DC-HG-1 Desiccant Breather
Des-Case HydroGuard® breathers uniquely feature an expansion chamber and internal check valves that create a nearly-sealed system. Designed specifically for steady-state operations with minimal temperature fluctuations, these breathers provide excellent protection in continuous duty applications.

1–Domed Cap
A domed cap allows for better washdown runoff.
2–Expansion Chamber
The diaphragm allows for expansion/contraction of the air within the casing as a result of temperature variations during steady-state operations.
3–External Ribs
External ribs on shell to create greater durability and grip when installing or replacing breather.
4–Integrated Nylon Standpipe
The integrated standpipe provides excellent vibration resistance and dissipates impact throughout the unit, eliminating weak points. It also allows even airflow distribution throughout the unit, eliminating inaccurate readings of desiccant saturation.
5–Integrated Drip Ring
An integrated drip ring keeps shedding water from entering the vent holes.
6–Threaded Mounting
Easily replaces standard filler/breather cap with multi-fit connection or one of several adapters.
7–Larger, High-Capacity Check Valves
High-capacity check valves allow for increased airflow at low cracking pressure.
8-Filter Element
Polyester filter element removes airborne contamination to 3-micron absolute. Unique loops allow particles to release during system exhalation, helping to increase breather life.
9–Enhanced Seal
An enhanced seal eliminates potential for airflow bypass.
