Security Pod (Urban Foxhole)
One Foxhole that is ten feet two and a quarter inch diameter reinforced hull with fifteen inches of entrance tube. The Security Pod has a specially designed hull able to withstand extreme pressure and be water proof and chemical resistant. The security pod comes in 2 pieces that can fit one piece at a a time through most garage doors. The system is bonded and bolted at the flange connection by the installer on sight. The Security Pod comes with a built in floor system proximately 26 inches off of the bottom of the pod. The floor system comes with access ports for storage. Included with the Security Pod are all bolts and adhesives necessary for installation. Hardware for securing chain ladder to the floor.
$21,500 US Dollars plus applicable taxes and shipping costs
Junction Box and Hatch
These two components can be purchased separately. The standard junction box and hatch are shown above and come welded together. The bottom of the junction box has a hole cut into it to accommodate the entrance tube. To see the thirty six inch rough opening hatch specifications please see “Hatch” in the main menu. The junction box comes with a welded entrance ladder deep enough to penetrate the Security Pod approximately one foot when purchased with the hull section. The remainder of the ladder supplied is chain link and wood runners. (this allows the ladder to be rolled up once every one is inside) The junction box also comes with a jack support brace to force the hatch open from the inside if any debris is lying on the hatch. ( Note: The junction box shown above has a hatch welded to it. The junction box is 2×2 inch tube framing with 16 gauge sheet metal. Box dimensions are 78 inches by 28 inches by 53 inches)
$10,900 US dollars plus applicable taxes and shipping costs
The junction box can be purchased separately with no hatch and no ladder in case the owner would like to supply their own. ($3,500)
The ASR-100-AV-NBCBP Air System “Safe Cell”
The Safe Cell is a portable, positive pressure emergency air filtration system designed to overpressure protected spaces such as bomb shelters,military vehicles, and safe rooms to provide collective protection during and after a nuclear, biological, or chemical event.
It features a filter bank that is designed to protect against all known airborne toxins including nuclear fallout, radioactive iodine, weaponized biological carcinogens, and warfare gases such as sarin, VX, and tabun.
The entire system has been designed to meet the critical requirements in the United States Army Corps of Engineers Technical Letter ETL 1110-3-498.
This air system comes with the 120 volt ac / 12 volt dc system. It also contains a battery charger for the automatic trickle charge for the 12 volt dc back up system. Included with the air system is a mounting stand.
$2,900 US dollars plus applicable taxes and shipping costs
Emergency back up hand air pump
This hand operated bellows slip-fits instantly into the top of the Safe Cell and is operated by pumping it up and down. It is used to draw filtered air into a protected space during a long term power outage.
A typical shelter occupant cannot physically maintain an overpressure with this device (truth in advertising), but you can draw in air through the filter bank and into your shelter, displacing the carbon dioxide that is exhaled by the occupants ~and~ you still have safe, breathable air being filtered for NBC toxins.
The constraint for maintaining an overpressure in any decent sized shelter (larger than a coat closet) is human endurance – there is simply too much air to move, either by a plunger system (which we have), or a rotary crank system, to maintain an overpressure for more than a few minutes. Either way, the oxygen that you consume and the carbon dioxide that you exhale while you bring in filtered air by hand power is beyond what humans can accomplish.
Our emergency backup bellows has an output of 50 cubic meters (1766 cubic feet) per hour at 50 strokes per minute using a 7 inch stroke and an output of 100 cubic meters (3200 cubic feet) per hour at 50 strokes per minute using a 14 inch stroke.

Double-acting automatic 7 Bar
Blast valves are mounted on the air intake and air outflow pipes inside a bomb shelter. As a high pressure wave from a nearby detonation passes over the shelter, the pressure travels down the pipes and into the shelter. If this high pressure is not stopped, it will destroy the air filtration equipment and injure or kill the occupants. Directly behind this high pressure wave is a vacuum wave – all of the atmosphere is blown outward from the epicenter of the detonation. This vacuum wave can be as deadly as the pressure wave. That is why these valves are double acting – pressure and vacuum.
The ARS-101-BV automatic double- acting blast valve automatically and near instantly closes when the initial positive pressure wave from an explosion hits and automatically closes a second time (in the other direction) when the outside air pressure goes negative (a vacuum) in relationship to the internal shelter pressure. When the outside air pressure returns to normal, the blast valve automatically returns to its normally open state. In other words, it lets air flow into your Safe Cell and out of your exhaust port for normal operation, but will not allow a blast of high-pressure air to enter your shelter – and bring contaminants with it.
This blast valve is designed and tested to protect an underground shelter from a 100 pound per square inch detonation.
In order to withstand this pressure, these blast valves are fabricated from ASTM grade A steel. This is a heavy, robust item designed to keep the massive pressures of a nearby conventional or nuclear blast from injuring or killing the occupants of your bomb shelter.
We have a new lock down feature that allows you to lock the valve in the closed position. If you have a structural fire above your shelter or a malicious person dumping water or smoke down your vent pipes, you can remove the air intake hose or overpressure valve lock the valve shut.
These valves are only necessary in hardened bomb shelters and should be used in pairs – one on the air intake pipe and one on the air outflow pipe. They install on the inside wall of an underground blast resistant shelter right over the air intake and outflow ventilation pipes. Included are a heavy duty 1/4″ neoprene gasket, concrete wedge anchors, and a masonry bit for the anchors.
The air intake blast valve has the air intake hose from the Safe Cell slipped onto it, the air outflow blast valve has the overpressure valve slipped onto it. The airflow is:
- Down the intake ventilation pipe
- Through the wall or ceiling
- Through the blast valve
- Through the air intake hose
- Through the NBC filter bank
- Out of the Safe Cell
- Throughout the shelter
- Through the overpressure valve
- Through the outflow blast valve
- Up through the outflow vent pipe
True ventilation requires air in and air out. You control where the air enters and where it leaves – every bit of it being filtered by the Safe Cell.
$600 US dollars each (includes one flange) plus applicable taxes and shipping costs
Over pressure valve
The overpressure relief valve is critical to creating an overpressure in the protected space by adding the proper, metered resistance to the outgoing airflow. The valve is normally closed and will not open unless the air pressure inside the shelter is slightly greater than the outside air pressure.
This gives you true ventilation – air in through the Safe Cell and out through this valve preventing the buildup of carbon dioxide exhaled by the occupants. Carbon dioxide poisoning will incapacitate and kill the occupants of an enclosed space without ventilation long before oxygen deprivation.
Please specify at time of ordering whether or not you are mounting this valve directly on the wall or ceiling – or if you are going mount it to the blast valve We will configure your overpressure relief valve so it either has a mounting flange for the wall or ceiling or a slip-fit connection for the blast valve.
A good rule of thumb is that if you are underground, you need blast valves and if you are above ground, you do not – unless you have a hardened structure above ground. There is not much need for blast valves unless you have a hardened, blast resistant structure.
Any protected space will benefit from this valve, especially if it is well sealed, then this overpressure relief valve is a necessity – if you want true ventilation.
