MK-16 Component Systems Flashcards
What is the function of the housing system?
Maintains low-mu
Streamlines the rig
If lost, dive must be aborted.
What is the Recirculation system’s function?
Removes CO2 from exhaled breathing gasses
What are the support screens for?
Allow proper gas circulation between moisture absorbent pad and canister.
What is the function of the moisture absorbent pads?
Absorbs the moisture in the exhaled breathing gases.
What is the function of the hydrophobic filter?
Retards moisture and disperses gas for an even flow through absorbent
What is the purpose of the compression pad?
Evenly distributes pressure on absorbent.
What are the two types of CO2 absorbent?
High performance sodasorb (4-8 mesh)
Sofnolime (8-12 mesh and 4-8)
True or false, The use of IND (indicating) CO2 absorbent material is NOT authorized for the MK 16.
True
What are the three causes for failure of the CO2 absorbent material?
Channeling of exhaled gas is due to an improperly packed canister.
Water intrusion into scrubber causing CO2 absorbent to become saturated and fail.
Exceeding canister duration limits.
