There are compressors that do not use oil to operate and these are called oil free or screw compressors. In this type of air compressor, screws are used to compress air without any oil seal. The pressure capacity of screw type air compressors are smaller compared to air compressor that uses oil. Oil free compressors are also cheaper than air compressors using oil since their capacity and size are small.
Screw compressors come in three different types including the rotary screws, reciprocating air, and rotary centrifugal. The screw air compressor that you need will depend on how big of what kinds of operation you are going to do. One of the most popular oil free compressors is the rotary screw air compressor. This type of air compressors is able to maintain perfect alignment using timing gears with the use of screws or rotors. 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. With this type of air compressors, you can use 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.
Screw air compressors live a shorter life than their oil counterparts. 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.
When it comes to determining the amount of power that you need for your air compressor, this will depend on its size. You should read the instructions carefully. Or, inquire from the store staff where you bought your tool about its power requirements. If you are using other tools, make sure to consider their power requirements also. If you want to run all your equipment safely and effectively, there should be enough power to run all of them.
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. Set a budget ahead of time and buy only what you need. Quality should be preferred over cost when choosing a screw air compressor. Know how to properly care for and maintain your oil free compressor. It is always wise to read the manufacturer’s instructions carefully to ensure the safe and proper use of the equipment.
