X-Series Air Breathers

High Humidity/Dust Applications
X-Series Breathers are the perfect solution for high humidity and high dust environments. To extend the desiccant's life in these environments, the X-Series incorporates 2 check valves.
The Intake check valve allows airflow into the breather only when differential pressure between the atmosphere and reservoir exceeds a 0.3 psi threshold; while the exhaust check valve other permits air to exit the reservoir when the differential pressure between the reservoir and atmosphere exceeds a 2-1 psi threshold, providing a closed system until air flow is required. The check valves extend the life of the desiccant by allowing the air to flow through the breather only when needed to protect the integrity of the tank.
Typical applications include:

- Paper mills
- Wash down areas
- Steam cleaning rooms
- Mine quarries
In addition to having a rugged design, X-Series breathers include a top cap that can be reused when the desiccant is spent. When the color of the silica gel has turned dark green, remove the reusable top cap from the bottom desiccant cartridge, dispose of the spent dark green desiccant cartridge, then use the same top cap with a replacement cartridge.
