Presair’s pneumatic-electric converter box (PBA-01) combined with a bellow (F800BA) can be used in virtually endless ways. In this example, it is being used to control attic lighting. Attics are often very dark and cramped, definitely not an ideal setting for installing lighting. However, Presair’s air-switching solution can make it much easier to quickly make a functional lighting setup. It can also be customized and scaled to fit the space perfectly.
