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 water intrusion.
AGM offers a wide range of Immersion Proof Breather Desiccators and Breather
Desiccators designed to meet these requirements. These breathers,
due to the nature of their construction, only permit a low air
flow rate, approximately 150 cc per minute at 1 psig differential.
Immersion protection can be provided for liquid water depths of
up to 1 meter for as long as 24 hours. Immersion Proof Breathers can withstand
water pressure differentials up to 15 psig and will limit water
vapor transmission to 0.05 grams in 24 hours. They can operate
at temperatures from -40°F to 257°F.
These Immersion Proof Breathers are solvent and oil resistant, have high filtration
efficiency (nominal filtration is 1 micron), are easily installed
and are available in a variety of housing materials in thread sizes
from M3 to M16.
Typical applications include: computer keyboards, meteorological
instruments, IP enclosures, gearboxes and transmissions, hand held
terminals, battery housings, azimuth sealed devices and equipment
needing protection from hose down requirements.
