  • *1 Length and Width of the variable arm at 90°.
  • *2 Depends on Battery, life span is roughly 70 to 80% for 300 cycles, 50 to 70% for 500 cycles.
  • *3 The speed changes with the removal rate of the targeted virus. In case of Influenza, the speed is 1 Km/hr.
  • *4 With the single onboard lamp of UV intensity (3.35 mJ/cm2), the Influenza viruses at a distance of 10 cm from the UVBuster were inactivated up to 99.99% within 2.46 seconds.
  • *5 The life span of the UV lamp is 8,000 hours. However, 8,000 hours is the life span at 70% of initial UV Irradiation. As a result, the initial sterilization ability will not be exhibited in the later stages, and it is highly recommended to replace the UV lamp after 8,000 hours of duty. It is also strongly recommended to follow the local rules and safety standards for the disposal process of used UV Lamps or broken UV Lamps.

UVBuster Irradiation Test

The UVC irradiation test was conducted for inactivation of the emerging coronavirus (SARS-CoV-2), using a UVC irradiation robot developed by Farmroid under industry-academia-government collaboration project in Itabashi Ward. The test was conducted at a Corona Examination Laboratory (PCR Laboratory) of Itabashi Hospital attached to Nihon University School of Medicine.

On May 26, 2020, the test on the SARS-CoV-2 samples were conducted. As a result of UVC irradiation, the counts of coronavirus in the examined samples were remarkably reduced. Soon after the test results, Itabashi Ward announced the coronavirus removal effect by UVBuster, which was developed by Farmroid Co., Ltd. Japan for the first time.

UVBuster with remote and self-controlled motion (autonomous) is equipped with 7 + 1 high-power UV-C lamp. Due to the size restrictions of the safety cabinet in BSL-3 facility at Nihon University School of Medicine, the lamp used for the test is a sub lamp of Ultraviolet wavelength 253.7 nm and light output power density of 500 μW/cm2. The influence of UVC at 253.7 nm has been verified in the inactivation of adenovirus, poliovirus, rotavirus, hepatitis A virus, feline calicivirus, coxsackievirus, phage, and influenza virus.

Figure 1 Schematic diagram of the ultraviolet irradiation method.

We were the first group to demonstrate the damage of viral RNA caused by UV Irradiation of wavelength 253.7 nm, resulting in inactivation of Coronavirus.The demonstration was conducted by UVC sub-lamp at 30 cm from the target test sample.The morphology of SARS-CoV-2 irradiated with UVC light for 60 seconds was observed with an electron microscope, but no significant difference was observed with or without UVC irradiation. The amount of viral protein (S protein and N protein) was compared by Western blotting, but no change was observed before and after UVC irradiation. However, by our new qPCR method, we were able to confirm the damage to the viral genome depending on the irradiation time of UVC light rays. A time-dependent decrease in concentration of SARS-CoV-2 was recorded in the experiment.(more info)
