Appropriate technologies for healthy and clean air

Today more than ever, our well-being and health depends on the ambient conditions of the buildings and venues in which we spend most of our time.

Centralised air handling systems must include a purification step, whereas in cases where there is no mechanical ventilation, locally applied air purification systems are integrated with ventilation to obtain clean, pure air inside the building.



In closed spaces, opening the windows is not a sufficient guarantee of protection for our health, and most times, it causes discomfort and higher power consumption. Modifying our buildings using centralised systems to improve ventilation is often an impossible investment.

In cases where the external air supply is low, environments can be made more healthy, reducing the rate of pollutants and particles damaging to human health, all while guaranteeing energy savings, thanks to air purifiers and systems known as “upper air”.


It guarantees constant air purification, creating safe spaces in hundreds of venues around the world, since 1990. The efficacy of UV-FAN has been tested and proven to be highly effective against bacteria, mould, and viruses by universities and specialised laboratories.

How it works

The UV FAN series is a range of professional air purifiers that guarantees microbial reduction percentage rates of up to 99.99% for each passage of air inside the device.

  • a silent internal fan conveys the air from the environment to inside the internal mirrored germicidal chamber containing UV-C lamps
  • The inbound air is sanitised and the clean air is re-introduced to the environment, without contaminants.
  • In combination with the UV-C lamps, the devices include two TIOX filters; for the degradation of volatile pollutants and bad odours.
  • the air can be purified 24 hours per day, thus guaranteeing people’s complete protection against airborne pathogens, including bird flu H5N1, SARS, Sars-Cov-2, Herpes, Legionella Pneumophila, TBC, but also Yeasts, Moulds, and Fungi.

The benefits

of UVFAN Purifiers

our range stands due to its advantageous solution because:

Icon Lightprogress

It has the highest UV-C power on the market, and therefore offers the best results in terms of microbial elimination and the greatest number of air exchanges per hour

Icon Lightprogress

It does not generate waste, does not require any particular maintenance unlike filters, which need to be regularly replaced in order to be efficient, and which must be treated like special waste

Icon Lightprogress

It guarantees the same level of performance without reducing its efficacy over time, with proven results confirmed by reliable third parties

Icon Lightprogress

its production is completely internal, thus ensuring greater quality control, while still offering excellent value for money

Icon Lightprogress

It includes extremely quiet fans and a clean design that perfectly blends into any environment

UV-C devices for treatment of upper air layers are recognised and recommended by the CDC, OMS, and ASHRAE as effective solutions to mitigate the airborne transmission of pathogens. The Upper-Air devices are specifically designed to safely disinfect and contribute to keeping the air clean, in a continuous manner.

UPPER AIR Lightprogress

How it works

The devices safely direct the UV-C energy above the occupied space (2.10 m / 7 feet).

  • Improve the quality of the internal air (IAQ) by reducing bio-aerosols, bacteria, viruses and fungi present in the air
  • They work 24 hours per day, 7 days per week, with little or no maintenance
  • They do not produce ozone or other secondary contaminants
  • The units run very silently

Benefits-plus UPPER AIR

Light Progress UV-C germicidal technology is a beneficial solution because:

Icon Lightprogress

It is certified for both its efficacy and safety in the presence of people

Icon Lightprogress

"upper air" technology can be applied in all types of spaces, whether extremely small or open and large (from a small 9 m2 clinic to shopping centres/airports/warehouses)

Icon Lightprogress

It can be easily rated thanks to the expertise of Light Progress, which will guide you in applying the technology, designing the installation layout for the different areas

Icon Lightprogress

It is easy to install and designed to be assembled without any particular effort, in just a few steps

Icon Lightprogress

It is made from extremely high-quality materials and has considerable visual appeal, despite being a highly technical product

Ultraviolet rays are electromagnetic waves which are part of light. Electromagnetic waves are divided into three main wavelength bands, expressed in nanometers, nm: Ultraviolet rays (UV) 100-400 nm Visible rays (light) 400-700 nm Infrared rays (IR) 700-800,000 nm UV rays are in turn identified in three bands:

  • UV-A (315-400 nm) with tanning properties;
  • UV-B (280-315 nm) con proprietà terapeutiche e di sintesi della vitamina "D";
  • UV-C (100-280 nm) with germicidal properties.

UV-C rays (100-280 nm) have a strong germicidal effect and reach their maximum efficacy at the 265 nm wavelength. The germicidal effect of UV-C radiation covers bacteria, viruses, spores, fungi, moulds and mites; this is mainly due to the destructive effect of the UV-C rays on their DNA, which damage their reproductive system and prevent them from replicating.

Bacteria, Viruses, Spores, Fungi, Mould, and Mites are all sensitive to, and can therefore be eliminated with, UV-C light. Mircrobes cannot acquire resistance to UV-C light, unlike that which occurs using chemical disinfectants and antibiotics. UV rays are ecological. Polluting the environment is inevitable using normal disinfectants. Directly inhaling the vapours, or swallowing food products contaminated by any contact with said chemical disinfectants, can also give rise to a number of serious risks. In cases where chemical disinfectants cannot be eliminated (food, pharmaceutical, healthcare industries, etc.), using ultraviolet rays for disinfection allows a reduction in their use, with considerable economic savings and greater care for the environment, while maintaining and almost always improving the level of disinfection. UV-C light devices can be installed in environments and on machinery and be programmed to maintain the same level of disinfection day and night, guaranteeing ideal hygiene conditions, without highs and lows. On the contrary, chemical disinfectants are effective only during their actual use. Using LIGHT PROGRESS equipped luminaires, operating costs are negligible; it could be said that “LIGHT PROGRESS” UV-C systems do not require maintenance except for the normal replacement of the lamps. The cost/benefit ratio is considered excellent; the devices are both powerful and long-lasting. Hence the elimination of germs using UV-C technology is low-cost and highly effective compared to (or in combination with) other systems.

UV-C really does work when applied correctly and with the necessary precautions. The difference between a quality project and an unsuccessful application is in-depth knowledge and experience gained over time. Since 1987, Light Progress has been carrying out successful projects all over the world and has acquired a clientele of major companies in all sectors that require verified hygienic conditions to produce quality products and services.
