PP-L Product Reference: LSK

The LSK is ideal for medium sized spaces; it uses a highly efficient fan unit ideal for non-industrial air disinfection.

The LSK Active Air Disinfection Unit is one of the world’s most potent Upper Room UVGI Emitters for non-industrial air disinfection. It provides significant air disinfection rates against all known viruses and bacteria, including SARS-CoV-2 (COVID-19). This is known as an active air treatment because of its highly efficient fan unit which draws air from all parts of the room. As with all of our air disinfection systems, they can and should be used 24 hours a day to ensure the highest level of consistent clean air.

Problems with Poor Air Quality

Without adequate ventilation or other interventions, viral loads in an occupied interior environment can build, creating a high transmission risk. This is because airborne viruses (aerosols) can spread inside due to air currents, and then be contracted through the inhalation of these aerosols.

All of our GUV products have a standard two-year warranty. This, however, does not cover any damage caused by misuse or
any mechanical or chemical damage which is not a result of any defect in the workmanship or materials.
We recommend that the light fittings themselves are replaced every 12,000 hours in order to keep their germicidal effectiveness high enough (70% of original irradiation level) to be able to inactivate microbes efficiently at the correct Lethal Dose.
