Halton Sentinel UVGI Mobille Filtration
Mitigate the potential for airborne transmission of virus with mobile UVGI solutions from Halton
Halton, using their extensive knowledge and experience in ventilation for demanding spaces (operating theatres and clean rooms), has designed a solution to minimise viral spread and protect personnel and guests in a broad range of indoor spaces with Sentinel.

The American Society of Heating, Refrigeration and Air-Conditioning Engineers (ASHRAE) states that,
“Transmission of COVID-19 (SARS-CoV-2) through air, is sufficiently likely that airborne exposure to the virus should be controlled. Changes to building operations, including operation of HVAC systems can reduce airborne exposures.”
The new Sentinel - Ultraviolet Germicidal Irradiation (UVGI) mobile filtration unit, developed by Halton, complements and enhances the effectiveness of current mitigation practices (social distancing, respiratory masks, hand washing and updated sanitation practices). UVGI has a long history as a tool for minimizing viral spread; it is used extensively in the health care segment.
How does the Halton Sentinel Filtration Unit work?
Through careful selection of UV tube glass and safety controls, the wavelength of the UV light emitted in the Halton Sentinel UVGI unit specifically targets the COVID-19 virus without producing the respiratory irritant, ozone.
Air from the room is drawn into the Sentinel filtration unit for the critical exposure dose of UV to inactivate viral, bacterial, and fungal organisms and then the treated air is filtered through MERV 13 filters for return to the room.
What type of areas are best for using the Halton Sentinel Filtration Unit?
Sentinel is particularly valuable for indoor environments without openable windows where it can reduce the risk of airborne transmission by over 4 times.
“In spaces with lower air change rates, Sentinel offers a solution to provide clean air for comfortable and safe respiration.” says Rick Bagwell, President, Halton Group Americas.
Whether used in a restaurant, healthcare waiting rooms, aged care facilities, office or similar environment, the effect is the same - the Halton Sentinel unit stands guard, destroying viruses and filtering the air to effectively reduce the risk of airborne transmission indoors.
For example, a room with 50 people, requiring 350 l/s of fresh outside air, can receive an additional 1100 l/s of cleaned, virus free, filtered airflow from 2 Sentinel units, effectively reducing the probability of airborne infection by 4 times.
