The Series MA-RV Desiccant Breather Dryer is a refillable, low-maintenance solution designed for use in ATEX Zone II 2 G / D IIC T4 environments, providing reliable moisture protection for hydraulic power packs, gearboxes, storage tanks, and mobile machinery. With a robust aluminum housing and check valves, this dryer is suitable for harsh environments and aggressive operating fluids, both indoors and outdoors. Inside, the GIEBEL Xdry® desiccant bed and a 3μm filter ensure effective air drying and cleaning. An activated carbon layer adsorbs oil mist to protect both the desiccant and the surrounding environment from contamination. The adsorber components are easily replaceable at a low cost, and the units are available with either FKM or EPDM seals, making them ideal for use with aggressive substances. Certified under the ATEX product directive 2014/34/EU, the MA-RV breather dryer offers a durable, cost-effective solution for moisture control in challenging environments.
