UVGI 1000

Our UVGI range has a lethal effect with micro-organisms such as viruses and bacteria. SARS-CoV-2, the virus responsible for Covid-19, can be inactivated by exposure to UVGI.

High efficiency

Kill rate up to
99.9% effective

Can be retro-fitted into
existing duct

The UVGI 1000 uses UV-C technology to irradiate virus and bacteria. The unit can be located in line in a new or existing section of ducting as part of the room air distribution. It could also be used as a free standing unit, coupled with a fan, which could be moved from room to room.

Each individual unit sits directly in the air stream and can feature up to 10 high output UV-C lamps.

The number of lamps specified will be dependent on the air volume which will dictate the amount of irridation needed.

UVGI inactivates micro-organisms by attacking their DNA, permanently destroying and altering the molecular structure, leaving them unable to replicate or grow.


  • The ability to provide the units in simple format or fully monitored with each module of lamps able to provide a local alarm or a BMS signal if in fault.
  • Handling of up to 1 m3/sec of air flow.

Ultraviolet (UV) light is measured in wavelengths with the UVC wavelength within the range of 100 nanometer (nm) to 280 nm emitting highly effective sterilization power. UVC germicidal wavelength at around 260nm is the most effective to kill harmful microorganisms in the air and on surfaces.

Our Lamps

Germicidal lamps utilize powerful UVC wavelength to destroy disease causing germs including viruses, bacteria, fungi, protozoa and algae, effectively sterilizing and purifying air, water and surfaces.

UVC disinfection targets the nucleic acid of these harmful cells, rearranging the genetic information, or DNA, and rendering them harmless. As the UVC radiation is absorbed into the cells they become unable to reproduce or multiply to infectious numbers and are considered inactive or dead.

We use tried and tested UV-C technology, after extensive research and development Purified Air are able to devise the best combination of lamps to provide the most effective control.


Ultra-Violet band C light is the most powerful of the three bands, it is a very strong oxidant and as such exposure to UV-C light is dangerous. To ensure safety the UV-C lamps are secured behind locked panels and the system has been engineered to shut down automatically when these panels are unlocked. However, since the lamps typically have a minimum life of twelve months and with the system able to operate at optimum efficiency even if one lamp fails it is unlikely that, apart from routine servicing by experienced engineers, that the system will ever need to be opened.


CIBSE recognise that special UV treatment is efficient for deactivating and killing virus but note that these systems are only normally applied in medical applications. Our focus is to be able to provide cost effective system for commercial applications.
