Frequently Asked Questions


Our devices are powered by a silent fan absorbing the air from your room, pushing it through various filtration levels and blowing clean air out again.

The AIR8 devices have between 4 and 6 filtration stages which include pre-filtration, HEPA filtration, carbon filtration, cold catalyst, UV-GI light as well as ionisation. Thanks to this cutting-edge air disinfection devices, 99,97% of all air particles are being removed from the air.

HEPA, which stands for High-Efficiency Particulate Air, is an efficiency standard for air filters.

HEPA filters were first created during World War II, to enhance the filtration process of gas masks. Later they were used to prevent the spread of radioactive contaminants floating in the air. Over the decades, the HEPA filters evolved and started to be used in various high technology industries such as aerospace, manufacturing that require contamination control, hospitals, homes and vehicles.

HEPA filters are highly effective in capturing 99,97% of fine particles that are 0.1 microns and smaller. According to NASA reports, this size of particles is considered to be the most penetrating particle size, therefore the most dangerous one.

The HEPA filter’s microscopic fibre maze consists of interlaced glass fibres that are twisted and turned. The small size particles are caught by the diffusion principle when floating through HEPA filters. By hitting and sticking to the sides of fibres, these particles are trapped and therefore not harmful anymore.

HEPA filters capture 99,97% of coarse, fine and nano particles lingering in the air, such as viruses, bacteria, allergens and air pollutants.

When combined with other air filtration technologies (such as carbon filters, cold catalyst and UV-GI light), 99,99% of all lingering particles are captured and eradicated.

The microscopic fibre maze of the HEPA filter efficiently captures fine particles, even as small as 0.001 micron. The Coronavirus itself is 0.1 – 0.2 microns, moreover it travels through the air on larger respiratory droplets, therefore it is easily captured by HEPA filters.

The demand for better air quality has been growing over the past decades. Air filtration systems are commonly used in aviation and the medical sector, also more and more often in working spaces, retail, hospitality, as well as in private households.

The UV-GI light is an unrivalled technology that sterilizes 99,99% of particles. The ultraviolet light (UV-GI light) eradicates unhealthy microorganisms, viruses and bacteria. Once destroyed, these accumulated microorganisms can no longer multiply in the filter.

The UVGI light technology has been used in healthcare environments in order to disinfect spaces when unoccupied. The UVGI lights are safely built-in and exposed only to the HEPA filter; making it 100% safe and compliant with EU directives.

Yes, AIR8 solutions are carefully developed and manufactured in accordance with all EU health and safety directives. The UV-GI light is safely built in and only exposed to the internal current. Our devices are 100% ozone free!

Ozone Generators

Ozone is active oxygen, O3. It occurs naturally in the earth’s atmosphere to protect us from the sun’s harmful rays. When an O2 molecule gains another oxygen atom, it becomes ozone. It is an extremely unstable state for oxygen, which is why it makes such a powerful sanitizer.

The third oxygen atom in the ozone gas makes the ozone gas highly reactive. This active oxygen atom reacts with odour-causing molecules to oxidize volatile organic compounds, or to destroy these microorganisms by breaking down the cell wall of microorganisms in the environment. This process is called oxidation. Since ozone gas turns into oxygen (O2) molecule after oxidation, ozone gas is known as an extremely environmental disinfectant.

Although there are many academic studies and methods related to ozone gas production, it is possible to divide the methods of ozone gas production into 4 basic categories. These methods are Corona Discharge, Cold Plasma, Electrolysis and UV methods. In all the methods mentioned, O2 molecules are broken down to form distinct single oxygen atoms. The single oxygen atom (O) combines with O2 to form ozone gas.

Ozcon Ozone Generators use corona discharge method for ozone production. Industrial units adopt Micro-gap dual corona discharge technique. Kitchen ozone generators and portable generators adopts ceramic dielectric corona discharge technic.

Yes and no. It is extremely simple to design or manufacture a device that produces ozone gas. You can visit various video streaming sites to research this subject.

Amateur manufacturers produce various devices that produce ozone gas with their own means, but producing an ozone generator for an industrial facility requires a different expertise and knowledge.

By making a device that produces ozone gas, it is very different to produce an ozone generator that complies with international standards, is controlled with safety sensors, produces ozone gas with the capacity written on it even under minimum conditions, does not produce any harmful by-products, and is compatible with the automation system, made of ozone gas resistant materials. process.

With the right method, ozone generators that are not manufactured to international standards can produce many harmful by-substances. As it is known, there are many different gases and substances in the air apart from the oxygen (O2) molecule. The most common of these are nitrogen (N) gas.

Within the framework of EU regulations, all ozone generator manufacturers within the EU have been removed from the machinery manufacturers class since 2012 and included in the biocide regulation. The main reason for this change is the production of a high quantity of NITRIC ACID and NITRIC OXIDE (NOX) seen in products produced by incapable manufacturers.

Yes. In nature, ozone gas is constantly present between 0.01 PPM and 0.03 PPM.

Of course, the ozone gas used for disinfection purposes should be delivered in a human environment in a controlled manner and managed with ozone monitors and sensors.

No. There are no scientific studies proving that ozone gas causes permanent damage to human health.

Ozone gas has entered our lives in medical and industrial fields for the last 30 years, but ozone gas is a known molecule for 200 years. For this reason, many researches and scientific studies have been conducted on ozone gas. International organizations such as Occupational Safety and Health Administration (OSHA), World Health Organization (WHO) and the US Food and Drug Administration (FDA) have set ozone gas limits.

Side effects such as burning in the eyes and nose, headache, sore throat, nausea can be observed in the case of 8 hours of exposure to ozone gas at 0.1 PPM. However, none of these side effects is permanent.

As Ozcon, we recommend the use of ozone measurement and control systems to avoid any undesirable problems in ozone applications to be made in production areas.

Yes. 99% of the water, bottled or demijohn water we buy is disinfected with ozone gas.

Measuring ozone gas is extremely important, especially in industrial applications. As we have emphasized in every project, “We cannot manage what we do not measure”. We are obliged to follow our generators with ozone measurement sensors that control the ozone gas concentration 24/7 in order to control the ozone gas, which is an extremely aggressive gas, to give the area in a dosage suitable for the prescription, to provide maximum efficiency from the ozone gas and to minimize the corrosive effect of the ozone gas.

Ozone monitors measure ozone gas concentration in PPM (particles per million). Just like ozone generators, these sensors must be produced and calibrated in accordance with international standards.

Electrostatic Precipitators

The Electrostatic Precipitator (ESP) unit utilises the principle of electrostatic precipitation. The dirty exhaust air is drawn onto the mesh pre-filter which traps large grease particles. The remaining finer particles some small as 0.01-micron pass into a strong electrical field (ionising section) where the particulate receives an electrical charge. The charged particulate then passes onto a collector plate section made up of a series of parallel plates. Each alternate plate is charged with the same polarity as the particles repel are grounded, which attract and collect.

Yes! The first rule for electrostatic precipitators is, the higher the velocity the lower the efficiency. The faster the exhaust air travels through the ESP unit, efficiency is compromised. Decision-makers should consider the physical size of the ESP unit, pre-filters, electrostatic cells.

Ozone generator is installed after the electrostatic precipitator. It generates ozone gas and brakes down grease and odour containing compounds producing during cooking. Ozone reduces oil and grease build up in kitchen exhaust ductwork and reduces fire risk. When the Electrostatic Precipitator is in operation and the ozone generator is automatically turned on.

Yes. Expansion Electronic manufactures and provides the most tested and certified Electrostatic Precipitator Technology in whole world.

Single-pass efficiency collects up to 98.4% efficiency and double pass efficiency which exhaust air is passed through two units giving it an efficiency of 99.9% and for modular filtration systems, the Ozcon ESP units can be stacked on top of each other to increase airflow (L/s) requirements.

ESP units should be installed as close as possible to the commercial kitchen canopy. This positioning reduces the amount of oil and grease which can accumulate in the ductwork. If your only concern is smoke or you don’t have a place to install it close to canopy you can install it outdoors.

Every cooking style is different, however, on average, the following cleaning schedule applies. These are based upon standard restaurant opening hours:
• Light cooking: every six weeks
• Medium cooking: every four weeks
• Heavy cooking: every two weeks or weekly for charcoal/ solid fuel cooking

2-3 m/s is the best airflow velocity and any higher the electrostatic precipitator won’t be efficient enough and efficiency will be greatly compromised.

UV Systems

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

  • UV-A (315-400 nm) with tanning properties;
  • UV-B (280-315 nm) with therapeutic and vitamin “D” synthesising properties;
  • 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.

These lamps have an emission of around 90% over the 253.7 nm wavelength. This frequency is invisible to the human eye and has a strong germicidal power. The remaining 10% of the lamp’s emission is visible (typically appearing as a blueish light).

Yes, UV-C rays are found in nature as they are generated by the sun, but the ozone layer in the atmosphere acts as a shield which stops them from reaching the earth’s surface.

Bacteria, viruses, spores, fungi, moulds and mites are all sensitive to UV-C rays and can be eliminated by them.
Microbes cannot acquire resistance to UV-C rays, which only occurs using chemical disinfectants and antibiotics.
UV rays are eco-friendly. When using normal disinfectants, environmental pollution is inevitable. They also carry severe risks from the direct inhalation of vapours or the ingestion of foods contaminated after coming into direct contact with chemical disinfectants.

Where the use of chemical disinfectants is unavoidable (food/pharmaceutical/healthcare industries, etc.), using ultraviolet rays in the disinfection process can reduce the amount needed, which allows for significant cost savings and is better for the environment, while maintaining – and, most of the time, improving – disinfection quality.

UV-C ray devices can be installed in most environments and machinery and can be programmed to maintain the same level of disinfection day and night, ensuring ideal conditions of hygiene without any fluctuation in quality. In contrast, chemical disinfectants are most effective at the time of use.

LIGHT PROGRESS UV-C-equipped devices offer low running costs and are maintenance-free, besides normal bulb replacement. These powerful and highly durable systems provide exceptional value for money. For this reason, eliminating germs using UV-C as opposed to (or together with) other systems offers excellent results at a low cost.

UV-C rays really work. The difference between an ineffective application and a quality project lies in our in-depth knowledge and long-term experience in the area. Since 1987, Light Progress has successfully completed projects all over the world and built-up a portfolio of clients, including companies from all industries that require verified conditions of hygiene to produce quality products or services.

Multiple organisations and boards with a global reach, such as WHO, EPA, CDC, ASHRAE and many others, recommend using UV-C rays to disinfect water, environments and air-conditioning systems. LIGHT PROGRESS is a member of the IUVA (International Ultraviolet Association), a global organisation that collects and gives users access to all available information and which organises various international meetings each year. Having collected all this information, the IUVA has also published a document which lays the foundations for designing different UVGI (Ultraviolet Germicidal Irradiation) systems and applications.

UV-C rays are used every day, primarily in:

Food and pharmaceutical industries, for disinfecting air and surfaces in production spaces, disinfecting product containers (packaging), isolating “protected” areas for product manufacturing and packaging (such as clean rooms), and areas at risk of contamination. These procedures significantly increase the safety and conservation of the products we purchase and provide multiple health benefits since they leave no residue and help reduce or even eliminate the need for chemical disinfectants, which can leave harmful residues on products.

Hospitals, for preventing the transmission, and therefore contagion, of dangerous bacteria or viruses that may be found in the air or carried following contact with infected persons or visitors, such as TBC and Legionella.

Air conditioning systems, for preventing the problematic and harmful build-up of mould and bacteria in air treatment systems or ducts, which can cause Building Related Illnesses (BRI), extrinsic allergic alveolitis, viral, fungal and Rickettsial infections, bronchial asthma, humidifier fever, Pontiac fever and Legionnaire’s disease, asthma and Sick Building Syndrome. Many armies use UV-C systems to prevent biological attacks such as the dispersal of anthrax in pipelines.

Systems for treating water intended for human and animal consumption and for sanitary use, to eliminate any microorganisms that may be found in water deriving from wells, cisterns and aqueducts. The system must be installed after an active carbon filter, such as in water distributors, which are becoming increasingly common in cities.

There are no limits to the possible applications of UV-C rays. Even in domestic environments, they are used to prevent build-up of mould on walls, eliminate mites from bedrooms, keep room air healthy and treat water.
UV-C rays are even able to eliminate odours and fatty deposits in industrial kitchens and in the restaurant industry in general, in conjunction with the emission of ozone. LIGHT PROGRESS has also developed a specific system for this particular application (UV-SMELL).

Bacteria, viruses, spores, fungi, moulds and mites are all sensitive to and eliminated by UV-C radiation.

Each bacterium, virus, yeast, mould or mite requires a different UV-C dose to be deactivated or eliminated.
There are widely recognised documents which report these levels. Light Progress has one of these documents and uses it regularly in designing and implementing its systems. To give an approximate idea regarding the application times of UV-C rays, these can range from fractions of a second to several seconds.

Viruses, bacteria and mould, animal waste, mites and pollens are among the main causes of dangerous infections and allergies.
Each of these contaminants is dispersed in a different way: mites, spores, bacteria and mould, for example, are continuously transported by air, while other bacteria and viruses are “grouped” into solid particles, such as spores or drops of moisture, and then inhaled by humans.

In air conditioning systems, when contaminants get inside the air treatment unit (ATU) and air distribution ducts, the system, which is dark and moist, becomes a breeding ground for them to grow and multiply, making the air we breathe unsafe.

The air also contains concentrations of chemical pollutants which are dangerous if inhaled in large quantities or on a continuous basis.
Irradiating air in a central system or installing an air purifier complete with UV-C lamps and a TiOx titanium dioxide filter greatly reduces the likelihood that these pollutants (whether microbiological or physicochemical) will result in health problems that often can only be diagnosed after many years.

The legal microbiological limits for drinking water contained in Legislative Decree 31/2011 are very strict.
Methods for eliminating microorganisms from water may be chemical (chlorination) or physical (UV-C rays, heat).
In the first case, ingested water may contain harmful, chlorine-derived waste substances such as chloramines, which alter the smell and taste of the water, or other undesired by-products that are harmful to human health and to the environment such as volatile organic substances, including trihalomethanes, which are highly carcinogenic.

Heating (boiling water before use) could be helpful in preventing the above problems, but it is certainly not practical, besides creating handling problems, requiring long-term cooling.

A UV-C ray system installed close to the point of use a on water line safely removes all microorganisms, irradiating them at a dose far higher than the minimum safe dose – making it very effective – without leaving a residue. The purchase and maintenance costs of the system and its replacement parts (bulbs) are extremely low. UV-C rays also reduce the amount of chlorine and any derivatives (aqueduct) into minuscule particles that are harmless to health.

When a UV-C light is turned on, the number of microbes in the air and on all surfaces reached by the UV rays is reduced significantly. For example, in just a few minutes the bacteria Bacillus, Coli, Clostridium, Legionella, Vibrio, Salmonella, Listeria, Pseudomonas, Staphylococcus, Streptococcus, etc. can be reduced by 99% at a distance of 3 m from the device.

This enables the system to reach areas that would otherwise be unreachable with solid objects such as cleaning products and disinfectants, like hidden areas in flooring and furniture.

Where chemical disinfectants must be used, irradiating the surfaces prevents black-out areas, does not generate resistant species and can be used both day and night (without human presence), avoiding rapid re-contamination of surfaces and keeping them constantly in optimal microbiological conditions.

The efficacy of disinfection systems can easily be tested through microbiological analysis, or simply using buffers to check for the presence of microorganisms on the surfaces being tested. However, accurately verifying the quantity of microbial load found on a surface, in air or in water before and after treatment requires laboratory tests, such as HACCP.

In the case of chemical disinfectants, manufacturers indicate preventive tests under their disinfecting capacity; Light Progress has also carried out important tests at university and accredited Sinal (Accredia) laboratories. Of course, for both chemical disinfectants and UVGI technology, in order to obtain the same results as the laboratory, the product must be used according to the descriptions given in its instructions for use.

UV-C rays cannot penetrate solid bodies, unlike ionising radiation such as x-rays and gamma rays, both of which are highly dangerous to humans, even at low doses. To eliminate microorganisms using UV-C rays, they must be present on the surface of an object or transported by the air.

There are very few materials that will not block the passage of the germicidal wavelength (253.7 nm, invisible), including quartz and certain plastics such as PE or tetrafluoro-derivatives, but only if these are just a few microbes thick.
Regular window glass, polycarbonate and other transparent materials through which it is possible to see the bluish light of UV-C lights completely nullify their germicidal effect, acting as a screen.

Continuous irradiation of the eyes and skin could cause erythema and conjunctivitis, which normally clear up in a few hours. In any case, it is sensible to avoid direct, close-up exposure to sources of UV-C rays even for short periods of time. To avoid direct exposure simply cover the area to be protected using any material that is not transparent to visible light (cotton or woollen clothing or overalls) or using glass or transparent plastics (masks, helmets, glasses, etc.).

Yes. Light Progress offers two solutions in a special plastic material called Uvlon Frame and Uvlon Pipe. Uvlon Frame is made from a film which is attached to the device and collects any fragments deriving from breakage. Uvlon Pipe is a casing that is thermally applied to the UV-C tube in the factory which increases its mechanical strength (car windscreen effect) and collects and retains any broken fragments inside.

UV-C rays are similar to solar rays, but do not transmit heat. However, like solar rays, they tend have a yellowing effect on plastics that are exposed for long periods of time (especially white plastics).
