A shelter is only as good as its air filtration system. This Air Filter System is a Nuclear, Biological, and Chemical (NBC) air filter that will enable you to create either a positive pressure safe room, fallout shelter, bomb shelter or a negative pressure isolation room. It will operate on regular 110v line power or will automatically switch to battery backup. In case of power outage and if no battery is available consider adding the optional hand powered manual bellows or the Hand Crank Airpump.
This will give you 3 ways to operate your air filter system.
This system will handle up to 12 Adults. IN 235 CFM Fresh Air, OUT 60 CFM Filtered air.
This Air Filter System can be mounted in a residential safe room with both backup systems in place: a user supplied battery for short term power outages & the hand operated bellows for longer power outages. The air is drawn through the flex hose, into the bottom end bell, then through the filter bank in the middle and out the top end bell to overpressure the shelter or safe room.
Everything shown above is included with this package: One ASR-100-AV-NBC Safe Cell with Bypass Port and Battery Backup capability that has a pre-filter set, a nuclear grade HEPA, a war gas carbon adsorber, a wall mount bracket, air intake hose, and a hose wall flange.
The Budget Unit does not come with Blast Valves or Over Pressure Valves or Manual Airpumps.
