Immersion Proof Breathers are designed for pressure-sensitive equipment that operates under harsh environmental conditions, such as altitude changes, temperature cycling, sandy/dusty places and even water immersion. Made of robust and durable material, Immersion Proof Breathers can prevent distortion or damages caused by the conditions mentioned above. Immersion Proof Breathers are also made for easy installation in which they can be mounted through a hole using the supplied lock nut or screwed into a threaded boss. Incorporating a desiccant humidity adsorber into the rear to the Immersion Breathers is also possible to protect the equipment from humidity damage and condensation. The Immersion Proof Breathers are not only able to prevent intrusion of liquid water, but they can also equalise pressure in the equipment simultaneously.
