TO IDENTIFY THE AIR In China and most other Asian countries, particulate matter (PM) in the air is 20 times more than that in Ger many and other Wester n European countries. In some places, it is even 100 times more. We can tell the difference from the air transparency or from a PM detector. What are the consequences ? We increased the workload of our lungs by 20 times +; in other words, the amount of PM inhaled by a 5-year old child equals that of an adult through his entire life.

PARTICULATE MATTER(PM) PER LITER IN THE AIR

Air in Western Europe

This is why there are more and more people who suffer from respiratory system diseases and various kinds of cancers in hospitals year by year. Perhaps we are unable to control the exhaust produced by power plants and vehicles for the time being, yet can we control the air coming inside our rooms? BROAD Fresh Air Machines offer this possibility. Air in Asia

FEATURES OF BROAD FRESH AIR MACHINE Super air purif ication With 3-stage air purif ication, it can reach 99.8% air purification efficiency. Energy saving

With heat exchange between fresh air and exhaust air, indoor temperature loss due to ventilation can be reduced by 70% ~ 90%.

Electricity saving

Low-resistance f ilter, high-eff iciency fan and inverter control can save power more than 40% than that of regular ones.

Low cost

Fresh air purif ication can reach the level of clean rooms such as hospital operation rooms and chip workshops, whereas the price is only 15% ~ 30% of that for a current one.

Unique

From system structure to air purif ication technology and heat exchange technology, they are all originally invented by BROAD — the only one in the world.

Operation electricity consumption: 0.3~0.9W/m3 (inverter controlled) 4. Voltage: small units 220V, medium and large units 380V 5. Optional functions: AC, Humidification, Dehumidif ication

THE STRIKING EFFECT AFTER USING BROAD FRESH AIR MACHINES - Getting up in the morning, you feel extremely comfortable (no bitterness in the mouth or dryness in the throat). - After using it for several months, your health gets improved in all aspects, such as better sleep and less inf luenza. - For people who suffer from respiratory system diseases, symptoms are promptly eased. - You see no dust at all on table tops and floors even after half a month; sheets can no longer easily become dirty. - Rooms are f illed with fresh air, no more paint smell in new houses, no smell after cigarette smoking.

THE PARADOX OF WATER AND AIR Many people have been drinking purif ied water, but consider that breathing clean air in a long time will degrade human immunity. This is definitely a paradox. The evolutionary process of human life is essentially the process of pollutant biological accumulation. The less pollutant accumulated in the air, water, food, medicine, and cosmetics during his entire life, the less diseases he gets and the slower the aging process becomes.

THE PARADOX OF MEDICINE AND AIR It is another paradox that people are generous with money on medicine, but not on air. For the World Health Organization has certif ied that 68% human diseases are related to indoor air pollution.

MODEL SELECTION & INSTALLATION

Conference Hall

Reception Room

- Installation type: Can connect to air duct, or blow directly. - The distance between fresh air inlet and exhaust air outlet should be as far as possible, so it can make the fresh air cover more room areas and save more energy. - Do model selection according to the air circulation cross section rather than the simple area only: ventilation rate is 10~20 times/hour. - For example, an 80m2 residence with a sitting room 2.7m high and 4m wide has the air circulation cross section at 11m2. Fresh air blows from one end of the sitting room, through the bedroom, and then vented from the toilet. Then a model SC125 or SC250 is suitable for this residence. - Another example, an 800m2 open office area with a dimension of 50m x 16m x 2.8m, has the air circulation cross section at 45m2. Fresh air blows from the top of the office area, through the entire office, and then vented from the toilet in the far end. Then a model SD500 or SD1000 is suitable for this area. If the office density is high, exhaling a great amount of CO2, models like SD1500, SD3000 are preferred. - Rooms should be airtight, while ventilation is done by Fresh Air Machine.

AIR DETECTION After installation, BROAD Fresh Air Machine must be detected with instrument on the spot — It is qualified only when the blown air is 500 times cleaner than outdoor air (Picture above is BROAD air detector; other professional instruments can also be used).

BROAD Fresh Air Machines have obtained international certif ication of European CE, American ETL and so on.

TO FURTHER IDENTIFY THE AIR - μm means milli mm, particles≤10μm are called inhalable PM, which can pass through the respiratory system of nose and throat, and enter into the lungs. - Particles≤2.5μm can pass directly through the alveolus in the lungs into the blood stream. The smallest human cell is approximately 2.5 micron across. - Particles≤2.5μm are extremely light and can f loat around more than 300km. Therefore, there is not much difference between urban and rural areas. - In general, more than 90% of particles≤2.5μm in the air come from the exhaust air produced by power plants, factories and vehicles, which contain heavy metal particles, such as mercury, cadmium, and lead. All of them are serious carcinogens and are more harmful than cigarettes.
