How to choose a dental compressor? Tips from MDS!

Selecting a compressor is one of the most important stages in equipping a dental office. Reliable operation of the equipment, patient comfort and long service life of the unit itself directly depend on the correctly selected source of compressed air. In this article, we will tell you how not to make a mistake when choosing a compressor for dentistry.

1. Determine the need for air

The main parameter that interests us is the air consumption of the dental unit. Usually this information is indicated in the technical documentation for the unit. If there is no such documentation, focus on the type of unit:
• Units with a pump aspiration system (dry/wet type) - consume an average of about 50 l/min.
• Injection units in which the aspiration system is powered by a compressor - about 120 l/min.

These data are the basis for calculating the required compressor performance.

2. Calculate total air consumption

Count the number of dental chairs in the clinic and additional equipment (e.g., handpiece lubrication machines). Each device consumes air — this must be taken into account when choosing a compressor.

MDS recommendation: Choose a compressor with a performance reserve of +30% of the total consumption. This will ensure:
• stable system operation;
• reduced frequency of engine starts;
• effective engine cooling;
• increased service life.

3. Deciphering the compressor parameters

In the compressor specifications, pay attention to the actual performance at a pressure of 5–8 bar, and not just the maximum engine power. The compressor operates cyclically — from 5 to 8 bar, so this range is most relevant.

4. Engine power

Pay attention to the engine power, especially if your clinic has power supply restrictions or you use a generator. It is important to make sure that the network can withstand the load.

5. Dryer — a mandatory element

Dry air — the key to long-term operation of the tips and cleanliness of the entire system.
MDS compressors are equipped with sorbent dryers:
• The system absorbs moisture after condensation;
• After each engine cycle, the sorbent is dried automatically (with dry air from the receiver);
• Maintenance — once every six months (replacement of the sorbent and filter).

6. Receiver — not the main thing

The volume of the receiver is not always critical — it is selected by manufacturers depending on the motor power. It only affects the frequency of compressor start-ups. If the compressor is located in a separate room — the volume of the receiver does not play a significant role.

7. Installation conditions

For reliable operation, the compressor must be located in a separate room with supply and exhaust ventilation. The most common cause of compressor failure is overheating.

Conclusion

A properly selected compressor is a guarantee of stable operation of the entire clinic.
Consider air consumption, network capacity, type of dryer and engine performance. And don’t forget about a 30% reserve!
