Temperature fluctuations in a housing in relation to the environment – caused by installed heat generating components and fluctuations in the ambient temperature – result in changing pressure conditions. These pressure changes can lead to the penetration of dust and humidity into the enclosure. In order to compensate for these pressure fluctuations, it is recommended to install a pressure-balancing element whilst retaining the highest protection types (up to IP 69K, high pressure/steam jet cleaning) |
