Specifics of compressors

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, there is a conversion of the electrical energy that has been supplied from the grid to the motor into kinetic energy of the movement of the shaft that drives the compressor block. Further down the line, the conversion of this energy into compressed gas energy occurs as part of the thermodynamic conversion. Compressors are required in situations where it is necessary to increase the temperature of the gaseous medium being compressed or to force its flow, and to increase the density of the gaseous or air medium along with increasing its pressure. They find their application in: 

  • Industry,  
  • technology,  
  • households,   
  • bulk material transport,  
  • 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 

Compressor classification

The operation of this compressor involves the interlocking of two rotors with an incised worm (helical) line, resulting in compression. The line of one rotor enters the cavity of the other, rotating in opposite directions. Compressors of this type are among the cheaper equipment, but must be serviced frequently and sometimes also require a complete overhaul by replacing bearings and seals. 

Centrifugal compressors 

In this case, compressed air is created by increasing the pressure using an increase in air velocity. These machines are oil-free, so they operate differently to the two previously mentioned compressors. They do not require frequent maintenance. Thanks to the absence of pressure pulsation, their operation is quiet and easy. They are more expensive than compressors of other types, but maintenance costs are significantly less.

In 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. 
  • mobility: 
    • portable compressors, 
    • stationary compressors, 
  • drive type: 
    • electric compressors, 
    • hand-held compressors,
  • the type of medium being compressed: 
    • gas compressor, 
    • air compressor. 

Who is this course for? 

Like most of the courses on offer at CSO, it is for almost everyone. To be eligible to participate, you must:  

  • reach the age of eighteen,  
  • have a minimum of primary education,  
  • have no health contraindications to the exercise of the profession.  

We provide training for individuals and for organised groups from a particular company.    

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 under regulations

  • Legal acts specifying the principles of operation and installation

  • Health and safety regulations

  • Fire safety regulations


  • Operation and use of compressors and other devices (compressors, suction cups, blowers, etc.)

  • Compressed air installation

  • Compressor capacity regulation methods


Place of training 

Training sessions usually take place at our centres throughout the country, but we also offer the option of travel to the client by arrangement for corporate training.  

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

Target group, program, location and price of the training

The examination, like the course, consists of a theoretical and a practical part. In order to obtain the licence, it is necessary to pass the whole thing. The test of knowledge and skills takes place before a commission appointed by the ERO. The authorisations obtained are granted for a period of 5 years with the possibility of renewal before expiry. They allow you to operate: 

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