the air tank and is used to drain condensation at the end of
each use.
Check Valve : When the air compressor is operating,
9
the check valve is "open", allowing compressed air to enter
the air tank. When the air compressor reaches "cut-out"
pressure, the check valve "closes", allowing air pressure to
remain inside the air tank.
