The Mini Immersion Breathers are designed for smaller equipment with a limited amount of space available. This equipment includes membrane keyboards, remote control devices, battery packs, and handheld radios. Incorporated with a hydrophobic membrane, this makes the Mini Immersion Breather impermeable for the transfer of liquid. It also allows air to pass through to prevent pressure build-up. Desiccants can also be filled to the Mini Immersion Breathers to dry the air entering the equipment. They are also able to be easily installed by screwing in the threaded boss or mount using the locknut provided.
