BIOMARINE BIOPAK 45
-
The BioPak 45 (figures 1-2) is a compressed-O2,
closedcircuit
-
apparatus with a disposable CO2-absorbent canister. It
-
was certified by the National Institute for Occupational Safety
-
and Health (NIOSH) in 1973 as a 45-min unit when the
-
O2 cylinder is filled to 2,100 psi (at room temperature). The O2
-
is delivered to the user at a rate of 3.6 L/min at ATPD (ambient
-
temperature and pressure, dry) with no demand valve. The CO2
-
absorbent is a form of soda lime (mostly calcium hydroxide).
-
Unlike most of the other apparatus tested, the BioPak 45 is
-
worn on the chest rather than the back. The face mask is
-
equipped with a speaking diaphragm. The low-pressure alarm
-
sounds at approximately 25% of capacity.
-
Exhaled air travels past the exhalation check valve in the
-
face mask, through the exhalation hose, through the CO2-
-
absorbent canister, and into the breathing bag. Air is inhaled
-
from the bag, through the inhalation breathing hose, past the
-
inhalation check valve, and into the face mask.
There is an
-
optional coolant ring that surrounds the CO2-absorbent canister.
