Trico Watchdog Desiccant Mini Breather Z-131 2 inch x 2 inch 5 CFM 39131

Watchdog Desiccant Breathers ensure optimum protection of industrial equipment by prohibiting the entry of moisture and particulate contamination. Contaminants enter industrial equipment as pressure differentials or fluid level changes occur. The Watchdog Desiccant Breathers are ideal for circulating oil systems, oil sumps, process tanks, storage tanks, vacuum systems, hydraulic systems, transformer cases, or anywhere that equipment needs to be dry and clean.

Watchdog Desiccant Breathers perform two very important functions.

1. They adsorb unwanted moisture inside industrial equipment using silica gel technology. Unwanted moisture can lead to corrosion, shortened fluid life, and additive depletion.
2. They collect airborne solid particles by means of a dual, anti-static filter system. This reduces the amount of abrasive and damaging contaminants that create sludge build-up inside the fluid reservoir.

Watchdog Desiccant Breathers are a unique particle filtration and water removal system. 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.

Options

Watchdog Desiccant Breathers

• Water Vapor Adsorbent. The silica gel used adsorbs up to 40% of its own weight.
• Color Indicator. When maximum adsorption is reached the silica gel turns from orange to dark green, indicating replacement is needed. The silica gel used is chemically inert, non-corrosive, and does not contain cobalt chloride, a heavy metal. The color changing dye used is environmentally safe and meets all health and safety requirements.
• Dual Filtration System. A two micron filter (99% efficiency) is located at the top and bottom of the silica gel bed. The top filter removes particle contamination from atmospheric air and the bottom helps with dust created by the silica gel beads contacting each other.
• Activated Carbon. As air is expelled, it passes through activated carbon which removes oil vapors, fumes, and odors (except for part numbers 39131, 39132, 39133, and 39134).
• Bi-directional Air Flow. A 360º air flow allows air to be breathed in and out as fluid level changes or differential pressures occur. Expelled air “backflushes” the particulate filter to prolong the life of the breather.
• Durable construction – Watchdog Desiccant Breathers are manufactured from rugged ABS plastic and impact modified acrylic.
• To install Watchdog Desiccant Breathers use one of several Watchdog Breather Adapters

Water Capacity

Listed below is the maximum water capacity for the Watchdog Desiccant Breathers by part number.

Note: Water capacity is a function of relative humidity. At higher humidity levels, the silica gel adsorbs (holds) a larger amount of water. The maximum is approximately 40% of the weight of the silica gel at about 90% humidity.
