Compressors

What is a compressor?

A compressor is a device used to compress air or other gases by increasing pressure and reducing volume. The history of compressors dates back to the Bronze Age, where the first mechanical compressor was developed in the form of a hand-operated bellows. Nowadays, compressors - also known as compressors - are indispensable tools in various fields, from industry to private use.

Applications of compressors

Compressors find a variety of applications beyond simple tire inflation. They are used to power a wide range of tools, from impact wrenches to angle grinders. Additionally, they are often used for cleaning equipment, computers, or spaces. Depending on the specific requirements of the location and activities, there are different types of compressors suitable for different purposes.

What to consider when buying a compressor?

When purchasing a compressor, it is important to consider the specific requirements of the location and activities. Mobile compressors with extended handles and sturdy wheels are suitable for on-the-go use, while stationary screw compressors are recommended for more demanding requirements in large production halls.

Compressor power

The power of a compressor is measured by the filling capacity, which indicates how much air is delivered per minute. Depending on the requirements of the tools and equipment used, the filling capacity of the compressor should be chosen accordingly.

Oil-free or oil-lubricated?

In some applications, oil-free compressors are legally required, as even small oil residues can render the end product unusable. Oil-free compressors offer numerous advantages, including low maintenance and environmentally friendly operation. They are cost-effective to purchase and avoid special waste in the form of oil residues.

For oil-lubricated compressors, the oil serves various functions, such as lubricating and cooling moving parts, as well as preventing rotor contact. To avoid contamination of the end products with oil, the lubricant is removed through modern filters and oil separators. Oil-lubricated compressors offer a long service life, generate higher pressure, and exhibit less wear.

It is important to note that the maintenance requirements for oil-lubricated compressors are higher than for oil-free variants. The entire compressor must be regularly checked for oil or air leaks, using only approved oils to prevent premature wear of the components. Within the maintenance intervals, compressor hoses, compressor stages, and air or oil filters should be regularly inspected and replaced if necessary.

Pressure requirements and tank size

The required amount of compressed air and tank size depend on the tools used and the nature of the work to be carried out. Most compressors provide compressed air at 8, 10, or 15 bar, taking into account the working pressure of the tools. A larger tank allows for longer storage of compressed air and reduces the load on the motor.

Overall, it is important to consider the various factors to choose the right compressor for the specific requirements and ensure efficient use.
