5) Filler Breather (FSB)
Description
Filler Breathers serve a dual role in hydraulic systems, functioning as both a reservoir filling point and a breathing element that works alongside the hydraulic filter in India to prevent airborne contaminants from entering. They ensure continuous clean air exchange, maintaining overall system integrity and effectively protecting hydraulic fluid from dust, moisture, and debris.
Filler Breathers can be mounted on the top or side of the reservoir and come in various configurations, with or without strainers. Designed for easy filling, inspection, and maintenance, they work with the hydraulic filter to ensure effective system protection in both stationary and mobile hydraulic applications.
