Compressor

The compressor is used to replenish the compressed air supply of the boat while surfaced. The handle to turn the compressor on or off is located at the rear port side of the control room and takes the form of a fist sized red lever. There are two compressed air gauges in the control room. One next to the bilge level gauge on the starboard rear side of the control room as well as one on the main ballast tank station in the middle starboard side. The compressor will automatically turn it self off when the compressed air is filled to the top of the green line, which is the max safe pressure. It is not possible to over pressurize the tanks.

Although it is good practice to top off the compressed air supply while not engaged in combat, it is often not necessary to refill the tanks, as the boat is able to operate with compressed air levels almost completely depleted. The downside of low compressed air reserves is that blowing the ballast tanks takes longer than necessary.
