Pentair
Stealth Active Breather System Research has shown that over half of all lubricant contamination comes from outside the system. Most machines that depend on lubrication or hydraulics are designed to 'breathe ', making them vulnerable to moisture and particulate contamination. The conventional desiccant breathers use filter media to remove the particles, and silica gel beads to remove moisture from the air. In many environments, it can become very costly to keep replacing these breathers. Stealth ABS controls the moisture... (read more)Browse Filtration Equipment Datasheets for Pentair -
