Hospital special

On our way further in, we pass the climbingshaft and we enter the ventilationroom.

The yellow boxes are the primary filters for the outside air. These boxes had a flexible hose-connection at the front (gone), which led to the inlets of 3 airpumps. The pumps were once placed on the mountings.

The outlets of the airpumps were connected to this complex system. The left handed pipes were attached to two big replaceble airfilters. The ones at the right transport the filtered air into the entire bunker.
