consider how many different tools the compressor needs to power simultaneously. It is generally a good idea to account for the most air-demanding tool, then multiply the consumption by the number of employees expected to use the tools at the same time.

Tank Size

When choosing a compressor, it is also essential to consider that air capacity depends on the size of the tank. A larger tank ensures more air is available, allowing you to operate more tools for longer periods.

Which Type of Compressor Should I Choose: Piston or Screw Compressor?

Whether you should choose one type of compressor over the other depends on the application.

One of the biggest advantages of a piston compressor is its simplicity and reliability. Piston compressors are known for their robust construction and easy operation. They often require less complex maintenance routines compared to other types of compressors, making them suitable for users seeking a reliable and cost-effective solution for air compression. A piston compressor performs very well with varying air pressure needs, and it is therefore the type of compressor most commonly found in a workshop.

One of the key advantages of choosing a screw compressor, in contrast to piston compressors, is that it lacks valves or other mechanical forces that could disrupt the balance of the compressor. This allows a screw compressor to deliver high-quality air at high operating speeds and with a greater air flow. A screw compressor is ideal for applications with continuous air consumption, while a piston compressor is more suitable for occasional air usage.

Oil-Lubricated vs. Oil-Free Compressor

You should also consider whether you would benefit more from an oil-lubricated or an oil-free compressor. The advantage of an oil-lubricated compressor is its longer lifespan, but it's important to note that the oil tank needs to be regularly refilled for the compressor to operate. On the other hand, an oil-free compressor provides the cleanest air and generally requires less maintenance compared to an oil-lubricated compressor.

Current and Voltage

Many compressors need to be connected to a power source to operate, so it is important to consider any limitations related to the power supply. For example, if a specific voltage is available at the power source, you need to ensure that the compressor you choose matches this power supply.
