Hi Timless Tanning
I too have the T200, only last night I did a party of seven, yes the pipe gets hot and as Jaffacake has already said, just take care of the metal parts when taking apart at the end of the session.
It is a great little machine and I think with care it will last a long time. I can not believe how fine the spray is.
Again as Jaffacake and also Colin has mentioned you can use masks intended for the building industry. Only yesterday I purchased a couple from Homebase, no sorry Colin not B&Q this time, lol!!! They are intended for paint spraying, contain charcoal and have a special breathing piece on the front and will last several spray sessions a time. I have to be particularly careful after having chest surgery and radiotherapy on my chest.
Happy tanning to you X
