CO2 / CO REMOVAL AIR REGENRATIVE SYSTEMS - SCRUBBERS
Atmas offers a wide range of solutions in the field of air supply and management, air filtration, chemical, biological, radiological, and nuclear (CBRN / NBC) and toxic industrial chemicals (TIC) filtration, carbon dioxide (CO2) & carbon monoxide CO removal systems - scrubbers, oxygen (O2) supply systems, air quality monitoring and control, and more life-support systems for civil defense shelters, strategic infrastructure, industrial facilities and more.
The standalone air regenerative systems ‘scrubs’ the air inside enclosed spaces - removing harmful gases such as CO (carbon monoxide) and CO2 (carbon dioxide) - a vital requirement for any sealed environment sheltering human life for an extended period of time.
Only a shelter that is 100% sealed from the external environment, guarantees safety from the ingress of smoke and other harmful toxins.
Both CO and CO2 can become lethal in high concentrations. This valuablelife saving equipment has been designed to operate standalone in any
refuge chamber, safe haven, bomb shelter or survival shelter.
Carbon dioxide (CO2) is a colorless, odorless gas that is produced during human respiration. A typical person will produce between 24 to 30
litres of CO2 per hour (0.85 to 1.1ft3).
CO2 is a simple asphyxiate and causes adverse health effects at elevated concentrations. The United States Mine Health & Safety Administration
(MSHA) stipulates a permissible exposure limit of 1% and a ceiling limit of 2.5% for miners trapped in a coal mine. Similarly, the Occupational
Safety and Health Administration (OSHA) have set a permissible exposure limit of 0.5% over an 8-hour work day, with a ceiling exposure limit
of 3% for a 10 minute period. The symptoms of CO2 exposure are listed below.
Symptoms according to CO2 concentration:
0.03% - Normal concentration in air
0.5% - Lung ventilation increases by 5%
1% - Symptoms may begin to occur
2-3% - Symptoms of simple asphyxia occur
5-10% - Prolonged exposure could result in unconsciousness and death
>10% - Unconsciousness in less than 1 minute, leading to death
Carbon monoxide (CO) is an asphyxiate that is endogenously produced by humans at varying levels depending on different health factors
(i.e. smokers, obesity, hypertension, anemia, age). CO exposure exerts its main toxic effect via its ability to interfere with organs that have
a high metabolic demand for oxygen (O2).
The Occupational Safety and Health Association (OSHA) specifies that the carbon monoxide content of the atmosphere in a room, building,
vehicle, railcar or any enclosed space shall be maintained at not more than 50 parts per million (ppm) for an eight hour period.
