COMMERCIAL FACILITIES Overview There are many areas and facilities that fall into the generalized category of "COMMERCIAL APPLICATIONS". Bowling Centers, Fraternal Organizations, Restaurants, Bars and Night Clubs, Hair and Nail Salons, Lobbies, and Waiting Areas can all be considered a commercial application. All of these areas generally have lesser requirements than health care and clean room facilities. Smoke and odors, mold and mildew, and dust are primary considerations in this category and the size of the particulates is generally larger. Because of the different characteristics of the undesireable contaminates, different systems are necessary.
