TM 55-1930-209-14&P-7 Table 1-1.  Compressed Air System Major Components (continued) Component Location and Function Air Station 8 Workshop port bulkhead In air supply line beyond air Seawater Seachest pressure regulator 1 with air pressure gauge.  Controls air for Blowdown Valve blowdown  of  seachest  In  void  2  port.    Used  In  conjunction  with   seawater  valve SW30. Air Station 9 ROWPU space aft bulkhead In air supply line beyond air Generator Cooling pressure regulator 2 with air pressure gauge.  Controls air for Seachest Blowdown blowdown of seachest In void 4 port.  Used In conjunction with Valve seawater valve SW44. Airhose, 50 Feet Attached to air stations.  Provides air pressure from air stations Self-Retracting to pneumatic equipment. Airhose, 25 Feet Dedicated hose used only for providing air pressure to Self-Retracting drive PIG through shore discharge hose. Seawater Valve SW30* Workshop   port   bulkhead.      Used   with   seawater   seachest   blowdown   valve   to blowdown   seachest   in   void   2   port.      When   opened,   this   valve   vents   forward seachest  to  atmosphere  through  venting  pipe  to  deckhouse  top.    When  closed, valve forces air from air station into seachest for blowdown. Seawater Valve SW44* ROWPU space rear bulkhead.  Similar function as SW30. *Serves as integral part of both compressed air system and seawater system. 1-11  Equipment specifications a.
