CAS-200 Silence

Powerful Aerosol and Micro Dust Collector

Our industry-leading extra-oral Chair-side Aerosol Suction eliminates aerosols and up to 99.9995% of all airborne particulates and pathogens, decreasing the potential spread of infections and diseases.



Prevent airborne contamination

Eliminates dust, saliva, blood, etc., generated during scaling or prep may be sprayed indoors in the form of aerosols, causing infections in hospital staff and patients.

  • ULPA Filter
    Ultra Low Penetration Air (ULPA U15) Filter

    Remove a minimum of 99.999% of 0.1 - 0.2 micron particles that pass through a filter.

  • Super Quiet
    Noise level: approx.55dB (at max level)
    Equipped with a noise silencer

    Less noise brings more comfort to your patient during the treatment

  • Extremely Strong Air Pressure
    (up to 23Kpa)
    Why you need strong Air Pressure?

    In reference to suction/vacuum devices, air pressure is the strength to pull in objects that are in close proximity. Vacuum motor strength alone is not sufficient to pull in objects that are farther away, air pressure is also a key component in the pulling strength.

  • Incredibly High Air Flow
    (140.5CFM, 3.98㎥/min)
    What is Air Flow and why is this important?

    Airflow is the most important measurement when choosing a suction unit. The suction motors with greater capacity of airflow have the power to pull in particles that are farther away. Aerosols are light in mass, therefore, the quality and strength of aerosol suction machines are based on their ability to pull in aerosols that are farther away than those that are closer in distance.

  • UVC + Plasma
    Extra Disinfection Feature

    UVC light to disinfect the ULPA filter and a plasma to kill any remaining germs and bacteria in the exhaust air

  • Reliable & Trusted Product
    Proven Technology in High Standard Markets

    With over 10,000 units sold in South Korea and Japan since 2016, the most trusted product in the market with proven track records.

Reducing The Risk of Infection

Bring peace of mind to doctors, staff, and most importantly to patients

The Covid-19 pandemic has put a focus on air quality in all aspects of our lives, but even more so for the dentists and hygienists around the country. Many contaminants are aerosolized (saliva, bacteria, and viruses) during dental procedures such as crown preparations, sectioning teeth, and especially when using ultrasonic scalers.

Capturing aerosol directly from the patient's mouth is the most effective way to break the chain of infection

Why Extraoral Suction?

Airborne contamination in the operating room

Studies show that the number or aerosol particles (1 micron size) released into a dental operatory can increase up to 158 times after crown preparation.

Reducing the particles with an extraoral suction

Utilizing an extraoral suction with an intraoral suction has been shown to further reduce the number of particles to levels before the crown preparation and significantly reduced compared to using an intraoral suction alone.

HEPA Filters and ULPA Filters

High efficiency particulate air (HEPA) filters and ultra-low particulate air (ULPA) filters are air filters designed to trap a vast majority of very small particulate contaminants from an air stream.

While the US HEPA standard usage of 0.3 micrometer particles to describe efficiency may seem arbitrary, particles of this size are actually the most difficult to filter, rendering them a kind of "worst-case scenario" reference particle.
HEPA filter media is made up of countless randomly-arranged fibers which together form a dense mat; when air flows through the filter, the media captures and contains contaminant particles throughout its depth.

Ultra-low particulate (or sometimes "penetration") air (ULPA) filters are closely related to HEPA filters but are even more efficient. ULPA filters are specified to remove 99.999% of contaminants 0.12 μm or larger in diameter.

Filter Replacement

This ULPA filter is an U15 class filter. The way to check if the filter cleaning is being efficient is to check the suction volume. Repeated filter cleaning means that the fine filter is clogged and filter cleaning is not appropriate at this time. In this case, the secondary ULPA filter needs to be replaced.

Typically, the 2nd filter is replaced every 1 year.

Do not clean the filter directly with compressed air, brush, or water. This can damage the filter material! When installing the filter, be sure to install it in the correct position. Otherwise, leakage may occur.

Steps to replace filters

  1. Move the switch on the upper side of the main body towards the unlock shape.
  2. Hold the arm post and turn it counter-clockwise to release filter cap.
  3. Remove the first filter
  4. Remove the second filter
  5. Remove the third filter
  6. Locate air filter on the back
  7. Remove noise filter from the back
  8. Replace charcoal filter
  9. Replace ULPA filter
  10. Replace charcoal filter
  11. Replace with new filter, and close
  12. Align lines on arm post and main body and turn switch to lock

Steps to Assemble Arm

  1. Insert Silece Artm's rotating post into the arm post on the main body.
  2. Connect Silence Arm to the rotating post
  3. Make sure the spring goes in the back
  4. The back of the Silence Arm is clearly labeled
  5. Attach the clear hood to the Silece Arm
  6. Secure arm with screw turning clockwise
  7. Secure arm position by locking rotating screws on both sides

In order to secure the arm, Slience Arm MUST be aligned with tube properly. Silece Arm's back is labeled with sticker, use it to align it with the box.
