Disinfection of air: use
Germicidal lamp PROLUX G
®
36W A/DO Portable (Vertical) is used to disinfect air in the presence
of people. Ultraviolet radiation of wavelength 253.7 nm spectrum UVC is used in the disinfection
process. Disinfection occurs when the radiation is applied to microorganisms, which instantly die
due to disruption of their DNA cell structures.
Closed germicidal lamps should be used indoors and its users should minimize the frequency of
opening the entrance door. For effective disinfection of the air, it is necessary to ensure that the
door is permanently closed, if possible. During the process of air disinfection, it is possible to
ventilate the room by opening the window for a shorter period of time.
Germicidal lamps are used wherever air disinfection cannot be ensured by conventional methods
or in environments with increased demands for cleanliness (hospital department for the long-term
sick, department of anesthesiology and intensive medicine, intensive care unit).
Time required to disinfect the air by the lamp:
For optimal air disinfection by the germicidal lamp, the lamp should be used as long as possible in
the presence of people. The air entering through the bottom fan is disinfected inside the lamp by
strong ultraviolet radiation and is then blown out by the top fan. Typical airflow for all PROLUX G
®
germicidal lamps is 60m

/h. Therefore, the lamps do not differ in the volume of pumped air, but only
in the value of ultraviolet radiation. The optimum value is when using a 30W germicidal lamp
(electrical power 30W - 90μW / sec / cm

ultraviolet component). Higher power 72W (110W) is
used in departments with the highest requirements for disinfection (burn ward, transplant ward,
chemotherapy).
In the case of mobile, closed germicidal lamps, the so called “chimney effect” is used - the flow of
warm air upwards - and thus even in case of failure of one or both fans, the process of air
disinfection will not be stopped.
The power output of UVC sources does not affect the volume of disinfected air. The difference is
only in the dose of UVC radiation - the volume of disinfected air is constant.
