[i]Positive pressure means air is forced in by fans so that it finds its own[/i] [i]way out of vents provided.  The fans need to force it in, not suck it out.[/i][i][/i] [i]And get y'alls minds out of the gutter![/i][i][/i]

Positive pressure working spaces/instrument spaces are use much in industries to keep bad environment out and good environment in.  As engine rooms on offshore drilling rigs, instrument panels in rig floors.  With a + air pressure present, gas cannot invade the area and create an explosive possibility.  Once saw a rig in which gas invade the living quarters and ignited.  Wasn't cute none. -- Best Regards & Happy Trails Andy Chesley @ 57 and ticking Y2KLR650 @ 4K sMiles 97 R11RA (Amiga) @ 14K Miles So Many Roads, So Little Time http://members.deltech.net/aches/
