486-3542 Hydraulic Breather
Cat® hydraulic breathers regulate air pressure within the hydraulic system, keeping contaminants out and maintaining optimal system performance.
Description
The hydraulic breather maintains proper pressure and keeps contaminants such as dust, moisture and particles out of the hydraulic oil. It consists of a housing containing a filter element, desiccant and relief valve, which helps prevent costly failures, reduce maintenance requirements, and improve the overall reliability and efficiency of heavy machinery with hydraulic systems.
Attributes
- Prevents damage to critical components and ensures smooth operation.
- Helps keep hydraulic oil dry, avoiding water-related problems.
- Prevents cavitation and maintains system efficiency.
Applications
The hydraulic breather filters out contaminants to keep hydraulic oil clean and absorbs moisture to prevent corrosion and fluid degradation.
