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
- Move the switch on the upper side of the main body towards the unlock shape.
- Hold the arm post and turn it counter-clockwise to release filter cap.
- Remove the first filter
- Remove the second filter
- Remove the third filter
- Locate air filter on the back
- Remove noise filter from the back
- Replace charcoal filter
- Replace ULPA filter
- Replace charcoal filter
- Replace with new filter, and close
- Align lines on arm post and main body and turn switch to lock

Steps to Assemble Arm
- Insert Silece Artm's rotating post into the arm post on the main body.
- Connect Silence Arm to the rotating post
- Make sure the spring goes in the back
- The back of the Silence Arm is clearly labeled
- Attach the clear hood to the Silece Arm
- Secure arm with screw turning clockwise
- 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.
