UV Diffusers

Safe Air, Clean Air, Enhanced Ventilation

Prevent the Spread of Viruses and Bacteria Through Ventilation Systems

UV Diffusers act as a shield removing pathogens and allergens from the air coming from the ventilation system before it enters the room. The disinfected and purified air is then mixed with room air with high efficiency in order to reduce the concentration of contaminants. UV Diffusers improve indoor air quality and ventilation efficiency to prevent the spread of airborne diseases.

A Three-in-One Solution

UVC Air Disinfection - UV Diffuser with 2 UV Lamps
1. Safe Air

UV Diffusers sterilize the air using UVC light to neutralize airborne pathogens like viruses, bacteria, and fungi. Thanks to our special plenum which integrates ozone-free UV lamps and its design to increase air contact with UVC rays, we manage to irradiate up to 100%* of SARS-CoV-2, SARS-CoV-1, Tuberculosis, Legionella and many other pathogens.
*Disinfection percentage varies with the air volume passing through the diffuser

UV Diffuser with MERV-9 Filter
2. Clean Air

A MERV-9 filter catches and traps airborne particles including dust, mites, spores and pollen. Filtering the air at the very end of the duct line ensures us that no re-contamination of the air will happen after the filtration process. A common example of re-contamination is dust accumulation in the duct line over time, which can create allergic reactions when the air conditioning system is running.

Improved Ventilation Against COVID-19
3. Enhanced Ventilation

Improving air mixing is what EffectiV HVAC diffusers are designed for. AXO high induction and PLAY adjustable diffusers provide better mixing of the new air with room air, resulting in a faster and more efficient removal of contaminants. Another benefit is a significant improvement of occupants’ thermal comfort. Better air mixing can also help optimizing the performance of the HVAC system and reduce the energy consumption.

Ideal for Retrofits

Compatible with All Existing Systems

Unlike MERV-13 and HEPA filters, UV diffusers add very little pressure to the system. This makes them compatible with existing buildings without needing expensive system upgrades. UV diffusers can replace most existing diffusers without issues, and even improve air distribution performance.

Energy Efficient Solution

UV diffusers disinfect the recirculated air from pathogens with an efficiency up to 100%, which makes it unnecessary to increase the percentage of outdoor air. UV diffusers’ energy consumption is minimal, providing the benefits of using 100% outdoor air at a fraction of the cost.

Safe for Building Occupants

A Safe and Reassuring Blue Glow

UV Diffusers do not produce UV-A nor UV-B, only UV-C rays and blue light. They are designed to contain UV-C rays inside the diffuser and to let only blue light pass through in order to create the safe and reassuring blue glow you can see, symbolic of clean and safe air. The subtle blue glow is also an indicator that the system is working and actively purifying the air.

A Perfect Solution For Commercial Buildings, Including

Safe Ventilation for Office Buildings With UVC Air Disinfection and Filtration
Office Buildings

Safety is one of the main concerns when it comes to employees returning to the office. UV Diffusers help ensure their safety and also reassure employees. They can see that measures are being taken to make sure the air they are breathing is safe. Commercial real estate is facing new challenges and upgrading your office spaces with UV Diffusers can lower energy consumption and operation costs, while increasing occupancy and building value.

Safe Ventilation System to Prevent the Spread of COVID-19 in Schools

Children’s education must continue and precautions are being taken such as limiting children interactions between classrooms. This helps contain potential outbreaks within one classroom only, preventing the virus from spreading between classrooms. There is, however, a risk of airborne viruses spreading through the ventilation system, but we must keep the systems running in order to ventilate the rooms and avoid high concentrations of virus particles in the air. UV Diffusers are designed to stop the spread from room to room and are compatible with existing school ventilation systems.

UVC Air Purification System for Dentists to Disinfect the Air from Viruses and Bacteria
Dental Clinics

Dental offices are one of the most high-risk places to acquire airborne diseases. To ensure the health and security of employees, patients and professionals, proper ventilation is an absolute necessity and UV Diffusers are the solution for sanitization of the air to prevent the accumulation and recirculating of pathogens within clinics. UV Diffusers’ blue glow in the ceiling will reassure patients and staff that pathogen-free and filtered air is being delivered, allowing to breathe with more confidence.

Based on technologies that are proven safe and effective

UV Diffusers ingeniously combine the three proven methods recommended by ASHRAE to ensure safe indoor air quality: good ventilation, filtration, and UV-C germicidal irradiation.

UV Diffusers are not an additive air cleaning technology. They do not emit any harmful particles.

Preventing the Spread of COVID-19 Through Ventilation Systems in Commercial Buildings

SARS-CoV-2 is believed to be airborne and the virus particles are too small to be caught 100% by standard filters, including HEPA filters.

Some studies are being done right now to analyze how COVID-19 can spread from one space of a building to another through the ventilation system of commercial and institutional buildings.

UV Diffusers ensure clean and safe air in every room of the building, and can sterilize SARS-CoV-2 with an efficiency of up to 100% depending on the amount of airflow. They are the last thing that the air passes through before entering the room. Once UV Diffusers are installed in a space, they act as a shield against pathogens and contaminants, protecting that room from the rest of the building.

UV Diffusers are effective against many other pathogens in addition to SARS-CoV-2, including future viruses that we may not know about yet. They are not only a short-term solution against COVID-19, but also prevent by slowing down potential outbreaks from viruses of the future.

UV Diffusers can replace existing diffusers in the whole building, or be installed in a single space. Easy access to ceiling diffusers gives building owners and occupants a lot of flexibility in implementing this solution.

Energy Efficient Solution

Because of the pandemic, ASHRAE and other entities recommend using 100% outdoor air to avoid recirculating contaminated air in the building through the ventilation system.
SARS-CoV-2 is believed to be airborne and the virus particles are too small to be caught 100% by standard filters, including HEPA filters. UV Diffusers ensure clean and safe air in every room of the building, and their energy consumption is minimal compared to heating/cooling and humidifying/dehumidifying 100% of outdoor air. In climates with cold winters and/or hot summers, energy savings can be astronomical.
In addition to these savings, EffectiV high induction diffusers are known to significantly improve air mixing in the occupied space and can help reduce energy consumption compared to other less efficient ceiling diffusers.

For commercial and institutional buildings

Because of their innovative design, UV Diffusers need fewer UVC lamps to achieve the same air disinfection as standard installations in Air Handling Units and ductwork. Because every building already has diffusers and because duct length limitations are not an issue, UV Diffusers can be installed in almost any commercial building with standard ceilings.

Easy installation and maintenance

Diffusers are easier to access than ductwork and air handling units. They can be reached from the room, and UV Diffusers’ hinged face offer easy access to change the filter and UV lamp. Furthermore, UV Diffusers’ light bulb has a 2 year life span with optimal efficiency, while most other UV lamps must be replaced yearly.

Suitable for new constructions and upgrades

Various models of UV Diffusers perform optimally at different air volumes ranging between 50 cfm and 550 cfm, which covers most diffusers in existing buildings. MERV-9 pleated filters combined with UVC sterilization add limited extra pressure and can be handled by most systems without modifying or upgrading the existing equipment*. Data sheets with complete performance data are also available for new designs, along with great support from our network of manufacturer agents.
*Capacity varies for every system, verify first with your contractor or mechanical engineer
