An oil-free air compressor does not use oil to operate. Instead, the air is compressed by the action of screws. These types of compressors cannot handle the pressure capability of its oil counterparts. These compressors are also less expensive, due to their smaller capacity and size.
In general, there are three types of compressors. These are rotary screw compressors, reciprocating air compressors, and rotary centrifugal compressors. The uses of these compressors depend upon the size and operations. The rotary screw air compressor is one of the most popular oil-free compressor choices. It uses screws that maintain the perfect alignment in the timing gears. Oil-free compressors greatly reduce the risk of oil spills and contamination.
Uses of Oil-free air compressors
They can be used very effectively around the house for small jobs. These can be used as nail guns. They are also used in fields such as medical research, and the food industry where oil spills and run-offs would be considered unacceptable. Construction, auto manufacturing, and repair industries also use these types of compressors. These can be used in paintbrush also.
The lifespan of an Oil-Free Air Compressor
The lifespan of an oil-free compressor is not as long as compressors that use oil. They are not as durable and do not have the metal layer around them to protect them when they get knocked around. They break down more often. The life of these compressors can be extended with proper care and regular maintenance.
Power Needed for an Oil Free Air Compressor
The amount of power needed will ultimately depend on the size of the air compressor that you have chosen. You should always read the instructions carefully or get knowledge from the staff of the store from where you bought it. Be sure to take into consideration the other tools you will be using. You will need to have enough amp power to run all of your equipment safely and effectively.
An oil-free air compressor, although lighter and less durable, can still provide an output of 150 pounds per square inch gauge (psig), with a volume of over 2000 cubic ft. per minute. There are many different styles and brands of compressors, so shop carefully if you are looking to buy one.
Due to rising air pollution, the oil compressors are less used. You can visit this link to know the market growth of the oil-free compressors.
