Types of devices for disinfection of premises
 
Open type devices
The irradiator is an ultraviolet device with a wavelength of 253.7 nm (UV-C), which disinfects not only air, but also surfaces in enclosed spaces. Open irradiators radiate direct bactericidal light from lamps and a reflector (or without it), which affects the entire space around them. Reduces the concentration in the air and on the surfaces of almost all known microorganisms, such as viruses, bacteria, yeast spores, fungal spores and molds and so on. Particularly effective in fighting viruses and bacteria. The device may be equipped with a lamp-change timer. Can`t be used in the presence of people.
 
Closed type devices
The recirculator is a device with a wavelength of 253.7 nm (UV-C), in which the ultraviolet lamps are inside the case, it disinfects the air that is driven inside by fans. The principle of the recirculation consists in pumping air through the housing, which, due to the proximity of bactericidal radiation to the source, achieves a very large dose, which is difficult to achieve in the case of devices of the "open" type, although such devices process large volumes of air at once and for a long time. A high level of disinfection is achieved because the air passes very close to the light source. Recirculators reduce the concentration in the air of virtually all known microorganisms, such as viruses, bacteria, yeast spores, fungal spores and molds, etc. (up to 99%). Designed for continuous operation. Full protection against UV-C radiation. The device may be equipped with a dust filter and a lamp-change timer. Can be used in the presence of people.

Devices of double action (2 in 1)
Combine both the irradiator and the recirculator, they have two separate switches - that is, they can be turned on both together and separately. Help save money and space, as instead of two appliances you can purchase one.

Types of installation / mounting
Devices can be designed for portable use (with a tripod on rollers or on small legs / stands), can also be attached to the wall or ceiling by chains, corners or brackets.
