Moisture in air line lubricators is detrimental because it can lead to rust and corrosion within the lubricator and the connected pneumatic equipment. When moisture is present, it combines with oil, which can lead to the formation of sludge and emulsions, reducing the lubricating properties of the oil. This can also lead to clogging in components, which impacts the overall performance and reliability of the system.
Additionally, the presence of water can corrode metal parts, creating debris that may further damage the equipment. This degradation can result in equipment failure, downtime for repairs, and increased maintenance costs. Hence, it's crucial to maintain a dry air supply to ensure the lubricators function properly and the longevity of the pneumatic systems.
