3.2.9 Vent port
A gas permeable vent has been installed on the iRM4451nn00-2 iRRH to help
equalize air pressure inside the enclosure and prevent contaminants such as
water, salt and dust from getting inside (see
Figure 3-12). The vent fitting has a
gas-permeable membrane integrated into a screw-in fitting. It meets the IEC
60529 standard for enclosure ingress protection against particulates and liquids.
The vent should function maintenance-free over the lifetime of the
iRM4451nn00-2.
