The Immersible Breather Desiccators are designed to protect equipment subjected to immersion in water, preventing overpressure or build-up of a vacuum by allowing a high flow rate of air in and out of the equipment. To further ensure that the equipment/container is free from moisture and only dry air enters, the Immersible Breather Desiccators are equipped with an additional desiccant cartridge to absorb leftover moisture effectively.
