The VV-DV Series.
Disposable breather dryers, 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.
The plastic housing is filled with GIEBEL Xdry® and also has a 3μm filter to ensure effective drying and cleaning of the supply air. A layer of activated carbon adsorbs escaping oil mist when the air is pressed out of the system to protect desiccant and environment from contamination. Once the adsorber is saturated, the cartridge is replaced. The stable and frost-proof valve part remains on the system. It protects the adsorber from unnecessary loading thus enables longer maintenance intervals.

Flowchart
The sucked-in air opens the valves in the lower part of the adsorber already at approx. 6mbar. After flowing into the adsorber, the air is evenly distributed over the cross-section. The pre-filter disc frees the air from coarse dirt particles.
When flowing through the desiccant, the water molecules are reliably removed from the air. The gap volume of the granulate is optimally selected with 2 to 5 mm grain size and guarantees a minimum pressure build-up with very good drying efficiency at the same time. Thus, a residual air humidity of max. 2% rH and a dew point of -40°C are achieved at the beginning of the drying process. A 3µm filter ensures that all dirt particles are separated from the ambient air and the GIEBEL Xdry® fill and that the connected plant is not contaminated.
When air is discharged, a two-stage slosh protection and a layer of activated carbon prevent oil droplets, oil particles and oil mist from entering the desiccant, thus enabling the adsorber to self-regenerate.
As saturation increases, the orange silica gel grains of the GIEBEL Xdry® fill turn green. If the silica gel grains have turned completely green, the adsorber must be replaced.

Replacement cartridges.
We have developed replacement cartridges for the VV-DV series. Unscrew the loaded cartridge from the valve section and screw on a new cartridge.
