Trico Watchdog Desiccant Breathers

desiccant breathers watchdog trico photo

Use the Watchdog Breather to keep machinery free from moisture and contaminants, which cause abrasive wear, shortened lifespan as well as expensive repairs.

The breather contains silica beads that retain moisture from the air as it flows through the unit. For easy determination of time of replacement, the silica changes colour from orange to dark green.

The housing containing the silica granules is constructed in resilient ABS plastic that is transparent for easy inspection of the state of the silica.

Adsorbs Moisture The silica is able to adsorb up to 40% of its own weight
Durable The housing containing the silica granules is constructed in resilient ABS plastic
Visual Indication At reaching maximum adsorption, the silica beads turn dark green, indicating time for replacement
Environmentally Safe The silica is chemically inert, non-corrosive and does not contain heavy metals
Dual Filters The filter at the top clears external particulate from the air, whereas the bottom one reatains dust from the granules
Bi-directional Airflow As air flows in, particulates are retains. When air flows out, it "backflushes" the filter, prolonging its lifespan
