Why Desiccant Filters Are Essential
Atmospheric air and moisture are continuous threats to the efficient operation of hydraulic systems and gearboxes. When a reservoir or gearbox breathes, air carrying water vapor and fine particles enters the system. Due to temperature fluctuations, this vapor condenses into water, accelerating fluid oxidation and causing system damage.
Protection Beyond Standard Breathers
A desiccant filter replaces the standard dust or breather cap, providing advanced filtration to block even the smallest particulates and moisture. This ensures better fluid cleanliness, improved system reliability, and longer equipment life.
These filters are crucial in industries where moisture control and contamination prevention directly impact performance and reduce costly downtime.
How Desiccant Filters Work
Desiccant filters combine air filtration and moisture absorption in one lightweight breather unit. As air enters, it passes through a fine 2-micron absolute-rated filter, removing solid particulates. Simultaneously, the drying agent absorbs moisture to protect the hydraulic fluid. The drying agent changes color (orange to dark green, or blue to pink) as it becomes saturated, making it easy to identify when replacement is needed—ensuring reservoir cleanliness at all times.
Advanced Protection for Your Hydraulic Systems
Built with a durable polycarbonate casing, impact-resistant standpipe, and advanced check-valve technology, our inline desiccant filters offer long-lasting protection against both moisture and particulate contamination. These filters are ideal for industrial and mobile applications, helping equipment run smoothly and reducing costly downtime.
