American Safe Room fabricates these steel ducts for use in underground shelters. Every shelter needs an air intake and an air exhaust duct for true ventilation.

These pipes are 4-inch diameter welded steel pipes that are primered.

They feature a pre-drilled mounting plate that mounts to the outside of your shelter – either the ceiling or the wall. There is enough pipe after the mounting plate to go through the roof or the wall and terminate flush with the inside of the shelter. The Blast Valves mount directly to the shelter wall over the ventilation pies with the included concrete wedge anchors.

The ventilation pipes can be poured in place or installed into existing 4.5 inch holes in the shelter.

Shown in the picture above is a set of ventilation pipes that are made to go through the ceiling of a shelter. Note that the tops are swept through 180 degrees and the bottoms have the mounting plates welded in place.

For more information, please see the installation and operation manual (PDF).

These ventilation ducts are built to order. Please see the manual for ordering details. Once we have the required information from you, we will send you a formal quotation.
