An air dryer might cause about 0.3 bar pressure drop in your compressed air system. Basically this means that you have to run your compressor at a higher pressure. This of course will result in more energy consumption by your compressor.
Dressing for a gala event is rather simple. It is typically a formal wear occasion. For men, that equates to a tuxedo or at the very least a suit and tie. For women, formal wear is typically a long gown with high heels, matching accessories and jewelry.
The nice part is that both men and women can carry the tie off with panache. Adding the tie to an outfit makes it more elegant and makes the person wearing it look more dignified. A tie when worn to a formal event adds so much class to the whole outfit. It is best when paired with a suit or tuxedo.
