EOS Extraoral Suction System

The EOS system Aerosols and Droplets annihilator is designed and engineered to reduce droplet and aerosol spray that is an innate part of dental care.

During dental procedures Droplets and Aerosols are passed on to the dentist and staff’s bodies.

Patient care and the safety and health of the staff and the dentist is paramount, for the elimination of blood, aerosols and fine liquid particles.  

All of which are annihilated by the ADS EOS system.

​H-14 Hepa Filtration System:  The 3 layered Hepa filtration system, stops virus and bacteria -> 0.3 microns with a 99.995% efficiency.

Precision Water Vaporization Filtering: Ensures the immediate drying in the cabinet base and emits clean dry air.

Medical Grade UV-C Light Disinfectant System: The UV-C light in coordination with the H-14 Hepa filter captures and kills bacteria, germs and virus.

The Heart of the System: Engineering and Design dictated a reliable American made motor that includes advantages such as longevity, noise reduction, negative voltage which is tenfold of the suction power of the central negative voltage.

Precision Control System: Digitized display screen reads out 10 various levels of suction.

Monitoring of Filter Life: Digitized monitoring system displays the life expectancy of the Hepa filtration.

Dual-Use Modes: Ajust suction power level to capture aerosols, bacteria, droplets and splashing blood.  Also used in the disinfecting mode.

Rear Exhaust Design: Minimal noise reduction assuring patient and staff comfort.  Assurance of clean bacteria and virus free dry exhaust.

After use

ADS Extraoral Dental Suction System removes the Droplets and Aerosols effectively, highly reduce the infection risk, keep clean air for the surgery.

Before use 

During treatment,high volume of Droplets and Aerosols produced by high-speed handpieces and ultrasonic scalers,putting the surgery and practioners in high risk of infection.

What is a HEPA filter?
HEPA (High Efficiency Particulate Air Filter)

HEPA is an acronym which stands for High Efficiency Air Particulate, which is made by the fiberglass that is a disorder fibrous mat arranged. The fiberglass caliber is 0.5~2.0 micron and its high level of filtration efficiency for the smallest as well as the largest particulate contaminants can stop virus and germs ≥0.3μm with 99.995% efficiency.

The HEPA filter is developed during the period of the Manhattan Project that belongs to the US Nuclear Weapons Development, and it was used to capture extreme and dangerous radioactive particles. Nowadays, when scientists found out its high efficiency for capturing Droplets, Aerosols, and the particles of Bacteria & viruses, the HEPA filter is used in the medical industry at large.

Will the smallest viruses pass through the HEPA filter?

As the Filtration Mechanisms we learn above, the 0.3 micron benchmark is used in efficiency ratings, because it approximates the most difficult particle size for a filter to capture. HEPA filters are even more efficient in removing particles that are smaller than 0.3 microns and larger than 0.3 microns. The fact that a HEPA filter’s removal efficiency increases as particle size decreases below 0.3 microns is counter intuitive. However, this is a proven and accepted fact in the filtration sciences. 

The virus sizes are within with 0.02um~0.3um. The corona virus size is 0.15um around. Both of them are captured by the HEPA filter through the diffuse and static effect.

​​​​​​​In ISO16890, European standard EN 1822:2009,EN 779:2012 and  DOE-STD-3020-2015 

Specification for HEPA Filters Used by DOE Contractors, all mention HEPA filter H14 is medical grade filter which filter minimum 99.995% particles @ 0.3 microns (PM 0.3) or larger.

Use UV Light To Be a Supplement
UV(Ultraviolet) Light refers to the region of the electromagnetic spectrum between visible light and X-rays,with a wavelength falling between 400 and 10 nanometers. This electromagnetic radiation is not visible to the human eye,because it has a shorter wavelength and higher frequency than the light our brain perceives as images.

UVC-The killer of the bacteria and viruses

EOS is using 254mm lengthwave UVC light that is extremely harmful and almost completely absorbed by Earth's atmosphere.UV radiation can make DNA molecular bond rupture,resulting in bacteria can not breed and die.
Ultraviolet(UV) light kills cells by damaging their DNA. The light initiates a reaction between two molecules of thymine, one of the bases that make up DNA. The resulting thymine dimer is very stable, but repair of this kind of DNA damage--usually by excising or removing the two bases and filling in the gaps with new nucleotides--is fairly efficient. Even so, it breaks down when the damage is extensive.

The longer the exposure to UV light, the more thymine dimers are formed in the DNA and the greater the risk of an incorrect repair or a "missed" dimer. If cellular processes are disrupted because of an incorrect repair or remaining damage, the cell cannot carry out its normal functions. At this point, there are two possibilities,depending on the extent and location of the damage. If the damage is not too extensive, cancerous or precancerous cells are created from healthy cells.If it is widespread,the cell will die.
