Building a bomb shelter? We have everything you need right here.
American Safe Room manufactures all of the critical components for underground bunkers as well as complete bomb shelters: NBC filters, blast doors, ballistic doors, blast hatches, blast valves, ventilation pipes, and other bunker accessories.
Scroll down to see all of these components and be sure to see our new videos on installing a Safe Cell and installing a single leaf blast door. These components were installed in a missile silo in Texas.
We provide free air filtration and component blast protection consultations. If you are planning on building a shelter, contact us.
NBC air filtration equipment
The Safe Cell line of nuclear, biological, and chemical air filtration systems feature two backup systems: an optional hand pump and an integrated battery backup capability.
The Safe Cell is designed to meet the critical specifications laid out by the US Army Corps of Engineers.
Using lightweight plastic housings, the Safe Cell has a unique protocol for safely changing the filters so you can stay securely buttoned up in your shelter for extended periods of time. A nuclear grade HEPA filter and ASZM TEDA carbon give military grade air filtration and require that the Safe Cell only be shipped to US addresses because this air filtration system has been determined to be a class IV munition by the US State Department's Directorate of Defense Trade Controls.
The Safe Cell comes in two sizes (60 and 120 CFM), two power options (AC with DC backup and DC only), and is sold individually or bundled with all the accessories (complete systems):
60 CFM AC/DC Safe Cell
60 CFM AC/DC complete blast protected NBC system
120 CFM AC/DC Safe Cell
120 CFM AC/DC complete blast protected NBC system
60 CFM DC only Safe Cell

Blast doors, ballistic doors, and blast hatches
We fabricate these engineer-certified blast doors, blast hatches, and ballistic doors. The blast doors and hatches are rated for a minimum of 3.4 bar (50 PSI) and go up from there to whatever blast and rebound load rating is required.
Standard and custom sizes are available with many options like viewers, assault resistant cam latches, differential pressure gauges, and wide angle viewers.
We have designed and fabricated many custom blast doors for industrial applications such as foundries, chemical plants, high pressure valve test cells, and munition magazines.
These blast doors feature a concrete filled steel envelope door leaf and either a bolt-on or pour-in-place frame. We form the door skins on a press to ensure they are straight and will uniformly compress the door seal, ensuring a tight shelter that will hold overpressure and keep out airborne toxins.
The hatches feature a deadbolt lock, an internal cam latch, a seal that is compressed between the blast lid and the frame, and lift struts to assist opening.

Blast valves, overpressure valves, and ventilation pipes
We manufacture all the equipment you need for air ventilation and filtration. These components are designed to fit and function together to protect your shelter from airborne toxins, radioactive fallout, and blast effects from detonations.
Our double acting poppet style blast valves are rated for 7 bar (101 PSI). They are a heavy steel pressure vessel that allow low pressure air to move in either direction through them, but automatically close when hit with high pressure or negative pressure.
Our overpressure valves are one way check valves that do not allow toxins to backflow into your shelter through the outflow vent pipe. They also give a slight back pressure to the airflow to help the Safe Cell create and maintain positive relative pressure (overpressure).
