Guardian Desiccant Breather - 5" tall, Silica - 1" NPT
The Guardian with Isolation Check Valve provides maximum protection for the silica gel. Exhausting air flowing from a fluid reservoir may carry oil mist, heavy vapors or bring moisture from contaminated oil. The Isolation Check Valve acts as a barrier to splashing fluids.
Guardian Desiccant Breather - 5" tall, Silica - 1" NPT
Ideal for most Applications
GUARDIAN is Air Sentry's industry leading breather series. Some models feature an isolation check valve that keeps exhaust air from depleting the desiccant and protects from volatile fumes and splashing fluids. The GUARDIAN's casing is constructed from Tritan®, a patented material highly resistant to impact and chemicals with a broad range of operating temperatures. These unique features equate to a longer life for your breather and your equipment.
GUARDIAN's modular construction and optional add-on features allow you to customize each Guardian model to your specific application requirements. From the isolation check valve, to its stackable design, from its wash-down cap, or its compound indicating gauge, to the high-capacity HEPA filter, the GUARDIAN will last longer and reduce downtime giving you the flexibility you need to protect your industrial assets.
Summary
- Ideal for Most Applications The only desiccant breather series that Air Sentry recommends for diesel fuel applications (not recommended for other fuel applications).

Note: Guardian™ Cartridges should only be used with Guardian™ top and bottom caps. When using cartridges with the Isolation Check Valve, always ensure the valve is at the bottom of the cartridge. When using the Modular Stack Ring™, do not stack multiple cartridges with Isolation Check Valves. Use the Isolation Check Valve on the bottom cartridge only.
