The vShield® Protection Door provides a critical defensive barrier and protects bus operators from physical assaults and unwanted passenger interactions. A large, laminated safety glass functions as a sneeze guard, and an electric window allows operator/passenger interaction and can be closed quickly and easily. Two, high-velocity, selectable-speed fans provide optimal air circulation in the cockpit area. An optional MERV 15-rated filter removes airborne bacteria, attached viruses and irritants, including dust, mold and pollen. A heavy-duty, door lock mechanism maintains secured, positive contact and eliminates rattle. The door is manufactured by Vapor Bus International - A Wabtec Company, and is custom designed for each vehicle for exact fit.
