|
To pressurize, store and deliver HP air to various ship loads
|
HP Air
|
|
|
Ambient air in the ship is compressed to 4500 psi via a 4 stage compressor
|
HPAC
|
|
|
Remove LARGE amounts of oil and water vapor from the compressed air
|
Moisture Separator
|
|
|
Remove remaining oil and dirt by passing the compressed air through a paper-like filter
|
CUNO Filter
|
|
|
Temperature of air passing through Cuno filter and Moisture Separator
|
180 degrees
|
|
|
uses a drying agent called desiccant to remove the remaining moisture from the air
|
Dehydration towers
|
|
|
Airbanks 1,2,4 & 5
|
Used for Emergency Blow system
|
|
|
where is HP air stored
|
Airbanks (airflask) located in the main ballast tanks
|
|
|
Airbank #3
|
used for ships loads
|
|
|
Takes in higher air pressure and reduces it to a lower pressure
|
Reducing Manifold
|
|
|
To pressurize, store and distribute low pressure air to various ships loads( name of system)
|
Service air system- below 700 psi
|
|
|
Major air header source of air
|
supplied from airbank #3 via reducing manifold
|
|
|
takes ambient air on the ship and compresses it to 125 psi- normal supply to the 125 psi air header
|
LPAC
|
|
|
removes water from the service air prior to is introduction into the distribution manifold
|
LPAD low pressure air dryer
|
|
|
supplies ships loads that require air pressure between 21-125 psi
|
125 psi header
|
|
|
EX: 125 header (5)
|
potable water, FWD trim, hydraulic vent & supply tanks, EAB air
|

|
supplies ships loads that require air pressure below 20psi
|
20 psi header
|
|
|
EX: 20psi header
|
battery agitation, sonar sphere access
