VV-D

GIEBEL adsorbers of VV-D series are cost-effective solutions without valves. The adsorbers are filled with 0.1 to 4.6 kg of silica gel and have a water absorption capacity of up to 1.84 l. Thanks to a 3μm filter, the aspirated air is additionally purified. An activated carbon layer adsorbs oil mist and protects the desiccant and the environment from contamination.

After saturation, the adsorber is replaced. Especially for plants with a permanent air exchange and only short maintenance periods, the use of the disposable version makes sense.

VV-DV

Adsorbers of the VV-DV series have a stable valve part and are designed with a disposable replacement cartridge – this ensures effective protection of the system to be aerated as well as simple and quick maintenance.
With the stable and frost-proof valve part, the adsorbers are optimally suited for extreme, dusty ambient conditions. Due to the large valve cross-sections, pressure build-up is minimal even at high air flows. In addition, this series contains a bed of activated carbon granules and slosh protection to separate escaping oil mist.

VV-R

Adsorbers of the VV-R series are cost-effective solutions without valves. Due to the low differential pressure, they can also be used for the aeration of plastic containers. The adsorbers are filled with 0.1 to 4.6 kg of the desiccant silica gel and thus have a water absorption capacity of up to 1.84 l. A 3μm filter cleans the sucked in air and an activated carbon layer adsorbs oil mist and protects the desiccant as well as the environment from contamination.
VV-R adsorbers are refillable. The ability to replace desiccant and wear parts leads to very low operating costs. We recommend their use especially on plants with permanent air exchange and short downtimes.

VV-RV

Adsorbers of the VV-RV series have a stable valve part made of glass fiber reinforced
polyamide and are equipped with a refillable adsorber cartridge.
Thanks to the valve part, these adsorbers are optimally suited for extreme, dusty ambient conditions. They are used, for example, on hydraulic power units, gearboxes and storage tanks. Due to the large valve cross-sections, the pressure build-up is minimal even at high air flows. In addition, this series contains an activated carbon layer as well as an overflow protection to separate escaping oil mist. This ensures cyclic self-regeneration and thus very long maintenance intervals.

MA-R

Adsorbers of the all-aluminum MA-R series are particularly robust aeration dryers which, due to their high resistances, are also used when isocyanates, polyols, DOT4, SKYDROL, solvents or oils are to be protected against the entry of moisture. They are often used on 200l barrels and 1000l IBCs and are available with FKM or EPDM seals. They can also be used in accordance to ATEX product directive 2014/34/EU in zone II 2 G / D IIC T4.
Since the MA-R series are refillable adsorbers, the investment pays off after a short time. Desiccant and wear parts can be replaced at low cost. The increasing saturation of the desiccant can be observed through the viewing window by means of a color change from orange to green. If the desiccant is completely colored green, the silica gel must be replaced.

MA-RV

MA-RV adsorbers consist of an aluminum housing with valve section and are used for aerating aggressive substances or for use in harsh environments. The very robust housing withstands the most adverse conditions and optimally protects the system to be aerated from water ingress. The adsorbers are filled with up to approx. 10 kg of desiccant and can also be used with FKM or EPDM seals for the aeration of SKYDROL, DOT4 brake fluids and other hydraulic fluids. In addition to effective air drying, particle separation down to 3μm is achieved.
MA-RV adsorbers can be used in zone II 2 G / D IIC T4 according to ATEX product directive 2014/34/EU. The dessicants saturation is controlled via a viewing window.

ME-RV

ME-RV adsorbers have a housing made of A4 stainless steel. With up to 5.2 kg of desiccant, they are also suitable for venting large hydraulic tanks in offshore operations, as well as gearboxes in the chemical industry and storage tanks.
Use in accordance with ATEX product directive 2014/34/EU in zone II 2 G / D IIC T4 is possible, as well as in accordance with corrosivity category C5-M. On gearboxes or hydraulic tanks on ship decks, the separate valve part protects the desiccant as well as oils and lubricants from contamination and damage by water during wave action. The adsorber is refillable, making it quick and inexpensive to maintain. Wear parts and desiccant are quickly replaced and the protection of the system to be ventilated is restored.

MS-R

MS-R adsorbers have a housing made of A4 stainless steel and can – with a filling capacity of 50kg or 150kg of desiccant – absorb up to 20l or 60l of water from the air. Thus they have a long maintenance interval and can efficiently ventilate large storage tanks, even in offshore applications.
Use in accordance with ATEX product directive 2014/34/EU in zone II 2 G / D IIC T4 is also possible, as is use in accordance with corrosivity category C5-M. The loaded silica gel can be quickly removed at two large openings and replaced by fresh gel. In combination with a venting system and a supply air valve, the air flow into and out of a tank can be controlled in a targeted manner. Due to their optimized design, these adsorbers can be maintained very quickly and at low cost. The wearing parts and the desiccant are quickly inserted and the protection of the plant to be ventilated is restored.

VG-D

GIEBEL adsorbers of the VG-D series are used for adsorption of oil mists. Thanks to the combination of sloshing protection, oil demister and a high amount of activated carbon, the air flowing out of hydraulic tanks, gearboxes and drums is cleaned and the environment is protected from contamination with oil.
VG-D adsorbers are used, for example, on turbo gearboxes, test benches and circulating oil lubrication systems. The effective design of the series prevents the escape of larger and smaller oil aerosols. The adsorbers are available in a disposable version and are completely exchanged after saturation (discoloration of the white layer). This means that maintenance can be carried out within a short time. The size is selected on the basis of the plant size and the amount of pollutants escaping, in order to ensure high efficiency and a long service life.

The wearing parts as well as the desiccant are quickly replaced and the protection of the plant to be ventilated is restored.

VL-D

VL-D adsorbers are inline filters with connections on both sides for mounting in a pipe. They are used for drying air streams or separating certain substances in electronic, optical or
other systems. Depending on the application, they are filled with silica gel or molecular sieve and are completely replaced after being loaded. In addition to the desiccant, a filter is integrated to separate abrasion and ambient dirt.

VL-R

VL-R adsorbers are refillable inline adsorbers with threaded connections on both sides. They can be used in small systems, such as laser systems, up to large storage tanks to separate water molecules from the supply air or pollutants from the exhaust air.
Depending on the task, the filling consists of silica gel, molecular sieve or activated carbon.
With a DN50 thread, large volume flows can also be fed through the adsorber. A metal lid with quick-release fasteners facilitates maintenance and reduces operating costs. Stability, UV resistance and a long service life are guaranteed here.

VM-R

VM-R adsorbers are inline filters for use in extremely harsh conditions or in explosion protection zones according to ATEX 2014. Consisting of a metal housing with threaded connections on both sides, these adsorbers can be installed in pipelines and ensure that pollutants or water are separated and the plant to be ventilated is protected.
The filling is selected according to the requirements of the plant. If adsorbents with a color indicator are filled in, their color change can be observed through the viewing window. This makes it easy to determine when the fill is fully loaded and needs to be replaced.

PL-R

PL-R series adsorbers are high pressure inline filters. They are completely made of aluminum and can be loaded up to 8bar, or 116psi. With a filling capacity of 1.9kg or 4.0kg of silica gel, these adsorbers absorb up to 0.8l or 1.6l of water from the air when used in compressed air lines. Their special design allows them to be used in high-pressure applications that require very dry air – for example, in PUR metering systems. The use according to ATEX product directive 2014 in zone II 2 G/D IIC T4 is possible.
PL-R adsorbers can also be filled with other desiccants – including molecular sieve, if other substances are to be adsorbed in addition to moisture separation.

ES-R

Adsorbers of the ES-R series are used in closed rooms and containers to protect the contents from damage caused by humidity (e.g. in switch cabinets, server cabinets, display cases or storage containers for moisture-sensitive goods). The adsorber indicates by a color change when the desiccant is saturated and needs to be regenerated/replaced.

HS-D

HS-D series adsorbers protect gearboxes from water droplet ingress while allowing them to breathe. Using an ePTFE filter in the core of the durable polyamide housing, gear oil is protected from water contamination, even when the gear is used outdoors or cleaned with water.
The 0.3 micrometer pores of the membrane filter retain water or oil, but allow air to flow through. The pressure build-up remains low.
The HS-D membrane filters are an excellent alternative to adsorbers when liquid water is a challenge for a gearbox, but humidity does not cause problems.

AS-D

AS-D series adsorbers are acid separators. They consist of a PVC housing with activated carbon filling and are used to separate aggressive substances before they evaporate into the environment. Even when adsorbing formic acid and hydrochloric acid, the adsorbers remain stable over a long period of time.
As a disposable design, the AS-D adsorbers are easy to install and can be replaced efficiently and quickly.
They are mainly used in plants of the chemical industry, especially on IBC containers and drums. However, other plants can also be equipped with this adsorber.
