Description of Operation (continued) | Cooling System (not shown): This | |
Outlet Pressure Gauge: The | compressor contains an advanced | |
outlet pressure gauge indicates the | design cooling system. At the heart of | |
this cooling system is an engineered | ||
air pressure available at the outlet | ||
fan. It is perfectly normal for this fan | ||
side of the regulator. This pressure | ||
to blow air through the vent holes in | ||
is controlled by the regulator and is | ||
large amounts. You know that the | ||
always less than or equal to the tank | ||
cooling system is working when air is | ||
