Frequently Asked Questions
What is the primary function of a waterproof breathing valve?
The primary function is to equalize pressure and reduce condensation inside sealed electronic enclosures by allowing air to flow freely. At the same time, it acts as a durable barrier that prevents water, dust, salts, and other contaminants from damaging sensitive internal electronics.
In what applications are these snap-in vent valves commonly used?
They are widely applied in automotive new energy battery packs, automotive ECUs, automotive motors, outdoor communication cabinets, outdoor fans, LED outdoor lamps, combiner boxes, ODF boxes, and electrical control cabinets.
What IP ratings do these breathable membranes achieve?
Depending on the specific configuration and design requirements, the ingress protection (IP) ratings for these breathable membranes range from IP44 up to IP67, IP68, and IP69K.
What is the operating temperature range for the vent valve?
The product is designed to withstand extreme environments, offering a continuous operating temperature service range from -40°C up to 150°C, with raw membrane materials capable of handling temperatures up to 260°C.
How should the product be stored to ensure its 5-year shelf life?
To achieve the maximum 5-year shelf life, the product must be stored in its original, unopened packaging in a controlled environment where the temperature remains below 27°C (80°F) and the relative humidity (RH) is kept under 60%.
