What About Our Many Fans?
Sven July 8th, 2010
Presumably, this shaft once vented into open air, but its operational days are long past. The big extractor fans remain, however.

The rumble of commercial exhaust fans came and went, but it was clear this section was no longer at all active. No air movement in the shaft room, nor through the labyrinthine concrete corridors that lead to it. Occasional filter bays along the way were long neglected. It seems this system is no longer connected in any sensible way to anything much at all. Of course, there is still a way in, though it’s incidental, and fairly obviously not built for human traversal. Whatever works, though!
Unfortunately, the shaft itself currently boasts a floor of stagnant water – maybe the upper section breaches the real world after all, and lets rain in? I’m curious, after thinking about this, and will have to see if I can find any remnant of it aboveground.

On a chillly night aboveground, it was quite pleasant in the warm, enclosed environment. Anything not wet is covered in dust, however – there are probably better places to hang out with friends. :)

Quite tasteful use of colours there :)
A clown threw up on my camera :P
It’s always looked really crap in there and on our first visit it was mid-shin deep in water inside the fan chamber. We constructed a make-shift bridge using planks of wood and milk crates we found in there. I may well have some p&s shots of it in that state, I’ll have a dig. Also back then the filters were still attached top and bottom, so getting right into the fan chamber required one to lie sideways and squeeze through, getting covered top to bottom in black nastiness.
Late at night the fans were often turned off, perhaps you should return at an earlier time? Being inside the chamber while the fans are running is truly something.
Well, it’s interesting to know that the milk crates and planks have been there that long. I had no idea the thing was active, though! Other fans switched on and off during the evening (I was there around… 8pm?), but I assumed those were adjcadent, but unconnected, systems. I wonder what this ventilates, then, that needs filtration?
I talked to a couple of people and the unanimous opinion is that the fans are off, for good; which is a real shame because watching small pieces of polystyrene hover up into them running was fun.
Alas :( No Priscilla-style mylar train shots for me, then.
