UV Air Recirculator Defender 3-15TF 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 3-15TF 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 three UV 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.
The recirculator has a built-in four-digit counter of the operating time of ultraviolet lamps. To clean the air flow from dust (pollen, plant spores, mold, dried disinfectants, aerosols), a coarse filter is used, which reduces the dustiness of ultraviolet germicidal lamps and the inner surface of the recirculator.
Defender 3-15TF 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 3-15TF can operate in the presence of people.
The radiation source is low pressure mercury discharge lamps. Almost the entire radiation spectrum of the lamp falls on a wavelength of 253.7 nm, which has a high bactericidal efficiency. To prevent ozone synthesis, the lamp bulbs are made of special glass, which is impervious to wavelengths around 200 nm.
Air flow filter.
UV lamp hours counter.
The service life of UV lamps is at least 8000 hours.
The illuminator housing is made of metal and can be treated with disinfectant detergents.
Application
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
