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 TA340 Humi-valve
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).
