Air Sentry Guardian Series Breather - SILICA - 1 inchNPT - WITH ISOLATION CHECK VALVE

Tough conditions call for even tougher solutions. GUARDIAN™ Breathers from Air Sentry® use revolutionary designs and materials to significantly reduce maintenance intervals. This extends lubricant and equipment life and lowers costs.

Guardian's industry first Isolation Check Valve prevents oil mist and fuel vapors from reaching the desiccant media and reducing air flow which could potentially damage equipment. Replaceable cartridge designs reduce cost and waste, and the durable outer casing is made of BPA-free, recyclable Tritan™ material.

Check valves in the reusable top cap extend the life of the breather by only drying the air drawn into the head-space of the gearbox, tank, or reservoir. The reversed check valves in the steel reinforced base means exhaust air does not pass back through the desiccant, which further lengthens the life cycle of the breather.

Particulate contamination, mixed with the system's fluid or lubricant, acts as an abrasive compound that greatly increases fluid component wear resulting in equipment failures and higher maintenance cost.

Moisture in a gearbox can cause it to rust from within. This rust flakes in the lubricant, producing additional abrasive material, premature wear and failures.

Small hydraulic pumps are sensitive to these problems. Hydraulic valves, seals and other components require contamination free fluid to function at peak effectiveness and accuracy. These components are increasingly expensive to rebuild or replace.

Water vapor is removed as the air travels through a bed of silica gel, the highest capacity adsorbent available. After being dried, the air passes through a 2 micron solid particle filter and enters the gearbox or reservoir clean and dry.

Air Sentry is gold when active and dark green when it has to be replaced.

A threaded mounting hole (1/2" NPT) allows easy installation using a wide variety of standard connectors. All models are rated for 10 CFM airflow.

• Height: 9"
• Diameter: 5.125"
• Mounting Connection: Female 1" NPT
• Silica Gel: Yes
• Maximum Adsorption Capacity: 9.2 (ml) capacity in fluid ounces
• Maximum Air Flow: 25 cfm
• Maximum Reservoir Fluid Flow: 187 gpm
• Type of medium: silica gel
• Isolation Check Valve: No

• GUARDIAN Shield Wash Down Cap:
• The cap provides a barrier for environments where equipment wash down happens frequently. This prevents any direct spray from opening check valves in the top cap. It's designed for use in food processing, mining operations, pulp and paper facilities and outdoor applications.
• Guardian High Capacity Air Filter:
• Can be used with a desiccant cartridge or as a stand alone particle filter. Ideal for extremely dirty/dusty environments.
• Tritan™ Construction:
• GUARDIAN is constructed of Tritan™. This patented material is the most chemical-, temperature-, and impact-resistant combination casing on the market.
• Stackable:
• Stack cartridges to extend the life of breathers even further using the Modular Stack Ring. This proprietary feature lengthens the service life, reducing cost and maintenance intervals.
• Isolation Check Valve:
• GUARDIAN features an isolation check valve, which isolates the adsorbent from exhaust air to lengthen the service life of the desiccant while also protecting it from volatile and splashing fluids.
• Integrated Compound Vacuum/Pressure Gauge:
• This proprietary feature is a true-life accurate indicator of filter conditions.
