Strong Pre-engineered
The Shelter Systems are constructed pre-engineered, providing you the
peace of mind of knowing that your shelter will protect you no matter
what.
The Shelter Systems uses a unique, patented technique to ensure that each
shelter can withstand a three-bar blast.
Innovative Construction using the following components :

New style - with removable rain hood and insect screen
above
Old style - with 180 degree rain hood
These steel ventilation pipes 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 shipped with a
primer finish.
They feature a pre-drilled mounting plate that mounts to the outside of
your shelter - either the ceiling or the wall. The Blast Valves mount directly
to the shelter wall over the ventilation pipes with the included concrete
wedge anchors.
The ventilation pipes can be poured in place or installed after the concrete
has cured with the included concrete wedge anchors and heavy duty
neoprene gasket.
Shown in the picture to the left is a set of old style 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.
Note that we have updated this design - we now terminate the top of the
pipes with a heavy duty removable steel rain hood that houses a removable
(and cleanable) insect screen. They also appear to be "stanchions" not
"battleship air scoops" in order to minimize the possibility of someone
spotting the location of your underground shelter.
These ventilation ducts are built to order. Once we have the required
information from you, we will send you a formal quotation.
