They prevent destructive contaminants from entering industrial equipment as air is breathed in and out due to thermal expansion or fluid level changes. They feature visual indication of the silica for replacement, which turns from orange to dark green.
By allowing only clean, dry air into industrial equipment, the Watchdog Desiccant Breathers prolong fluid life, reduce abrasive wear, downtime, and repair costs.
