UV Air Recirculator Defender 2-15 closed type is designed to clean and disinfect air in the presence of people. It can work continuously throughout the day, preventing an increase in the level of microbial contamination of indoor air, regardless of the number of people in it and its category. Defender 2-15 is used for air purification both in hospitals and educational institutions, kindergartens, beauty parlors, and cultural institutions. Also, can be used at home.
The radiation source is two ultraviolet germicidal lamps, which do not emit ozone and are safe for long-term use. The body of the irradiator is made of steel, coated with a special powder paint that is resistant to disinfectants.
Defender 2-15 is mounted either vertically on the wall or on a special stand.
Features of the closed-type bactericidal recirculator Defender 2-15 can operate in the presence of people.
The radiation source is low-pressure mercury discharge lamps, which give short-wave UV radiation with a maximum of 253.7 nm, which has a bactericidal effect. To prevent ozone synthesis, the lamp bulbs are made of special glass, which is impervious to wavelengths around 200 nm.
The service life of UV lamps is at least 8000 hours.
Long-term use in any premises in the presence of people or animals is possible.
General recommendations for using recirculators in closed rooms when working in the presence of people:
In the room, it is advisable to create an inflow of fresh air (from the street), for example, periodically ventilate.
It is not recommended to leave the recirculator turned on overnight, or sleep in a room with the recirculator turned on.
Depending on the volume and category of premises, the following processing time is recommended
Volume of premises, m3
Recommended processing time (not less, min.
Residential apartments, smoking rooms, public toilets and staircases of hospitals
Children's playrooms, school classes, orphanages, homes for the disabled, household premises of industrial and public buildings with a large crowd of people during a long stay
Chambers, offices and other premises of health care facilities (premises of the III category)
up to 60
from 60 to 120
Example: for efficient processing of a playroom with an area of 35 m2 and a ceiling height of 3 m (room volume - 105 m3), at least 180 minutes of recirculator operation are required.
If you need to disinfect a large area, then pay attention to a more powerful recirculator model: Defender 3-15C (with three lamps). For small spaces, there is a Defender 1-15C (with one lamp).
