outer hub oil seal. Over time, the seal can wear out or become damaged due to exposure to extreme temperatures, moisture, and debris. If the seal is compromised, it should be replaced as soon as possible to avoid further damage to the wheel assembly.


Adsorption is another widely used method that relies on the attraction of gas molecules to solid surfaces. Activated carbon is commonly used in adsorption systems due to its high surface area and porosity, allowing it to effectively trap volatile organic compounds (VOCs) and other harmful gases. This method is particularly beneficial in industries dealing with solvents or petrochemicals, where VOC emissions can pose serious health risks and contribute to air pollution.

One of the most widely recognized pressure relief devices is the specialized mattress or mattress overlay. These products are designed to redistribute body weight and reduce pressure points, significantly lowering the risk of developing bedsores. Advanced options include alternating pressure mattresses, which use air cells that inflate and deflate cyclically to enhance circulation and relieve pressure. These innovative solutions are essential in hospitals and long-term care facilities where patients spend substantial amounts of time in bed.
