If anybody is looking at the auto dry settings and wondering why Delicate is between Regular and Bulky instead of right near the end of the automatic cycle like in a GE dryer, it is because of the 125F temperature setting for delicates. The dryer heats to 125F faster so not only does that make the timer motor start running sooner than it does at the higher temperature settings but, as John said, at the lower temperature the drying is slower. That is because there is less temperature differential between the room temperature and the temperature inside the dryer so condensing the moisture is harder. Filtrator dryers evaporate moisture far faster than they can condense it. I remember how each time I would clean all of the lint out of the outer tub, the first load would dry really fast and water would condense so fast that the Filtrator apparatus could not quite handle it so it would leak onto the floor, like a puppy. While it would defeat the purpose of the machine, I have often wondered how fast one would dry outside in the winter. There is all of that empty space on the right side of the Filtrator cartridge where a refrigeration coil could go to chill the air passing over the Filtrator. You would still have the waste heat, but maybe faster drying.
In case you are wondering about drying wash'n wear, you have to pull the Filtrator cartridge out a couple of inches to the wash'n wear mark on it. This does not make a linty mess because those fabrics are not linty like cottons, although you have to clean any lint off that is on the cartridge before starting the w'n w load. Having the cartridge pulled out allows for more air flow through the drying chamber which means a better cool down at the end of the cycle and the last 10 minutes are a cooldown on the timed cycle.
