Membrane keyboards and similar pressure sensitive equipment are often required to operate under adverse environmental conditions, one of which might be immersion under water. This has resulted in a need for a breathing device that permits air pressure equalization, but protects the equipment from liquid water intrusion.
AGM offers a wide range of Immersion Proof Breathers designed to meet these requirements.
Immersion protection can be provided for liquid water depths of up to 1 meter for as long as 24 hours. Over shorter periods, some Immersion Proof Breathers can withstand water pressure differentials up to 15 psig. Typical operating temperatures are -40°F to 257°F.
Breather flow rates vary from 150 cc per minute to 5000 cc per minute at 1 psig differential.
Solvent and oil resistant breathers are available.
Typical applications include:
- Computer keyboards
- Meteorological instruments
- IP enclosures
- Gearboxes and transmissions
- Hand held terminals
- Battery housings
- Azimuth sealed devices
- Equipment needing protection from hose down requirements.
