There are compressors that do not use oil to operate and these are called oil free or screw compressors. It is through the action of screws that the air is compressed without the benefit of an oil seal. The pressure capacity of screw type air compressors are smaller compared to air compressor that uses oil. Since they have a small capacity and size, they are also less expensive.
The three types of screw compressors are the rotary screws, reciprocating air, and rotary centrifugal. The size and type of your operation determines the type of screw compressor to use. The rotary screw air compression is one of the most popular oil free compressors. It uses screws or rotors which maintain perfect alignment using timing gears. The risk of oil spills and contamination are reduced with the use of oil free compressors.
Oil free or screw compressors are ideal for small handyman jobs around the house. You can use two or three tools running at one with this type of air compressor. There are other uses of oil free compressors including medical research, and the food industry where it is unacceptable to have oil spills and run-offs. To a certain degree, screw type air compressors are also used in construction, auto manufacturing, and repair industries.
Oil free generators have a shorter life than those that use oil. These screw type air compressors are not as durable as oil compressors and will be likely to get knocked around because there is no metal surrounding them to protect them. Regular maintenance and proper care will help your screw air compressor to live a longer life.
The size of your air compressor will determine the amount of power that you need. There should be a careful reading of the instructions that come with your oil free air compressor. Or, inquire from the store staff where you bought your tool about its power requirements. You also need to consider the other tools you will be using. There should be enough amp power to run all of your equipment safely and effectively.
If you do online research, you will be able to get an idea of what you can purchase in the market. You can also check out their prices. Make sure that before buying the air compressor that you need, you already have a budget for it. Look for quality over price if you want your investment to last long. Maintaining and caring for your oil free compressor is important so you must know how to do it properly. It is important to carefully read the manufacturer’s instruction so that you can use your air compressor safely.
