摘要

The apparatus has a pressure equalization unit, where the apparatus is connected with an device by a hose for an air exchange. The pressure equalization unit exhibits a pressure-dependent volume, an air-permeable housing and a desiccant. A humidity display is integrally designed together with the pressure equalization unit for displaying the air humidity. A humidity sensor is connectable with a bus system for data exchange. An independent claim is also included for a system with an pressure equalizing apparatus.
