Compressor operation course at CSO

Compressor - sample photo

A compressor is an electrical device that increases air pressure by means of energy conversion. This device generates a large amount of heat during its operation. At the very beginning, the electrical energy that has been supplied from the mains to the engine is converted into the kinetic energy of the shaft movement that drives the compressor block. Later in the work, this energy is converted into compressed gas energy as part of a thermodynamic transformation.

Compressors are necessary in situations where it is necessary to increase the temperature of the compressed gas medium or force its flow, as well as to increase the density of the gas or air medium along with increasing its pressure. They are used in industry, technology, households, households or in the transport of loose materials. Compressors can also be useful in pumping natural gas and charging internal combustion engines.

Compressor classification

The main division of compressors takes into account the design of the device and distinguishes three types.

Reciprocating compressors

Their job is to take the right amount of air and reduce its volume. At the same time, its pressure is increased. Air is drawn through the piston. Reciprocating compressors are characterized by a simple structure and low price. Unfortunately, this translates into frequent servicing of the piston and cylinder and a large amount of work involved in replacing spare parts. This compressor is lubricated with oil, which increases the operating costs of the device.

Rotary screw compressors

The operation of this compressor is based on the meshing of two rotors with a cut worm (helical) line, as a result of which compression takes place. The line of one of the rotors enters the cavity of the other, turning in opposite directions. Compressors of this type are cheaper equipment, but they need to be serviced frequently, and sometimes they also require a complete overhaul by replacing bearings and seals, which is not cheap.

Centrifugal compressors

In this case, compressed air is created by increasing the pressure by increasing the air velocity. They are oil-free and therefore function differently than the two previously mentioned compressors. They do not require frequent service inspections. Thanks to the lack of pressure pulsation, their operation is quiet and easy. They are more expensive than other types of compressors, but their maintenance costs are much lower.

Compressor classificationIn addition to the above division, we also distinguish the classification of devices in terms of:

Compression ratio:

  • blowers,
  • compressors,
  • fans

Number of degrees:

  • single-stage,
  • two-stage


  • portable compressors,
  • stationary compressors.

Type of drive:

  • electric compressors,
  • manual compressors.

Type of compressed medium:

  • gas compressor,
  • air compressor.


Who is this course for?

Like most courses offered by SPA, it is suitable for almost everyone. In order to participate in it, one must be at least eighteen years of age, have a minimum basic education and show no medical contraindications to practice. That's just it, we don't require anything more. We conduct training for individuals and for organized groups from a given company. Therefore, if you want to improve your or your employees' qualifications, enroll in a course organized by the SPA.


Training program

The scope of the training includes both theoretical and practical parts.

Theoretical classesPractical
  • Principles of operation of compressors
  • Construction of compressors and principles of their commissioning
  • Requirements for pressure vessels based on UDT regulations
  • Legal acts specifying the principles of operation and installation
  • Health and safety regulations
  • Provisions of P. POŻ


  • Operation and use of compressors and other devices (compressors, suction cups, blowers, etc.)
  • Compressed air installation
  • Compressor capacity regulation methods



Place of training

Trainings usually take place in our centers throughout the country, but we also offer the option of traveling to the client after agreement in the case of company training. The cities in which we have offices are: Warsaw, Kraków, Łódź, Wrocław, Poznań, Gdańsk, Gdynia, Szczecin, Bydgoszcz, Lublin, Katowice, Bielsko-Biała.


What does the exam look like and what are the qualifications?

The exam, just like the course, consists of theoretical and practical parts. In order to receive the qualifications, the whole must be passed. The knowledge and skills are checked before the UDT commission. The granted entitlements are granted for a period of 5 years with the possibility of extension before the expiry of their validity. Thanks to them you can operate:

  • compressors,
  • compressors,
  • suckers,
  • blowers,
  • compressed air installations.
