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. Comparing the oil free and its oil counterpart, oil free compressors cannot handle the same pressure capacity of compressors that use 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. You should purchase the type of screw compressor that fits the size and type of your operation. One of the most popular oil free compressors is the rotary screw air compressor. It uses screws or rotors which maintain perfect alignment using timing gears. Oil free compressors will eliminate the risk of oil spills and contamination.
Oil free or screw compressors are ideal for small handyman jobs around the house. They can generally keep two or three tools going at once. In medical research and the food industry, it is unacceptable to have oil spills and run-offs, so it is ideal to use screw air compressors in these fields. Other uses of screw air compressors are in construction, auto manufacturing, and repair industries to a certain degree.
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. However, with proper care and regular maintenance, the life of your oil free generator can be extended.
The size of your air compressor will determine the amount of power that you need. You should read the instructions carefully. You can also ask the staff from the store where you bought your compressor about the power requirements of your tool. If you are using other tools, make sure to consider their power requirements also. There should be enough amp power to run all of your equipment safely and effectively.
To get an idea of what is available in the market, you can do some online research. Visit online stores that sell screw air compressors and compare their prices to get the best deal. Set a budget ahead of time and buy only what you need. Your investment will last long if you check on quality first before considering the price. Maintaining and caring for your oil free compressor is important so you must know how to do it properly. It is always wise to read the manufacturer’s instructions carefully to ensure the safe and proper use of the equipment.
