An oil-flooded rotary screw air compressor needs regular preventative maintenance to stay in working order. It will also occasionally need repair to replace worn or broken parts.
Consumables requiring regular replacement may include intake filters, inline filtration (e.g., particulate or coalescing filters), oil filters, air/oil separator filters, cabinet filters.
Rotary screw oil (or piston oil, for reciprocating air compressors) must be changed regularly. Depending on the model and application, this may require synthetic compressor oil, blended oil or even food grade oil.
Hoses and belts wear out over time. They should be checked frequently and replaced when needed. Many compressed air applications require high pressure hoses; be sure to get the right kind of hose for your application.
Other compressor parts that may need to be changed occasionally include pressure switches, gauges, thermal valves, oil/water separators, pneumatic controls and automatic and zero-loss drains.
If the electric motor goes out, it may be fixable with the right parts, or it may require a new motor or a rebuild.
The air-end for a rotary screw air compressor should last for a very long time if the compressor is well maintained. The air end will typically last between 60,000 and 80,000 hours of operation before a rebuild is necessary. But when it gets to the end of its life, you will need a rebuild kit.
