Everything you need to know about compressed air:

Splash lubrication is the simplest lubrication method. A pin, which is attached to the crankshaft, dips into the oil each time the crankshaft rotates and sprays the bottom of the pistons and the cylinder walls. The oil spray mist that is formed also ensures lubrication of the rotating parts within the compressor. The prerequisite for effective lubrication is an almost horizontal position of the compressor.
Splash lubrication is used mainly in small reciprocating compressors, which are only operated intermittently and, in addition, should also be portable. It works regardless of the direction of rotation.
The best system of lubricating the moving parts in a compressor is pressure lubrication by means of an oil pump (low pressure approx. 3-4 bar). This type of lubrication is independent of the oil level in the crankcase. In contrast to splash lubrication, this method allows the compressor to be positioned at angles of up to 20°, depending on the model.
Mineral or synthetic oils are used for lubrication. Synthetic oils are recommended for heavy-duty compressors in around-the-clock operation.
The oil should be changed at the following intervals:
- 2000 h for synthetic oils
- 1000 h for mineral oils
