X-Series Breathers are the perfect solution for high humidity and high dust environments. To extend the desiccant’s life, the X-Series incorporates two check valves and a reusable top cap. The check valves provide a closed system until airflow is required, extending the service life of the desiccant. Specifically, the intake check valve allows airflow into the breather only when differential pressure between the atmosphere and fluid reservoir exceeds a 0.1-psi threshold, while the exhaust check valve permits air to exit the reservoir when the differential pressure exceeds a 2.0-psi threshold. A 0.1-psi check valve is also available for exhaust. When the gold silica gel cartridge turns dark green, simply install a new replacement cartridge to keep things moving.

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