Prevent damage to enclosures and instruments Immersion Proof Breathers allow an enclosure to “breathe” (transfer air in and out) but will withstand driving rain, sand, pollen, total immersion, dust and airborne contaminants. The breathers can pass high flow rates of air which result from rapid variations in pressure, caused by temperature or altitude changes. If a controlled environment within an equipment is required, A humidity adsorber can be fitted in most immersion breathers. These adsorbers are filled with desiccants to prevent humidity damage and condensation. Computer Keyboards Pressure Vs.
