HBBVP-03 is a ventilation plug by Bimed which prevents water vapor congestion inside enclosure. Made from stainless steel with a hydrophobic and oleophobic membrane. Thread: M20x1,5, 6 mm in length. Water intrusion pressure: 0,2 bar, average air flow: 120. Protection degree: IP67/IP68. Operating temperatures from -20 to +100 degrees Celsius.
Pressure balance elements are an essential part of the housings. They have a ventilation function, ensuring air exchange, but more importantly they equalize the pressure, thus preventing the condensation of water vapor. Due to this, the components located inside the enclosure gain additional protection against moisture.
