Protect gears against corrosion, loss of oil quality, poor lubrication & the escape of pollutants.
Have you noticed condensation droplets inside your transmission tank or even worse: Rust, free water and dirt in hydraulic oil, poor lubrication, signs of abrasion and an oily smell when the unit is running? The cause: moisture and dirt particles entering your system unhindered every time it draws in air to equalize pressure, plus oil aerosols escaping when it breaths out.
Let‘s face it, if you don‘t do anything about it, you‘re heading for expensive maintenance work and damage to employees and environment.
Luckily, there‘s a solution: the installation of an GIEBEL Adsorber®. It dries and cleans the supply air and prevents pollutants from escaping - saving you maintenance work and money.
Why water & dirt should be you biggest concern?
When metals react with oxygen and water, this is known as corrosion. It leads to the formation of hard, highly abrasive particles. In gear oil contaminated with water, these metallic impurities trigger an oxidative chain reaction. Free radicals are formed, which attack the hydrocarbon molecules and break down the oil. But that‘s not all: when oil additives react with water, acids are formed that further accelerate the decomposition. Over time, oil properties such as lubricity, viscosity and shear strength change.
With higher flow characteristics, friction points are no longer supplied with the necessary volume of hydraulic oil. Extremely viscous oils, on the other hand, put a strain on the system‘s drive units and reduce efficiency. Oil ageing residues clog valves, sludge formation increases filter requirements and acidification hightens the risk of corrosion of all metallic components, plus impairs the seals.
Preventing the entry of moisture and dirt as well as the formation of corrosion is therefore the top priority in order to operate gears for a long time, cost-effectively and with low maintenance! And that is exactly what our GIEBEL Adsorbers® do!

FAQ - your questions, answered.
A GIEBEL Adsorber® is a desiccant filter that removes moisture and contaminants from the supply air to hydraulics, gears, storage tanks, barrels, IBCs and transformers. It prevents the formation of condensation inside these systems and the associated damage, such as corrosion and oil degradation.
The core of a GIEBEL Adsorber® is the high-performance desiccant GIEBEL Xdry®,
consisting of silicagel orange-green and molecular sieve 13X. It offers a significantly higher drying capacity than traditional silica gel and keeps your system reliably dry even at high temperatures and low
humidity levels.
Valves protect the breather dryer from
unnecessary loading on systems with long downtimes, and our versatile
connections and accessories make installation a breeze—even in tight
spaces.
A GIEBEL
Adsorber® directs the airflow into your system through a desiccant and a 3-micrometer filter, ensuring that moisture and contaminants cannot cause damage inside. It provides reliable protection against corrosion, the degradation of operating oils, and the breakdown of additives.
When air is forced out of the system, the adsorber also filters oil particles and aerosols from the exhaust air.
A GIEBEL Adsorber® protects your system from day one. By preventing damage, it ensures that a plant remains low-maintenance, durable, and profitable.
Of course, an adsorber can also be retrofitted at any time. Clear indications that you need a breather filter include a measurable decline in the quality of the operating oil, condensation droplets in the tank or on the tank cap, or early signs of corrosion.
