Why Should Use Extraoal Suction Unit To Remove Droplets _ Aerosols

Dental aspiration systems are now an essential element in any dental practice. There are two types of mobile dental suction systems, depending on whether the air/liquid separation each dental unit or on the suction motor itself. It is important to be familiar with both systems, as the choice of one or the other will affect important elements of the clinic design, such as drains, pipes, heights, etc.

Dry suction systems

The dry suction system takes its name from the fact that air-liquid separation is carried out in dental equipment by means of a centrifugal or decantation separator. In this way, all the liquid is sent to a drain that must be located under each of the clinic’s dental units.

When separating the liquid in each of the equipment, we need one separator and one drain per equipment, but we do not need a drain in the clinic’s engine because only dry air reaches the suction system.

Benefits of the dry vacuum system

Provides good performance: (300 l/min per cannula at 160-200 mbar vacuum pressure)

The suction motor is simpler and more economical.

It is not necessary to drain in the engine

The suction motor can be located at a higher level than the dental equipment.

Disadvantages of the dry vacuum system:

More maintenance is required than for water suction systems.

More devices are needed, as a chair separator is needed.

One must have a drain for dental equipment.

It is more sensitive to the generated foam and suction can even be interrupted for safety reasons.

Water suction systems

In the water suction system, no air-liquid separator is placed in the equipment, and liquids and air are fed to the suction system.

In this system, the suction motor runs dry, but the same device is equipped with an air-water separator. This is more efficient than the one usually used in dental equipment, which ensures that no liquid reaches the motor. Liquids are directed to a drain to be placed in the engine

Advantages of the liquid suction system:

Provides good performance: (300 l/min per cannula at 160-200 mbar vacuum pressure)

The most modern system, it is preferred by most newly opened clinics.

It is not necessary to have a separator for dental equipment.

Maintenance is easier and is only centralized in the vacuum system.

Disadvantages of the liquid suction system:

The suction motor must be at or below the same level as the dental equipment.

One would need to drain in the engine.

If you have any problem in choosing external dental aerosol suction system such as SC-V102 and GS-E1000, you can feel free to contact us.
