About 4Survival a Subsidiary of Earthlog Equity Group ®
Welcome to our web site Earthlog Equity Group 4Survival ®
and thank you for taking the time to learn more about our firm.
Since 1989, we at Earthlog Equity Group ® have been selling Earth
Sheltered Homes, Log Homes and Building materials.
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 :
The Adjustable Overpressure Valve is critical to creating an overpressure
in the protected space by adding the proper resistance to the outflowing
air. This valve is normally closed and will not open unless the air pressure
inside the shelter reaches the opening pressure set by the adjustment cap.
When used with an ASR-100-AV-NBC Safe Cell, the adjustment range is
zero to 1.75 inches of water column.
The adjustment cap is located at the bottom of the valve assembly.
Tightening this cap increases the pressure in the protected space. This
allows you to compensate for a shelter that is not entirely sealed up -
within reason. This valve should be used with the Differential Pressure
Gauge.
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.
This valve can be installed onto a blast valve. A good rule of thumb is that
if you are underground, you need blast valves and if you are above
ground, you do not - unless you have a hardened structure above ground.
There is not much need for blast valves unless you have a blast resistant
shelter.
Any protected space will benefit from this valve, especially if it is well
sealed, then this overpressure relief valve is a necessity.
