What is the difference between a stationary compressor and a portable compressor?
A portable air compressor would be one small enough to carry or has wheels on it

The main difference between an oil free compressor and an oil flooded compressor is the method of injection to compress the air for mechanical equipment, most common being construction equipment. In the oil free compressor, air is injected with screws while an oil flooded compressor uses oil injected into the holes to create a seal.
