Dental Exhaust Snorkel Models
The ORIGINAL model is a robust and reliable all-around articulating arm for general applications and fumes, dust, where there is little to no electrical discharges or attack by aggressive chemicals. The extraction arm is shown fitted with a multi-purpose transparent hood.
The ESD/EX model is designed for use in electronic environments where there is a risk of electrostatic discharges. Following risk assessment, the ESD/EX can also be used for certain applications in explosive environments. The extraction arm is made of conductive materials, eliminating the risk of static electricity and sparks. The hood is made of anodized metal.
The CHEM model has profiles made of double anodized aluminum. The articulating arm is ideal for fume extraction in aggressive environments where corrosion resistance must be assured. The extraction arm shown here is fitted with a painted, corrosion-resistant metal hood.
Reduce Airborne Contamination Recommendations
Dental Exhaust Snorkels Capture and Convey Safely of Coronavirus (COVID-19)
Source capture is the most effective and energy-efficient engineering control solution. To ensure proper capture and conveyance of the aerosol, it is vital to have an appropriate arm/hood placement and adequate airflow to create sufficient capture velocity and conveying velocity through the duct.
Dental Exhaust Snorkels Installation Flexibility and Easy to Position
Wherever Works Best for You
The FX extraction arms can be mounted and adequately supported through directly from the ceiling or on the wall. Ceiling mounts save valuable floor space and improve safety by eliminating trip hazards associated with other solutions.
Always in the Right Spot
With the unique ability to swivel the arm 360 at three joints, the hood can be placed at optimal angles to both capture the aerosol and reduce airborne contamination without obstructing the dental clinics procedure.
Benchtop or mount down alternatives is also available.
Dentist Exhaust Snorkels Arm Look, Feel and Function
A lean, smooth, and low-profile design matches medical office environments. The tubes are constructed of anodized aluminum (optional white coating), which is durable but looks great.
Easy to Operate
The arms three joints with 360-degree rotation make the arm easy for clinicians to adjust and move out of the way when not in use.
At the recommended air volume for capture, the FX2 arm noise level is less than 60 dB, which is equivalent to a normal conversation.

Relative Capture Efficiency at Distance and Position
Dentist Exhaust Snorkels Installation Planning
When choosing a mounting location, consider a point from the ceiling that can reach and be positioned appropriately for dentist offices patient care but can also be stored when not in use out of the way.
While exhausting the aerosol is the first choice, it needs to be done safely and avoid re-entrainment. Care must be taken to ensure that the exhaust is not near air intakes or operable windows. Consult industry professionals or local codes and standards for dental exhaust snorkels guidance.
Room Air Patterns
Numerous air patterns already exist within any building resulting from HVAC systems, work being performed, or other factors. When capturing the contaminant, you want to reduce or eliminate cross drafts where possible. If recirculating air, take note of where the HVAC air intake and delivery vents are. Ideally, you want to mix the air and align the airflow patterns to reduce airborne contamination.
Individual vs. Central Systems
Offices with multiple source capture points can have one system per “chair” or a central system. Installation complexity, building construction, power service, energy consumption, and work habits are factors that can influence the best choice for your office. Your Labs USA representative can discuss your needs and provide a recommendation for a system best for you.
Dentist Offices Engineering Control Guidance
Dental Clinics Facilities Handbook 2019
Section 3.2 Dental Care Facilities. “Many standard dental procedures generate aerosols, dust, and particulates. The aerosols/dust may contain microorganisms (both pathogenic and benign), metals (e.g., mercury fumes), and other substances (e.g., silicone dust, latex, allergens). Some measurements indicate that levels of bioaerosols during and immediately following a procedure can be extremely high.”…”Consider using local exhaust ventilation (possibly recirculating with HEPA filtration) to help capture and control these aerosols, because dental care providers and patients are often closer together.”
Section 2.1 Air Quality – Contaminant Source Control. “Certain aerosol-generating activities may also benefit from local control techniques to minimize virus dissemination and other contaminants. Exhausted enclosures (e.g., biological safety cabinets, chemical fume hoods, benchtop enclosures) and localized collection methods (e.g., snorkels, direct equipment connections) are typical control measures.”
Section 2.1 Air Quality Filtration. Some authorities recommend using high-efficiency particulate air (HEPA) filters with test filtering efficiencies of 99.97% in certain areas. Although there is no known method to effectively eliminate 100% of viable particles, HEPA and/or ultralow penetration (ULPA) filters provide the highest air cleaning efficiency currently available.
Dentist Exhaust Snorkels Controlling Exposure to Reduce Airborne Contamination
“Engineering Controls are favored over administrative and personal protective equipment (PPE) for controlling existing worker exposures in the workplace because they are designed to remove the hazard at the source before it comes in contact with the worker. Well-designed engineering controls can be highly effective in protecting workers and will typically be independent of worker interactions to provide this high level of protection. The initial cost of engineering controls can be higher than the cost of administrative controls or PPE. Still, over the longer term, operating costs are frequently lower, and in some instances, can provide cost savings in other areas of the process.”
Aerosol Coronavirus (COVID-19) Solutions
Engineering Controls Solutions
Engineering controls must be considered an additional protective layer as part of an overall strategy to mitigate risks associated with AGPs. No system can assure 100% risk mitigation, and best practice is a multi-layered safety approach per relevant health and safety organizations.
Dentist Exhaust Snorkels Solution Approach
- Utilize a High-Volume Extractor (HVE) system with a high capture hood and articulating an extraction arm to capture a high percentage of aerosol near the source.
- Where possible, exhaust the collected and diluted aerosol safely out of the building.
- When necessary, filter the aerosol using a medical-grade HEPA filter (H13/H14) before exhausting.
- If the exhaust is not possible, filter the aerosol using a medical-grade HEPA filter (H13/H14) and recirculate within the room.
Summary: Dentist Exhaust Snorkels & Coronavirus (COVID-19)
- AGPs create potentially dangerous, submicronic Coronavirus (COVID-19) particles that can linger in the air for extended periods, posing a threat to health care workers.
- Health and safety organizations, including OSHA, NIOSH, and ASHRAE, recommend a multi-layered approach to safety, including engineering controls.
- Source capture is the most effective and energy-efficient method of controlling airborne pollutants, including the Coronavirus (COVID-19).
- Dental exhaust snorkels offer best in class performance for capture, noise level, installation flexibility, and simple to use and operate while matching the aesthetics and clean appearance of dentist offices.
- Once the aerosol is captured, exhausting it outdoors is the first choice. If the air cannot be exhausted safely, filter the air with a medical-grade HEPA filter before exhausting or recirculating the air in the dental clinic.
