Effect of PMF protective vent on WP series box WP series enclosure comes with a silicone gasket, which allows the enclosure to be airtight when assembled. When used in environments where there are large temperature fluctuations or differences, the internal and external pressure will become uneven. If this pressure within is unable to be properly vented, it may cause the enclosure to deform and warp. By installing the PMF series protective vent, it will assist in equalizing the air pressure, and prevent potential deformation. Test Conditions Device : Constant temperature/humidity test chamber...
