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.

Prevents the ingress of water, dust, and other contaminants into the battery.

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.Suitable for high-pressure cleaning and frequent washdowns.

Maintains reliable protection even under vibration.

All versions (ARVSD, VSD-AR, and ARSD) feature an emergency relief lid, which provides a burst function, opening automatically when internal pressure increase and closes 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.
