Breathing desiccators were developed to provide AGM’s customers with a simple compact solution to two common packaging requirements, minimizing moisture content and protecting from pressure differentials. This is accomplished by mating a desiccant cartridge with a two-way breather valve or combination breather valve/humidity indicator. By specifying a breathing desiccator in their design, customers can pair a custom desiccant cartridge with any one of the following AGM breather valves: TA330
, and TA240
. Similarly styled cartridges are also available for the TA340/TA341 Humi-valve
series. The two styles of cartridge are NOT
These replaceable desiccant cartridges are available in lengths of up to six inches (and longer if approved by AGM’s Engineering Department) and hold approximately 6 grams (0.21 ounces) of Type 4A, 8X12 mesh molecular sieve per inch of cartridge. Constructed with a porous plastic tube, the large surface area provides increased moisture adsorption rates and helps keep the pressure drop through the cartridge to a minimum (typical flow rates are 1/4-1/3 the valve flow rate without the cartridge in place).
