Hydraulic power packs
When using hydraulic units, humid air is sucked in by pressure equalization with the environment, which condensate when the temperature drops below the dew point. The use in high humidity and temperature fluctuations can lead to condensation damage. Rapid aging of the hydraulic oil, the degradation of additives and the promotion of corrosion are only a few possible damages. To prevent damage caused by condensation, the use of a ventilation dryer is a very good measure. The incoming supply air is dried and thus a strong reduction in the water content and the dew point is achieved.
While a well designed ventilation dryer protects the hydraulic unit very efficiently, handling is very easy. The color change of the silica gel from orange to green indicates the status of the adsorber. GIEBEL FilTec has developed the VARIO and VENT series for protection of hydraulic power packs.

Hydraulics without an Adsorber
Particles and water are the main reason for malfunctions and damage in hydraulic systems, gears and bearings.
Problem
Condensation
Hydraulics without an Adsorber
1. Ambient air contains water
2. Level drops, moist air is sucked
3. Level rises, moist air flows out, part remains in the tank
Conclusion: Condensed water arises, oil absorbs the water, free water deposited
Solution
Hydraulics with GIEBEL Adsorbers®
1. Ambient air contains water
2. Level drops, moist air is dried
3. Level rises, dry air flows out, regenerates the adsorber
Conclusion: No condensation, no water in the oil, no free water

Adsorber
VENT PA-D
The GIEBEL adsorbers of the VENT PA-D series are cost-effective solutions with and without valves. From small versions with 0,15kg desiccant up to 3,0kg different hydraulic tanks can be ventilated.
VENT PA-R
The refillable desiccant filters VENT PA-R can also be equipped with or without plastic valves. By the possibility to exchange the desiccant and wear parts, these adsorbers have low operating costs.
VARIO PA-D
The GIEBEL series VARIO PA-D has a sturdy aluminum valve part and a disposable exchange cartridge. The handling is very simple, it will only open the latches and the entire cartridge can be changed.
VARIO PA-R
The GIEBEL adsorbers of the VARIO PA-R series are high-quality ventilation dryers with an aluminum valve part and a refillable cartridge. The desiccant and all wearing parts can be exchanged very easily.
VARIO MA
The VARIO MA adsorbers consist of an aluminum housing with valve part and are used for aeration of aggressive substances or for use in harsh environments. These adsorbers are filled with up to 10 kg of desiccant and can also be used for aeration of SKYDROL, brake fluids DOT4.
VARIO ME
The premium adsorbers VARIO ME are made entirely of A4 stainless steel. The use according to the ATEX product guideline 2014/34 / EU in the zone II 2 G / D IIC T4 is possible as well as after the corrosiveness category C5-M.
VARIO VG PA-D
The GIEBEL disposable adsorbers of the VARIO VG PA-D series are oil mist separators and are used for the adsorption of oil mist . Through the combination of impeller, oil dewater a high amount of activated carbon, the outflowing air is cleaned from hydraulic tanks.
VARIO VG PA-R
The GIEBEL reusable adsorbers of the VARIO VG PA-R series are oil mist separators and are used for the adsorption of oil mist. The function is the same as for the identical series VARIO VG PA-D, but the wearing parts can be changed individually.
Accessories
FLANGE ADAPTER
Suitable flange adapters are available for mounting a GIEBEL adsorber on a hydraulic tank. In the versions 3x M5 with bolt circle 41.3 mm or 6x M5 with bolt circle 73 mm according to DIN 42557 and as DN25 flange version, GIEBEL adsorbers can be easily mounted on all existing hydraulic systems.
FILLING ADAPTER
The use of a filling adapter makes it easy to refill oil into a hydraulic unit. The 40 mm-sized filler neck makes it very easy to fill in the oil without having to remove the adsorber.
PROTECTION ADAPTER
By using a protective adapter to monitor a GIEBEL adsorber, an optical or electronic signal is transmitted if the negative pressure is too high. This makes it possible to see whether a filter needs to be replaced.
OIL BYPASS ADAPTER
The bypass adapter allows the use of a bypass filter system without conversion measures on an existing hydraulic tank. At the same time, the use of a GIEBEL adsorber ensures ventilation and prevents further contamination of the hydraulic oil.
OIL MIST SEPERATOR
By using an oil mist separator, a GIEBEL adsorber is protected from contamination by larger oil particles. Used on systems with a high oil mist outlet, the proportion of evaporating oil particles is reduced with the oil separator and the air is cooled down.
WALL MOUNT
The wall bracket is suitable for the flexible installation of GIEBEL adsorbers with limited space available on the system. As a screw-on version for concrete walls, with clamping claws for steel girders or as a suspension version for grids or fences, no conversion measures are necessary on the system to use an adsorber.
MOUNTING TUBE
The mounting pipes facilitate the use of a GIEBEL adsorber if the adsorber can not be mounted due to its diameter.
ANGLE ADAPTER
The use of an elbow adapter makes it possible to mount a GIEBEL adsorber on a horizontal barrel and, when space is limited, on hydraulic power packs and gears. This is achieved, for example, by a horizontal or offset installation. The GIEBEL Adsorber can thus be aligned in the desired direction and fixed with the counter nut.
