Designed to extend the lifetime of Li-Ion batteries by providing ventilation and pressure relief.

Includes a built-in burst system to ensure safety in case of overpressure or thermal events.

Prevents damage to battery housings by relieving internal pressure and reducing the risk of rupture.

Provides ventilation while continuously balancing internal pressure within the battery housing, preventing stress on gaskets

Provides reliable protection against water, dust, and contaminants while allowing safe airflow.

Manufactured from high-quality, durable, corrosion-resistant materials for long service life.

Easy to install and maintain, ensuring safe operation of battery systems in indoor and outdoor environments.

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.
