Adsorber VV-R

The GIEBEL adsorbers of the VV-R series are cost-effective solutions which are constructed without valves. Due to the low differential pressure, this adsorber can also be used to ventilate plastic tanks without problems. The adsorbers of this series are filled with 0.1 to 4.6 kg of the desiccant silica gel and therefore have a water absorption capacity of up to 1.84 l. A 3μm filter is used to additionally purify the sucked in air. An activated carbon layer adsorbs oil mist and protects the desiccant and the environment from contamination.

The Adsorbers VV-R are refillable and can be filled with fresh desiccant within a few minutes. The possibility of exchanging the desiccant and wear parts leads to very low operating costs. The use of a refillable version is particularly useful for systems with a permanent air exchange and a shorter service life.

Technical Data

The sucked-in air flows into the adsorber almost without pressure. After flowing into the adsorber, the air is distributed evenly over the cross-section. The pre-filter disc removes coarse dirt particles from the air already at this stage.
When the desiccant silica gel flows through, the water molecules are reliably removed from the air. The gap volume of the granulate is optimally selected with 2 to 5mm grains. This guarantees a minimum pressure build-up and at the same time very good drying efficiency. Thus, at the beginning of the drying process a residual air humidity of max. 2 % rH and a dew point of -40 °C is achieved. Due to the water absorption, the silica gel in the standard version turns from orange to green, indicating the end of the product life cycle. At the end a 3 µm filter ensures that all dirt particles are separated from the ambient air and the silica gel and that the connected system is not contaminated.

With the outflowing air the GIEBEL specific two-stage spill protection prevents larger oil droplets from penetrating into the desiccant. This is supplemented by the activated carbon, which adsorbs the finest oil particles and thus enables the adsorber to regenerate itself.

These adsorbers consist of polycarbonate, polyamide, aluminium, silica gel orange, FKM and can be used for the aeration of all common hydraulic and gear oils and lubricants, fuels, isocyanates. The GIEBEL team is at your disposal for the clarification of resistances.
