Venting and auto burst plugs

Battery ventilation components made with Glass Fiber reinforced Nylon (PA66) and a stainless steel inner. Designed to prevent a dangerous build up of gasses within the battery reducing the risk of explosion, fire and damage. Offering continuous ventilation and a burst safety function, the vents perform excellently under vibration and are able to resist the ingress of water, dust and other contaminants. They are suitable for high pressure cleaning and applications where frequent washing is necessary.

These products meet protection classes IP66, IP67, IP68 and IP69K, while optimising the lifetime of Li-ion batteries and providing safety in case of an explosion, suitable for use in applications such as electric vehicles, electric trains and stationary batteries for energy storage.

Use the Bimed VentCalculator to work out your required pressure compensation.
  • IP66, IP67, IP68, IP69K prevents the ingress of water, dust, and other contaminants into the battery
  • Balances internal pressure in batteries, reducing the risk of damage and explosion
  • Balanced pressure prevents excessive stress on battery gaskets, extending their service life
  • Includes a safety burst system that activates in cases of overpressure or thermal events
  • Ingress protection from dust, water, and other contaminants
  • Provides reliable sealing performance even under vibration
  • Suitable for high-pressure cleaning and frequent washing applications
  • While the ARVSD and VSD-AR models offer both continuous ventilation and a burst safety function, the ARSD model provides only the burst function
  • All versions (ARVSD, VSD-AR, and ARSD) feature an emergency burst function, opening automatically when internal pressure increases and closing when pressure drops, ensuring safe and controlled operation
  • ARVSD and VSD-AR provide a burst function along with ventilation, while ARSD provides only a burst function
