In replying to the many hundreds of people desiring more information, we have developed some text that includes a discussion of some the specifications that we meet. Here are two of them:
Discussion number one
There are two basic engineering requirements to filtering air in a nuclear biological, and chemical Collective Protection Shelter. First is the proper air overpressure in the room relative to the outside air pressure to insure that no toxins migrate into the room through the cracks. Second is the proper filtration unit to insure that toxic agents are removed from the incoming airstream.
To insure the satisfactory performance of our system we adhered to the critical specifications of the Design Of Collective Protection Shelters To Resist Chemical, Biological and Radiological (CBR) Agents, Us Army Corps of Engineers ELT 1110-3-498 24 Feb. 1999. The only variant from the specifications is due to the fact that the Safe Cell is designed for use in a room of approximately 1500 ft/3 with an air output of 120-74 cfm offering an overpressure of 0.04-0.02 in/wg. The military version described in the specifications is for a much larger area than 1500 ft/3 with an air output of 600 cfm but still offering only an overpressure of 0.02 in/wg.
By Israeli standards the ASR-100-NBC Safe Cell System will offer life support air supply for up to 17 persons in a closed shelter. HEPA specifications:
1. Media: Water repellent glass micro fibre 99.97% True HEPA cell type (A).
2. Cell side material: Fire retardant particleboard.
3. Separators: Aluminum.
4. Bond: Polyurethane foam.
5 Gasket materials: Neoprene (RE43E1).
6 Gasket location: Both sides.
7. Factory test: Certified 99.97% (DOP).
8. UL 586 label: Required.
HEPA filter cell: Was developed by the Atomic Energy Commission and is used today in nuclear power stations, hospitals and bio-containment laboratories. HEPA Guaranteed Performance Documentation: Each HEPA filter is individually tested before it leaves the factory, your assurance that it meets rated efficiency.

The HEPA is challenged with 0.3 micrometer particles of dioctyl-phthalate (DOP).

UL also subjects the HEPA filter cell to a spot flame test of (954 deg/C). Carbon war gas adsorber specifications: NUK-TK TEDA nuclear grade coconut shell blended carbon 5.4 kg. Activity for CCL (ASTM D-3467) Moisture content (ASTM D-2867) Hardness (ASTM D-3802) Bulk density (ASTM D-2854) Ash content (ASTM D-2866) pH aqueous ext. (ASTM D-3838) Impregnate 2.1% Potassium iodide 3.1% TEDA Radioiodine removal efficiency ASTM D-3803 War gases: Hydrogen cyanide, Phosgene, Mustard gas, Sarin, Racin, VX.
Blower specifications: The blower module including all electrical circuitry is self contained. The blower module employs a quick change coupling system allowing the module to be changed on the filtration unit in about 10 seconds. This feature is to accommodate different electrical supply voltages such as a battery back-up. 110 volt AC 60 hertz 1.6 amp 250 cfm. 220 volt AC 50 hertz 0.3 amp 200 cfm. 12 volt DC 11.5 amp at 250 cfm. System air output: 102 m3/hr at 1.5 SP 1.50 inch/wc
Discussion number two
The SR-100-NBC Safe Cell is a portable positive pressure emergency air filtration system designed to offer protection in the event of a nuclear, biological or chemical attack.
The ASR-100-NBC has an air output of 120 cfm when configured for nuclear and biological protection and 60 cfm configured for full NBC protection with the gas adsorber installed. This is sufficient air supply for 12 persons, assuming the lower air output of 60 cfm and the higher of the two ASHARE requirements of 5 cfm per person as sited below in the FUNDAMENTALS ASHRAE standard.
The system works by drawing outside air through its filter banks and introducing it into the shelter area creating a slight overpressure. This overpressure is to keep any unfiltered air from migrating back into the shelter area through the cracks. The shelter must have an exhaust vent on an opposite wall of the intake vent so that air change can take place and Co2 build up does not become a problem. The desired overpressure is .02 in/wg and may be measured with the air flow meter provided with our test kit.
The ASR-100-NBC unit was designed for use in a shelter area of about 1500 Ft/3 but can be used in larger shelters providing that the airflow and overpressure requirements are meet. Because the amount of overpressure in the shelter and airflow rates produced by the unit are a direct function of the shelter construction or room tightness and is beyond our control, we make no claims as to its suitability in any particular installation other than the output a airflow of the unit itself. In order to insure sufficient airflow rate and overpressure state in a particular installation the guidelines specified in the SR-100-NBC installation manual and test kit instructions must be followed.
For added safety we recommend the adherence to local building code as well as the installation of a good Co2 monitor/alarm. ASHRAE HANDBOOK 1985 FUNDAMENTALS VOLUME Section IV Load and Energy Calculations Ch. 22 Ventilation and Infiltration (TC 4.3, Ventilation Requirements and Infiltration) Page 22.1
Minimum Outdoor Air Supply Rates: ASHARE Ventilation Standard 62-1981,1 defines minimum outdoor air supply rates for various types of occupancy. These rates have been arrived at through a consensus of experts working in the field. A minimum rate of 5 cfm per person for sedentary activity and normal diet holds the Co2 level in a space 0.25% under steady state conditions. While normal healthy people tolerate 0.5% Co2 without undesirable symptoms and nuclear submarines sometimes operate with 1% Co2 in the atmosphere, a level of 0.25% provides a safety factor for increased activity, unusual occupancy load or reduced ventilation. ASHRAE HANDBOOK 1982 APPLICATIONS Environmental Control for Survival 11.1-11.24 Page 11.4 Vitiation Factors: Carbon dioxide concentration should not exceed 3% by volume and preferably should be maintained below 0.5%. For a sedentary man, 3 cfm (1.4 l/s) per person of fresh air will maintain a Co2 concentration of 0.5%.
