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. Able to be easily installed – screw in the threaded boss or mount using the locknut provided.
