This
overpressure relief valve is a one-way check valve that
installs on the outflow of your shelter. It can be attached
directly to the blast
valve or right on the inside wall if blast valves are
not used.
It
is critical to creating an overpressure in the protected
space by metering the flow of the air. 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.

more information, please see the manual
