UV Air Recirculator Defender 3-30 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 3-30 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 a germicidal ultraviolet lamp that does not emit ozone and is 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 3-30C is mounted either on the wall in a vertical position, or on a special stand (not included in the package, supplied separately).
Features of the closed-type germicidal recirculator Defender 3-30C can operate in the presence of people.
The radiation source is a low-pressure mercury discharge lamp, which gives short-wave UV radiation with a maximum of 253.7 nm, which has a bactericidal effect. To prevent the synthesis of ozone, the lamp bulb is made of special glass, which is impervious to wavelengths around 200 nm.
The service life of the UV lamp is at least 9000 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.
