保护齿轮，防止腐蚀、油质下降、润滑不良和污染物泄漏。
您是否注意到变速箱油箱内有冷凝液滴，甚至更严重： 液压油中的铁锈、游离水和污垢、润滑不良、磨损迹象以及设备运行时的油味？原因是：每次吸入空气以平衡压力时，湿气和污垢颗粒都会不受阻碍地进入系统，此外，在呼气时还会逸散出油气溶胶。
面对现实吧，如果你不采取任何措施，你将面临昂贵的维护工作，并对员工和环境造成损害。
幸运的是，有一种解决方案：安装 GIEBEL Adsorber®。它可以干燥和清洁供气，防止污染物逃逸，为您节省维护工作和资金。
为什么水和污垢是您最关心的问题？
当金属与氧气和水发生反应时，这就是所谓的腐蚀。它会形成坚硬的高磨损性颗粒。在被水污染的齿轮油中，这些金属杂质会引发氧化连锁反应。自由基形成，攻击碳氢化合物分子并分解齿轮油。但这还不是全部：当机油添加剂与水发生反应时，会形成酸性物质，进一步加速分解。随着时间的推移，润滑性、粘度和剪切强度等机油特性都会发生变化。
由于流量特性较高，摩擦点不再需要提供必要的液压油量。另一方面，粘度极高的油会对系统的驱动装置造成压力并降低效率。油的老化残留物会堵塞阀门，油泥的形成会增加对过滤器的要求，而酸化则会增加所有金属部件的腐蚀风险，并损害密封件。
因此，防止湿气和灰尘进入以及防止腐蚀的形成，是齿轮箱长期、经济、低维护运行的首要任务！这正是我们的 GIEBEL Adsorbers® 所能做到的！

FAQ regarding gears.
Malfunctions & troubleshooting
Internal corrosion happens when condensation forms inside the gearbox, especially during temperature fluctuations or when machinery stands still. Rust leads to pitting, premature wear, and even complete component failure.
What you can do: Install a GIEBEL Adsorber® to prevent moist air from entering the gearbox, stopping condensation and internal corrosion.
Oil emulsification occurs when water enters the gearbox and mixes with the lubricant. This destroys the lubricating properties, increases wear on gears and bearings, and can lead to overheating. Moisture typically enters through ventilation points when the gearbox breathes during operation.
What you can do: Use a GIEBEL Adsorber® to filter out moisture from the intake air, preventing emulsification and protecting the oil’s performance.
Overpressure during operation causes seals to stress and eventually fail, leading to oil leaks. Pressure builds up from thermal expansion, especially if ventilation is blocked or ineffective.
What you can do: Equip your gearbox with a GIEBEL Adsorber® to allow balanced pressure equalization while filtering moisture and particles from incoming air.
Fine particles can enter through standard vents when the gearbox breathes, especially in dusty environments. These particles cause abrasion, increased friction, and lead to accelerated wear.
What you can do: A GIEBEL Adsorber® filters not just moisture but also fine particles, keeping your oil clean and protecting your gearbox from abrasive contamination.
Gear oil & filtration
Oil change intervals vary depending on operation time, load, and contamination levels. By preventing moisture and dirt ingress with a GIEBEL Adsorber®, oil stays cleaner for longer, meaning longer intervals between changes.
What you can do: Use a GIEBEL Adsorber® to reduce contamination levels, minimize oil degradation, and extend the oil’s usable life.
Typical signs include a milky appearance (due to emulsified water), darkened color, burnt smell, or visible particles. Monitoring these signs helps prevent severe damage, but prevention is key.
What you can do: Install a GIEBEL Adsorber® to prevent contamination altogether, keeping your oil clear and clean from the start.
Contaminated oil loses lubrication performance, increases friction, accelerates wear on gears and bearings, and can cause system overheating and premature failure.
What you can do: Prevent contamination with a GIEBEL Adsorber® and avoid the risks of costly repairs, downtime, and premature component failure.
Efficiency & optimization
Clean, dry oil reduces internal friction, ensures smooth gear operation, and minimizes energy losses due to drag or overheating. Preventing contamination directly improves overall efficiency.
What you can do: Use a GIEBEL Adsorber® to maintain clean, high-performance oil and keep your gearbox running at optimal efficiency.
By keeping out moisture and contaminants, GIEBEL Adsorbers® maintain oil quality, slow down oxidation processes, and extend oil life significantly.
What you can do: Equip your gearbox with a GIEBEL Adsorber® to reduce oil degradation, cut down on oil changes, and prolong equipment life.
Service & spare parts
Which ventilation dryer or oil mist separator is best suited to your system depends on various factors. These include, in particular, the size of your hydraulic tank and the operating location (e.g. indoor, outdoor, offshore, in explosion protection zones), the frequency of downtimes, your desired maintenance intervals and whether you prefer a disposable or reusable adsorber.
As a rule of thumb: The larger a gearbox, the larger a ventilation dryer or oil mist separator should be selected. The same applies to maintenance intervals. The further apart maintenance dates are, the larger the adsorber should be. Machines with long downtimes should use ventilation dryers with valves. These protect the desiccant of the adsorber from unnecessary loading. If your systems are operated in harsh environments or explosion protection zones, metal adsorbers are the right choice.
Use the configurator in our online store to find the right aeration dryer or oil mist separator for your system.
GIEBEL Adsorbers® are mounted on the gearbox breather port or via custom adapters. They are quick to install, even in retrofit applications, and work maintenance-free until the desiccant saturates.
What you can do: Install the adsorber on the breather connection point using the appropriate adapter and follow GIEBEL’s simple installation guidelines.
Our adsorbers feature a color-changing desiccant that visually indicates saturation. When the color fully changes, it’s time to refill or replace the drying agent.
What you can do: Check the desiccant color regularly and refill or replace the adsorber as soon as saturation is reached to maintain protection.
