What are the different types of dental vacuum systems?

Normal Vacuum System
Normal Vacuum System the suction power is from the dental unit, NO additional auxiliary machines.
The dental unit's suction power depends on air and water pressure. Air pressure control strong suction, water pressure control weak suction.
The advantages of this design is don't need to connect a central suction machine, you can save place and money. The disadvantages of this design is:
1. Unstable and very weak suction power.
2. Easy to block.
3. Expendable resources (water and compressed air).
4. Failure to meet surgical suction requirements.
5. Easy to produce secondary pollution.

Central Vacuum System
Central Vacuum System the suction power is from the additional dental suction unit.
It can make up for all the shortcomings of a normal vacuum system. Now more and more dental practice chooses the Central Suction System. We can say it is “heart and lungs” of your practice. Central vacuum system allows the doctor and staff to keep the oral cavity clean to work in. Having a well-designed and functioning central vacuum system also provides comfort to the patient because saliva and other liquids can easily be evacuated from their mouth during procedures. If your vacuum system goes down, your practice cannot function.

Central Vacuum System with a place selection valve.
About the "place selection valve", it is like a negative pressure switch. When the switch is turned on, the negative pressure will enter the dental unit. When the switch is closed, the negative pressure will not enter. This design will reduce the workload of the central suction machine. Thus, the work efficiency is improved.

If one central suction machine supports more than 2 sets dental unit to work, add the place selection valve in the dental unit is better.
