Desiccant Breathers are air intake devices that utilize desiccant media to remove moisture from the surrounding air. They protect equipment from corrosion and moisture-related breakdowns by ensuring dry air enters enclosures. This can improve reliability and extend equipment lifespan.

Air Sentry set the industry gold standard with their first line of contamination control breathers in 1997 and today that standard is raised with GUARDIAN.
