(18) This type incorporates a combined tubular body and indicator humidity plug. It is screwed into the equipment container from the outside. Air enters the desiccator through an annular inlet channel, which is covered by a strip of Polytetrafluorethylene (PTFE) coated wire mesh to prevent the ingress of rain, dust, insects, etc.
A tube is connected at one end to the annular channel, and the other end is covered by metal gauze to prevent particles of desiccant blocking it. The direction of airflow depends on the relative pressure differentials between the inside of the equipment and the surrounding atmosphere. If the external pressure is greater than the internal pressure, moist airflows from outside, through the annular channel and ...
(18) This range of breather desiccator is designed to be remotely mounted to the exterior of an equipment, allowing the equipment to breathe but provide desiccation at the same time. These units are ideal for providing protection to equipment that does not have adequate internal space to accommodate the required volume of desiccant media to protect the subject item. Special ultra high filtration units are also available and are tailored to specific optical applications.
Note: Add prefix R if RF screening is required. Example: (RXDB6MS 100 Gram Molecular sieve breather desiccator) (RN1BT7 200 Gram Beaded silica gel remote breather) Remote breather are provided with 1/8" or 1/4" compression tube fittings. ...
