Pressure Compensation Device
DA 284 | IP66 / IP68

  • High degree of protection
  • Waterproof membrane
  • Easy to install

In enclosures and housings with a high protection class, differential pressure happens due to internal and external temperature changes. In the event of negative pressure, dust and humidity can be drawn into the enclosure through the seals on the doors. This can cause condensation when the air in the enclosure cools down. The easy-to-fit DA 284 pressure compensation device enables pressure compensation with protection class IP66 (M12: IP67). Additionally, the watertight membrane inside the pressure compensation device allows humidity to escape from the cabinet at overpressure, while preventing water, humidity or dirt intrusion at under pressure.
