Waterproof Breathers prevent water damage to enclosures and instruments

Waterproof Breathers prevent water damage to enclosures and instruments

Lightweight materials used in the manufacture of electronic products often give designers a dilemma. They either have to restrict the applications or to increase the strength of the enclosure walls. Heat can cause a pressure build-up within an enclosure and without adequate venting the lightweight material could fracture.

These devices allow an enclosure to "breathe" (transfer air in and out) but will withstand driving rain or even total immersion in water up to two metres. They are made from robust and hard wearing materials. The breathers can pass high flow rates of air which can result from rapid variations in pressure, caused by temperature or altitude changes.

The breathers can be screwed into a threaded boss or mounted through a hole, using a lock nut that is available.

If a controlled environment within equipment is required, then a humidity adsorber can be fitted in the rear of most immersion breathers. These adsorbers are filled with desiccants to prevent humidity damage and condensation.
