Nuclear Biological Chemical Doors

Nuclear Biological Chemical Doors for NBC Rooms


Nuclear, Biological, Chemical Vault Doors

12" N-B-C DOOR

Our American made NBC Vault Doors secure safe rooms domestically and around the world. Our 12" thick NBC vault doors are manufactured with triple-tiered steel construction, U-Shaped blast resistors and Jig-Saw five point sealing doors. Where many NBC vault doors have simple locking systems, we have S & G group I locks, 18 locking bolts and 1" thick 60 Rockwell hard plate. This allows your NBC room to also be used as a walk-in vault.

Sportsman and Pentagon Vault Doors travel north America personally installing and constructing our NBC Rooms and Blast-Resistant Doors. Our Hi-Tech mobile trucks come to your residence or business for FULL SERVICE. Our NBC Shelters usually cost $150 - $200.00 a SQ FT. With air filtration systems, water purification pumps, tech values and a comfortable living space. We can build special "step system hatch doors" with secondary entrances and "hidden passages". Our Safety Shelters are much like underground homes with kitchens, bathrooms, closets, bedrooms with your choice of carpet, tile, sheet rock walls, painted or textured.

Our new blast hatches now come with N·B·C resistance. What's unique about our NBC Hatch Doors? They come with vault-level security. Most hatch doors are easy to break into. With an internal release, exiting your vault room during emergency is easy. Simple lift your internal spring-loaded handle and pull it toward the middle of the door. And the fire levels are extraordinary. With a concrete-filled 6" blast carriage door, not only is your blast door 2-Hour fire-rated, but it also comes with a blast rating not available on most N·B·C products.

Your hatch vault can be ordered with our NEW Porcupine reinforcement System (12 - 1" thick - 5" long steel posts continuously welded to your frame so your vault can be directly tied to the rebar in your concrete-filled walls).

NBC Doors for Storm Shelters and Safe Rooms



NBC Filtration SystemPentagon blast resistant Vault Doors are utilized in civil defense and military shelters. Different levels of armor-plated doors, stainless steel doors, armor-plated covers and pressure doors are available. These doors are designed for high and medium levels of protection. Pentagon Doors can have concrete added to it's double steel 8" thick door upon installation OR our manufacturing technicians can add the concrete into our doors to insure optimum bond levels.

When properly installed, Pentagon Doors can offer protection against chemical agents and radioactive fallout. Rooms will requires ventilation units, which are equipped with valves, pre-filters and NBC filters. NBC ventilation units create "over-pressure" inside the shelter, preventing harmful gases from leaking inside.

NBC-filters are shockproof units designed to clean the air of the following contaminants:
* Nuclear fallout * Radioactive Materials & dust * Biological agents * All known war gases

Pentagon's NBC Doors are installed in hardened industrial, private and military shelters. NBC filters must be installed in these rooms with nominal airflow capacity. A wide range of ventilation and filtering units for shelters can be connected by flexible hoses in order to clean the air of radioactive dust, bacterium and all known war gases.
