Dental Aerosol Extractor (DAX)

Cleaner & Safer from viruses, bacteria, and other pollutants set free during chair-side procedures

DAX is the heart of providing a clean safe environment during dental procedures. Inches from the mouth, DAX efficiently removes the aerosol air/water particles along with viruses, bacteria, enamel dust, and many other troublesome and sometimes downright dangerous particles and/or gas pollutants. It captures these pollutants before they can escape and cause damage. The air is then cleaned and purified from these pollutants before being returned to the operatory.

Frequently Asked Questions

Why is the Dental Aerosol Extractor (DAX) necessary for your dental practice?

How effective is the chair-side air funnel / shield?

DAX has a unique ergonomically shaped and patent pending chairside air funnel/shield designed to capture the air and water aerosol exiting the mouth during Aerosol Generating Procedures (AGP) in the dental setting. It was designed by Dr. V. Kim Kutsch, DMD. who has over 40 years of dental experience treating patients and designing dental products for dental professionals. He has a deep understanding how aerosols exit the mouth. Concerned about the need for an extra oral vacuum designed specifically to capture virus sized particles, his research led to the development of DAX, and its unique funnel/shield.

There are two parts, a funnel attached to a hose and clear see through shield that snaps onto the funnel. The patent pending see through shield is the key to directing and capturing the air and water droplets existing the oral cavity. Clean new shields can easily be snapped into place between patients and sanitized and cleaned later. Because of their low cost they can be replaced often as need be.

Will the hose / funnel be easy to position?
Yes! DAX has a 3-inch diameter semirigid hose that is easily positioned by the dental professional. It will stay in place after positioned inches from the patients mouth during procedures, yet it allows for an unobstructed view and access to the operating field. After procedures are completed it can be positioned straight up to draw air from the top of the room and deposit it at the floor creating a circular pattern for continuous air purification.
What other filtering system does the DAX utilize?
DAX has a carbon filter that also absorbs gases, odors and pollutants. This carbon filter provides for an enhanced air purification program.
Can the HEPA filter trap particles less than 1 micron in size?

Yes, the DAX has a HEPA filter for trapping 0.01 to 100 micron-sized particles. DAX’s air filter will effectively trap particles such as viruses, bacteria, fungus, dust, and other pollutants down to 0.01-micron size. See chart showing types of and size of pollutants removed.

How does is the air flow optimized for effective filtering?
DAX evacuates air at a high rate of speed and volume of air through its 3-inch diameter hose during dental procedures . The diameter of the hose, the size of the air filter/housing, and size of the fan are designed and calibrated for optimized and balanced performance. This velocity efficiently captures the high velocity aerosol created by dental procedures. Safety begins with capturing and controlling all of the aerosol. The balance and power of the uniquely designed DAX can be appreciated as soon as you begin a procedure. It’s why so many dental professionals trust DAX to keep them safe.

In addition, a lower speed of 50 miles per hour and 190 cubic feet per minute can be chosen when dental professionals feel that the lower speed is adequate for that particular dental procedure. Also, a quitter background mode of 120 cubic feet per minute can be chosen. At that speed DAX can clean the air in the whole operatory space every 7 minutes.

Size of Particulate Removed

HEPA stands for “High Efficiency Particulate Air”. HEPA is an official designation agreed to by IEST (United States) , ISO (International), and EN (Europe). Each has its own performance standards and methods of testing for different classifications of HEPA filters. Don’t be confused by terms like “HEPA Type” and “HEPA Like” filters. They all fail the standard. These are purely marketing terms.

Flow Speed and Surface Area

According to a NASA study which deals with particulates in the air during spacecraft travel, a correctly designed HEPA vacuum filtration system would have an air flow velocity of no more than 5 liner feet per minute at the filter interface. This insures the HEPA filter effectively traps the particles smaller than 0.3 microns. The DAX unit is designed and calibrated to meet these requirements with a maximum flow of 3.7 linear feet per minute velocity. This represents the core of the DAX system, by design with combined optimization that coordinates fan speed, filter size and speed, hose diameter, and speed of air at the nozzle. Balance is the key.
