42ESU extraoral suction unit

Handler presents the 42ESU extraoral suction system meant to complement the HVE (high volume evacuation) intraoral devices being used during patient treatment. Dental procedures using dental instruments such as low or high-speed handpieces, lasers, electrosurgery units, ultrasonic scalers and air polishers can create bioaerosols that can remain airborne, causing indoor air quality concerns in dental offices.

This biological aerosol contains particles of water, saliva, blood and microorganisms such as bacteria, fungi, viruses and protozoa.

Splatter falls quickly from the air and lands on nearby surfaces, possibly contaminating them. However, droplets evaporate to form droplet nuclei and can remain airborne for up to 30 minutes in a 3-foot area from the source. These small aerosol particles can easily be inhaled by the dentist, the dental assistant or possibly other patients. Due to the small size, aerosol droplets and nuclei can become lodged deep inside the lungs, possibly leading to respiratory infections, nasal congestion, headaches, sinusitis, asthma episodes and development of respiratory illnesses. Possibly respiratory illnesses include the cold, influenza, pneumonia, tuberculosis, severe acute respiratory syndrome (SARS) and other coronaviruses.

The Handler 42ESU can help capture these airborne droplets and aerosols to minimize exposure to harmful agents in the atmosphere. The Handler 42ESU is a device designed to capture aerosol during patient procedures. The double HEPA filtration system will filter 99.97 percent of particles down to 0.3 µm, according to the company. The charcoal filter will assist in eliminating odors. The high-power vacuum motor will move up to 160 CFM through a rigid flexible 2-and-a-half-inch diameter hose and 6-inch round hood opening that can be cleaned and disinfected after each application.
