Air Sentry G12S1NGC Desiccant Breather

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.

All Guardian-Series models feature two 2 micron filters, one on the inlet and a second on the outlet.

Operating Temperature: -20°F (-29°C) to +200F (+93°C)
