Dryers, Medical-Air, Membrane
Definition : Medical-air dryers designed to remove moisture from the air using membrane-filtration techniques. Typically, the compressed air to be dried passes through a set of hollow-fiber membranes, in which the water vapor permeates the membranes, drying the compressed air. Simultaneously a small portion of the dry air is redirected along the length of the fibers to sweep out the water vapor that has permeated the membrane; then the moisture-laden sweep gas is vented to the atmosphere while dry air is supplied to the distribution system. Membrane medical-air dryers may be equipped with filters for removing liquid oil aerosols and mists, and purifiers for removing solid and liquid particles and gaseous impurities such as carbon monoxide; these devices are frequently included as an integral part of medical-air supply systems.
