How air compressors work
Air compressors are machines that convert mechanical energy into the energy of compressed air. According to eluc they serve to compress gas and are divided into low-pressure, medium-pressure and high-pressure compressors.
The working principle is based on mechanically compressing air, where the machine draws in ambient air and gradually compresses it into a smaller space. Piston compressors work on the basis of the movement of a piston in a cylinder, during which the gas is drawn in, compressed and discharged. This mechanism allows a marked increase in pressure and the conversion of ordinary air into useful compressed air.
The key components of an air compressor include:
-
An electric motor or a combustion engine
-
The compression unit (cylinders and piston)
-
A cooling system
-
A pressure vessel (air receiver)
-
Control and safety valves
At Compressors you will find a wide range of models covering nearly all industrial and craft applications.
The main types of air compressor
Air compressors are traditionally divided, according to eluc, into four basic categories: piston, screw, vane and turbo compressors. Each type has its specific characteristics and use in various industrial and craft applications.
According to dspace, compressors can be divided into two main groups by working principle: positive displacement compressors and dynamic compressors. Positive displacement compressors work on the principle of reducing the volume of the gas, while dynamic compressors raise the pressure by accelerating the gas and then converting the kinetic energy into pressure energy.
The main types of air compressor include:
-
Piston compressors: suited to small operations and single-shift running
-
Screw compressors: intended for continuous industrial operation
-
Vane compressors: they use rotating vanes to compress the air
-
Turbo compressors: they work on the dynamic principle of high-speed rotation

Key properties and uses of the individual types
Piston compressors are among the most widespread type of compressor, ideal for smaller operations and craft workshops. They are known for reliability, a low purchase price and the ability to work in intermittent operation. They suit smaller industrial operations, car repair workshops and home DIYers.
Screw compressors are the professional solution for continuous industrial operation. Their main strengths lie in quiet running, high efficiency and the ability to produce large volumes of compressed air. Compressors with a high pressure of 20 bar are ideal for demanding industrial applications requiring a constant supply of air.
Other types of compressor include:
-
Vane compressors: suited to precise and clean environments
-
Turbo compressors: intended for energy-intensive operations
-
Diaphragm compressors: specialised for particular industrial processes
Choosing the right compressor depends on the specific requirements of the operation, including the pressure needed, the air volume, the operating conditions and the economic costs.
Comparison: advantages and limits of the individual compressors
Piston compressors are the traditional solution with clear advantages as well as limits. Their main strengths include low purchase cost, easy maintenance and reliability. Their weakness, on the other hand, is a higher noise level, limited capacity and a shorter service life in continuous operation.
Screw compressors offer considerably higher output and reliability for continuous operation. Compressors with a 10 l pressure vessel allow a stable supply of air with minimal pressure fluctuations. Their disadvantage is the higher purchase cost and more complex service work.
A comparison of the key parameters of the individual compressor types:
-
Piston compressors:
-
Advantages: Low price, easy maintenance
-
Limits: Higher noise level, lower output
-
-
Screw compressors:
-
Advantages: High output, quiet running
-
Limits: High purchase cost
-
-
Vane compressors:
-
Advantages: Precision, clean operation
-
Limits: Higher operating costs
-
Choosing the right compressor requires careful assessment of the specific operating requirements, the expected load and the economic demands.
Common mistakes in choosing and running a compressor
Underestimating the required output is one of the most serious mistakes when choosing a compressor. Many users choose equipment with insufficient output, which leads to reduced efficiency, overloading of the motor and premature wear.
Another critical mistake is neglecting regular maintenance. Compressors without an air dryer require particular attention, because the absence of regular cleaning and checking can cause serious operating problems and shorten the service life of the equipment.
The most common mistakes in running and choosing compressors:
-
Incorrect sizing:
-
Underestimating the output needed
-
Excessive capacity raising the operating costs
-
-
Neglecting maintenance:
-
Skipping regular checks
-
Not draining the condensate
-
Neglecting filter replacement
-
-
Faulty installation:
-
Unsuitable placement
-
Insufficient ventilation
-
No vibration damping
-
Choosing and running a compressor correctly requires careful assessment of the specific operating conditions and consistent preventive maintenance.
