What could be a consequence of over-lubricating a pneumatic system?

Over-lubricating a pneumatic system can lead to a contaminated air supply. When there is too much lubricant present, it can mix with the air and create a mist or foam, which can be introduced into the air supply. This contamination can interfere with the operation of pneumatic components and lead to issues like increased wear, reduced efficiency, and even failures in air-operated devices. A clean air supply is essential for the proper operation of pneumatic systems, and excess lubricant can significantly compromise this, leading to potential damage or malfunction of the equipment.
