Portable UV-C air & surface disinfection units

Sentinel UV-C safe air and surface disinfection units are available in 72W & 144W versions



Recommended for use in service-providing facilities (hair and beauty salons), health care facilities, hotels, restaurants, public administration, higher education and care facilities, as well as for private use. Air Marshal staff can calculate UV-C exposure times for each instance. Extra care must be taken to avoid accidental direct exposure to UV-C light.

> Can be fitted with a HEPA filter.


Sentinel air sterilisers are an ideal economical and aesthetic solution to the problem of air disinfection in constantly occupied rooms where exposed UV-C light cannot be used whilst people/animals are in the vicinity. 

They are double-function luminaires – after opening they can also be used for direct disinfection of surfaces (with observance of direct disinfection safety measures – you must leave the room during luminaire operation).

Using forced circulation, air passes through the bottom of the unit and up through the interior of the lamp, where it is exposed to UV-C light and disinfected, before pushed out as clean air at the top. Shielded UV-C light does not escape from the unit, so it can be used in rooms where it can safely and effectively disinfect the air in the presence of people, allowing them to carry-on with their work. This method allows for eliminating harmful microbes from 110 to 160 m3 of air per hour.

Double-function luminaires are an ideal solution for rooms with regular, temporary presence of people – e.g. in medical rooms, restaurants, beauty salons, educational and care facilities, shops and everywhere where there is a constant flow of people during the day and no room occupation at night. After occupancy, the unit’s covers can be opened allowing direct disinfection of the surface.

Air flow disinfection function

Thanks to forced circulation, the air passes through the interior of the lamp, where it is exposed and disinfected, and then pushed out. Shielded UV-C light does not escape from the lamp, so it can be used in rooms where it is necessary to safely and effectively disinfect the air in the presence of people.

*Direct surface disinfection function

After opening the light source’s cover, the lamp should be directed at the surface for a specified time to effectively disinfect it. However, it should be remembered that UV-C light is harmful to the skin and eyes. When using the lamp in this form, no one should be in the range of the light beam. Careful reading of the user manual is required before use.
