UV Air Purifier – UVGI


Cost effective UV Air Purifiers, made and tested in South Africa. CE and SABS approved.

Ultra Violet Germicidal Irradiation (UVGI)

In the mid 1900s the world experienced an increase in TB related infections. Riley & Wells performed scientific trials that proved that UVGI does prevent the spread of TB infections. UVGI was implemented and a reduction in infection was recorded.

Through these trials, the world has embarked in UVGI implementation. The TB pathogen can be airborne for long periods, therefore with the use of UVGI, the air can be sanitized, thus reducing infections. Roderick Escombe ET AL (2007).

What is UVGI?

UV exists in 3 bands:
  • UV A Band – Phototherapy, cosmetic, wound healing
  • UV B Band – Cosmetic (sun tanning), skin disorders
  • UV C Band – this frequency provides the required energy to inactivate the DNA structure in air-borne pathogens (bacteria / virus). Unseen by the naked eye – a meter is used to measure the UVC energy.

Why should UVGI be implemented?

  • To stop the spread of infectious diseases.
  • Increase your productivity by reducing the risk of staff from becoming infected
  • Reduce the burden on National Health for treating infectious diseases by introducing preventive measures.
  • Create an awareness of living healthy by breathing safe air

List of Pathogens that can become inactive:

  • Bacillus Subtilis (spores)
  • Bacillus Anthracis
  • Pseudomonas Aeruginosa
  • Serratia Marcescens
  • Micrococcus Luteus
  • Mycobacterium Tuberculosis
  • Staphylococcus Aureus
  • Escherichia Coli
  • Adenovirus
  • Vaccinia Virus

Example of Test Results:

Johannesburg University tests show a reduction of pathogens by 95%. (UVGI++) CSIR Tests show a reduction of pathogens as per CSIR compliance certificate. Freiburg Medical Laboratory (Middle East) LLC show a 90% reduction of pathogens.


  • High occupation areas, such as municipality rates and taxes, SARS offices, etc.
  • Hospital wards, where nosocomial could occur
  • Enclosed areas, where there is little air-flow
  • Laboratories
  • Doctors waiting rooms, reception areas
  • Community clinics, mobile clinics, ambulances
  • Call centres, offices (occupational health and safety), eg banks, client service cubicles
  • Mines and military that have large dormitories.

How does it work?

The Sani UVGI system is designed in accordance with international UV standards.

A UVC lamp sanitizes the air, whilst a fan creates air movement. The bacteria laden air is slowly sucked into the UVC region and sanitized.

What are your installation requirements for UVGC?

A survey is required to measure an adequate placement of the unit / s based on volumetric area.

As a rule, one burning watt of UVC sanitizes 1m³ of air. Therefore, if a room has a volumetric size of 100 m³, we can deduce that a combination of three 36 watt UVGI units will be adequate for an effective 97% sanitation.

The UV beam and air movement also determines the placement of units required. In the case of dead spots, a wall unit should be used to create air disturbance for effective sanitation.

Ceiling and wall mount units are available.
