  • Invention relates to pressure balancing components used to balance the pressure in closed system with the external environment and remove humidity in the closed system.
  • the temperature and pressure of the air in close environment increase due to the elements (engine, card, lamp, etc.) in the close environment.
  • the increasing temperature and pressure damage settings of electronics and mechanical members or cause them to become out of order.
  • the increasing pressure and temperature causes condensation of the humidity in the air of close environment.
