Purchasing Resources for Oil-Free Compressors
Download Oil-Free Compressors White Papers
Many industries use oil-free compressors, including the medical, industrial and construction industries. They are power tools that can be used in small industrial shops or large manufacturing firms. You can use them to fill tires, clean workspaces and to blow dust from areas that are hard to reach. They have a start motor and can run off of regular household electrical circuits. Although they are lightweight and easy to carry around, they have the same amount of power as oil-filled compressors and typically last for many years.
Reciprocating compressors are the most popular type of oil-free compressors available. Air that enters an oil-free reciprocating compressor is confined to a small, enclosed space. The air is then elevated to a higher pressure and released at a high speed. Centrifugal compressors use a rotating impeller to capture the air from one side and release it from the other. This type of compressor operates at an even higher speed; however, it provides the same amount of pressure that reciprocating compressors provide. Rotary screw compressors are ideal for industrial environments. They have multiple rotating screws and provide the highest amount of pressure. You do not have to lubricate rotary screw compressors, but some users find that lubricating them enhances their power and performance.
