The VV-RV Series.​​​

Rechargeable breather dryers with valves, developed to protect hydraulics, gears, storage tanks and mobile machinery under dusty environments or when minimal pressure build-up is required even with high air flows in indoor, outdoor and offshore use against moisture damage.

Inside the plastic housing, a bed of GIEBEL Xdry® and a 3μm filter ensure effective drying and cleaning of the supply air. A layer of activated carbon adsorbs oil mist when the air is pressed out of the system to protect desiccant and environment from contamination. Once the adsorber is saturated, all components of of the inner workings can be replaced at low cost.
