Building a safe room or bomb shelter?
We have everything you need right here
American Safe Room designs and manufactures all of the critical components you need to construct a Nuclear, Biological, and Chemical resistant safe room. Since 2001 we have sold thousands of Safe Cells NBC air filtration systems for use in underground bunkers, safe rooms, nuclear power plants, chemical plants, and other industrial applications – see who uses the Safe Cell here.
We also manufacture equipment for underground shelters like blast doors and hatches, blast valves, and steel ventilation pipes as well as a complete underground shelter kit.
The Safe Cell
NBC Air Filtration System
The Safe Cell is a self contained NBC air filter that has been designed to meet the critical specifications laid out by the US Army Corps of Engineers. It features an on-board automatic battery backup system that instantly draws from a user supplied battery if the grid goes down. Once the grid is back up, it automatically switches back to AC power and recharges the battery. No other NBC filter sold in America has this integrated automatic backup system. If the grid stays down and your battery runs out, the optional backup hand pump or the backup hand crank can be used to bring filtered air into your shelter and expel the carbon dioxide and moisture that the occupants exhale.
Easy installation and reliable operation
Thousands of people have installed Safe Cells in their homes and underground shelters. We ship them in nondescript boxes by UPS Ground. Each box has a carton contents label on the inside flap that lists everything in the box and every item in the box is clearly labeled. Box number two will have hard copies of the manuals for all of the parts you ordered. These manuals have step by step instructions for assembly, installation, and operation.
Know that your shelter is protected from airborne threats
Every bunker built by a government that we know of uses an NBC filter designed to keep the shelter in positive relative pressure (overpressure). The reason for this overpressure is so that you are not relying upon how well your protected space is sealed up. If there are any minor leaks, the air flows outward, keeping out all airborne toxins. The Corps of Engineers considers an overpressure of 0.3 inches of water gauge a Class 1 protected space. The Safe Cell puts out about three times this amount of pressure and if you do not have any major leaks in your shelter, you will stay above this specification.
Complete protection from nuclear, biological, or chemical threats
The Safe Cell is designed to draw air in through a chemical resistant air intake hose into the bottom end bell that has been designed to diffuse the airflow and hit the entire surface of the pre-filters evenly. After the air goes through the pre-filters it is next drawn through the nuclear grade HEPA filter. This HEPA filter is individually tested (not batch tested) and the results of that test are on a placard right on the filter. Next in line is the carbon adsorber. We use a blend of NUK-TK carbon (optimized for radioactive iodine – a true gas) and ASZM TEDA carbon (optimized for the higher volatility warfare gases). The ASZM TEDA carbon is what the US military uses in their gas masks and collective protection filters and is cannot be shipped outside of the United States without an export license.
Made in America, we have them in stock for immediate shipment. They come in two sizes rated by air output – 60 cubic feet per minute (CFM) and 120 CFM. According to the US Army Corps of Engineers, each occupant needs five CFM, so the two Safe Cell models will allow for 12 and 24 occupants, respectively. If you anticipate more than that, more than one filter can be installed.
There are critical features that are only found on the Safe Cell. You can’t find them in any other filtration system. The Safe Cell also features an impressive collection of government and industrial users.
