PHARMA – ASD Extra Oral Aerosol Suction Device.

PHARMA – ASD Extra Oral Aerosol Suction Device.

The PHARMA – ASD Extra-Oral suction device uses high volume Extra-Oral suction to capture, contain, clean, sterilize and kill dental aerosols, creating a safer environment for Dentist, Hygienist, Staff and patients.

The Problem of Aerosols and Droplets in Dental Clinics

Most dental treatments require the use of instruments such as high and low speed hand-pieces, ultrasonic scalers and polishers

During the implementation of these instruments, the combination of compressed air and water can vaporize virus and bacteria particles in the patient’s oral cavity.

High-speed dental hand-pieces and ultrasonic instruments are particularly problematic because of their speed (400.000 rpm or 30 K etc.) and use of water for coolant.

These atomized micro-droplets can drift a range of 1-2 meters around dental chair.

These particles can also be inhaled by the dental professional, staff and other patients.

PHARMA – ASD Aerosol Sterilizing Device.


  • Strong suction pump, large flow, high vacuum, long performance life.


  • Excellent heat dissipation performance, can work continuously for more than 4 hours.


  • Negative pressure could be regulated according to the clinical need by the adjusting knob.


  • Ergonomic design does not get in your way while still providing effective removal of droplets.


  • Low noise, noise level hardly increases when working with ultrasonic scalar, handpiece etc.


  • With strong suction vacuum pressure and high air suction flow rate, the aerosol droplets between the doctor and staff and the patients is sucked into the machine through the adjustable positioning arm, and discharged after thorough purification.


  • The aerosol entering the machine is filtered through HEPA filter and then sterilized by ultraviolet rays. The air is then discharged after a high charged plasma sterilization and purification.

4 stages of disinfection ensure clean air!

  • The built-in high-power blower produces 3M/s wind speed creating a negative air space around the oral cavity, removing dental aerosols and droplets.
  • 4 stage disinfection cleans the air from over 99.97% of vapor, dust, bacteria and viruses.
    • First stage primary filter removes large particles and dust.
    • UV filter exposes viruses and bacteria to UV light breaking down the cellular structure.
    • Plasma generator produces +/- ions charging the particles to make the final stage HEPA filter more effective.
    • Final stage HEPA filter captures the remaining vapor, dust bacteria and viruses.
