The ASR-200-AV-NBC Safe Cell is a portable, positive pressure, emergency air filtration system is
designed to offer protection in the event of a nuclear, biological, or chemical event when installed
in a protected space (a shelter or room). When properly installed, this system is capable of giving
adequate supply of filtered air for up to 24 occupants, according to ASHRAE standard 62* and 34
occupants according to Israeli standards.
*cited in the US Army Corps of Engineers Technical Letter number 1110-3-498 Design of Collective
Protection Shelters to Resist Chemical, Biological, and Radiological (CBR) Agents,
paragraph C-9b (3).
The system works by drawing outside air through its bank of four filters and introducing it into the
protected space creating a slight overpressure (positive pressure). This overpressure is designed to
deny access to any unfiltered air that would migrate back into the shelter area through small
openings such as cracks or electrical outlets and conduit.
This overpressure relieves the occupants from wearing gas masks and protective clothing,
enabling them a safe and comfortable environment.
The system operates from any standard 110-240 volt AC, 50/60 hertz power source.
In the event of a line power failure the unit has two emergency backup systems:
The first backup is an automatic switching power supply that trickle charges a user-supplied
battery and then automatically draws power from that battery in the event of a power outage. In
other words, if you were to "pull the plug" the blower will continue to operate and maintain an
overpressure in your protected space. When the electricity comes back on line, it will automatically
revert to drawing from the AC power and recharging the battery.
The second backup is an optional manual (hand pumped) blower that can be used in the event of a
long-term power outage.
