Ballistic sliding bomb shelter door

Ventilation pipes
Heavy steel, blast resistant
Easy bolt on installation

Steel ventilation pipesAmerican Safe Room fabricates these steel ventilation pipes for use in underground shelters. They are usually installed in pairs on a shelter for air intake and air outflow.

They can mount on to the roof or wall of an underground shelter.

Included are heavy duty gaskets and concrete wedge anchors for easy, bolt on installation after your shelter pour has cured.

These pipes are 4 inch inner diameter welded steel pipes that are finished with a coat of primer. They feature continuous welded construction including a mounting plate that mounts to the outside of your shelter with the included concrete wedge anchors. They can mount to either the ceiling, or the wall of a shelter. Also included is a heavy neoprene gasket that seals the mounting flange to the shelter.

Ventilation pipes for wall penetrationTwo pipes made to be mounted on a shelter wall. The mounting flanges bolt onto the wall over the penetration pipe that is poured in place between the forms.

The top of these pipes feature a heavy duty removable steel rain hood that houses a removable (and cleanable) insect screen. We changed to this design after building vent pipes with 180 degree tops because they appear to be "stanchions" not "battleship air scoops" in order to minimize the possibility of someone spotting the location of your underground shelter. A steel post may get a second glance, a large steel candy cane in the back yard warrants a closer inspection.
