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.
Women: Put on a skirt, khakis, or dress pants paired with long sleeve or three-quarter sleeve tops. A casual dress and flats are options as well. Men: Wear a button-down or a polo shirt, paired with khakis, or dress pants. If you so desire, layer with a v-neck sweater, a blazer, or a sport coat. A tie is optional. When to wear it: company party, daily work attire, business lunch meetings.
