Participants on the course

What does the course look like? 

Those interested in operating compressors must complete the relevant course and pass an examination before an examination board appointed by the UDT. The course for compressors consists of a theoretical and a practical part. Compressor qualifications are issued in the form of a qualification certificate and are valid for five years. After this period, they must be renewed.  


When signing up for our training, you must be at least 18 years old, have at least an elementary education and have a certificate of good health.  

Compressor training programme 

During the course, participants learn about the types of compressors and acquire knowledge on the following topics: 

  • principles of health, safety and fire safety, 
  • automatic pressure control equipment, 
  • performance regulation methods, 
  • operation of equipment, 
  • starting and stopping compressors, 
  • equipment characteristics, 
  • requirements resulting from the UDT regulations for pressure vessels, 
  • breakdown of compressors, 
  • correct operation of compressors. 

What is a compressor? 

A compressor converts the electrical energy of the motor that powers it into compressed gas energy. It can be used for a wide range of tasks, from household machines to large and small industrial plants. The purpose of a compressor is to increase air pressure, and it works by converting electrical energy. It is worth noting that an ordinary pressure washer, used for washing cars, is also one type of compressor. 

What are the main components of a piston block? 

The components of the piston block primarily include:

  • crowding, 
  • piston rings, 
  • crankshaft, 
  • connecting rod, 
  • cylinders, 
  • inlet and outlet valves. 

Maintenance of compressors 

There are different types of compressors that need different parts. However, if we want it to serve us for many years, we must remember to maintain it properly.  

compressor in operation

Regular removal of the water that accumulates at the bottom of the tank is best done after each use. In oil compressors, the water that accumulates in the tank must be treated before it goes down the drain. The oil it contains should be removed. In this case, it is worth equipping the system with a special separator. The air filter and the rest of the filters installed downstream of the compressor should also be checked frequently. The inlet filter should be replaced after about a year or more frequently, depending on the degree of use. Regular checking of the V-belt is another thing worthy of attention. In order to prevent rapid wear, we need to make sure that the tension is correct. It is advisable to check this once a month to ensure that the performance of the machine does not deteriorate or become damaged. A cracked V-belt must be replaced as soon as possible. 

Oil-free compressors 

Oil-free compressors, as the name suggests, do not need oil. For this reason, they require far less maintenance. The only requirements are regular cleaning and changing of the air filter and draining of condensate.  

Oil compressors 

Oil compressors require careful checking of the oil level. This should be done at least monthly, and when necessary - top it up. It is recommended to change the oil annually or when it is contaminated. The same applies to condensate drains and air filters. With this practice, the compressor will function like new for many years. It is also worth remembering that using the recommended compressor oil can affect the life of the compressor.  


Compressors are increasingly used in everyday life. Their low failure rate and efficiency have made them one of the most popular pieces of equipment used in industry.
